A note from James, who actually slept on it
Lead tester · 86kg / 13st 8lb · hot sleeper · back/side combo · former Silentnight QC — not the 104kg tester
Springs are not a slogan. A 16cm pocket spring is a support job. A 2cm pocket spring is a first-hit job. OTTY Pure Pro — still listed as Pure 3000 in the URL — stacks both. Up to 2,000 of the tall encapsulated coils sit where Original and Pure put them. Up to 1,000 short coils sit in the quilted comfort layer, under the embroidered cover that already holds 2cm of bamboo and charcoal foam. That is why OTTY can print “up to 3,000” without this being a 32cm double-unit. 27cm. Printed 7/10. If you came here expecting Pure+’s 4,000-spring stack, you wanted Pure+. More springs is not automatically more support at 104kg, and it is not automatically more hug at 62kg. Those extra thousand are 2cm first-hit coils, not a thicker core and not a softer flagship.
I pressed the cover with a thumb in a Nottingham Lace Market conversion — brick, tall windows, no AC, a king that had to come up a tight stair. I am 86kg / 13st 8lb — the lead reviewer, not the 104kg tester. The 2cm heads answered first. Then the 16cm unit. Emma Thompson, 71kg / 11st 2lb on her side, hot sleeper, wanted more give than 7/10 and did not get it. David Patel, 104kg / 16st 5lb on his back, sits on the edge, already liked Original’s bounce and could not feel a second spring layer worth the climb. Sarah Mitchell, 62kg / 9st 11lb on her side, could feel the extra coil layer with a thumb and forget it by 2am. They are 42kg apart on the same 3,000-spring stack — that gap is the decision, not a rounding error. Rachel Adams, 68kg / 10st 10lb, physio lens, needed a 200 × 200 Emperor. The picker does not sell one. All five were telling the truth about the same mattress. Three of them would not buy it. That stays.
We score it 4.2/5 — not 4.6, and not 5 — because the comfort-spring layer is a real construction difference, the from-price is only about £15 above Pure, and then king and super king jump hard. It is not automatically a better Pure. Below is the buyer’s guide: the 2cm layer in plain English, four nights in named Nottingham rooms, kilogram figures on why Emma, David and Rachel would not buy it, and the three reasons not to buy it. None of this is sponsored copy.
Quick verdict for UK buyers
Best OTTY if you already wanted Pure’s charcoal and a thin comfort-spring layer without Pure+ height. We score it 4.2/5 because the 2cm coils are a genuine extra job, Dual Airflow side support is on the spec, a small double is actually sold — and then the till argues. From £539.99 looks like a rounding error next to Pure’s from-price. A king was £799.99 against Pure’s £724.99 the day we checked. Super king £899.99 against £824.99. That is the review as much as the springs. I am 86kg / 13st 8lb on this king — household-average, not David’s 104kg / 16st 5lb night.
OTTY still prints 7/10, the same number as Original. Pure is 6.5. Pure+ is 5.5. “Pro” here does not mean plusher. It means an extra thousand short coils on a firmer Pure stack. Emma Thompson at 71kg / 11st 2lb wanted the 5.5. This was not her mattress. Sarah Mitchell at 62kg / 9st 11lb did not get extra hug from the extra springs. David Patel at 104kg / 16st 5lb did not get extra support from them. Three people on the panel would not buy it — Emma, David, Rachel — and the kilogram figures are why, not a slogan. Use the 100-night trial like an adult, not a ten-minute sit in a shopping-centre concession.
Bottom line: charcoal foam, 27cm, you can feel the 2cm layer, you do not need EU sizes. Continental or Emperor frame — look at Pure. Side sleeper who actually wanted 5.5/10 — Pure+. Not sure this is the OTTY — start on which OTTY should I buy?.
Who the Pure Pro is for
Buy this if
- You wanted Pure’s bamboo and charcoal plus a second spring job — 1,000 × 2cm comfort springs on top of the 16cm unit — without Pure+ height.
- You like Original’s 7/10 medium-firm and still wanted the charcoal stack. This is not a softer Pure. James Wright at 86kg / 13st 8lb is that combination night — the lead reviewer, not the 104kg tester.
- You need a UK small double. OTTY actually sells 120 × 190cm on this model. Pure+ is the one that skips 4ft.
- You will pay the king or super king jump because you can feel the comfort-spring layer, not because the from-price looked like £15.
Skip this if
- You need an EU Double, EU King, or Emperor. Pure Pro’s picker is narrower than Pure. Rachel Adams at 68kg / 10st 10lb — physio lens, Wollaton Emperor frame — died here. Buy Pure.
- You already sleep well on Original at around 104kg and did not need a second spring layer. David Patel at 104kg / 16st 5lb, back sleeper, sits on the edge. That money is a sale Original, not a Pro tax. More springs is not automatically more support at his weight.
- You are a side sleeper who actually wanted Pure+’s 5.5/10. Emma Thompson at 71kg / 11st 2lb, hot sleeper, her shoulder. This prints 7/10. The 2cm coils do not make it a marshmallow. Sarah Mitchell at 62kg / 9st 11lb did not get extra hug from the extra springs either.
- You are shopping the from-price and assuming a king is only £15 more than Pure. It is not. Open the size picker.
Buy, trial, or skip
Match the kilogram figure nearest yours. James at 86kg / 13st 8lb would buy Pure Pro for someone who already wanted charcoal plus the 2cm first-hit layer without Pure+ height — he is the lead reviewer, not the 104kg tester. Three of five testers would not buy it. Sarah at 62kg / 9st 11lb and David at 104kg / 16st 5lb slept on the same 27cm, 7/10, 3,000-spring stack and disagreed: extra springs were not extra hug at 62kg, and not extra support at 104kg. That 42kg gap is the decision.
| If you are… | Verdict | Why |
|---|---|---|
| A 62kg side sleeper (Sarah’s build) | Trial first | Motion was fine on a Mapperley king. At 62kg / 9st 11lb the extra 1,000 × 2cm coils are a thumb-test, not Pure+ hug — she could feel them and forget them by 2am. Seventy-five pounds over Pure’s king is a skip if Pure already worked. More springs is not automatically more hug at her weight. |
| An 86kg combination sleeper (James’s build) | Buy on sale | He can feel the 2cm layer with a thumb. He would buy it for charcoal plus that first-hit coil without Pure+ height — not as an automatic climb from Original, and not because the from-price is £15. He is 86kg / 13st 8lb, the lead reviewer, not the 104kg tester. Wait for DREAMY26 or whatever banner is live. |
| A 104kg / 16st 5lb back sleeper (David’s build) | Skip | Hips stayed up — that is the 16cm unit, the same tall core as Original. The extra thousand 2cm coils did not rewrite his night at 104kg / 16st 5lb. Sitting on the edge was fine for a minute. More springs is not automatically more support at his weight. Sale Original is his OTTY. |
| A couple about 42kg apart (Sarah–David gap) | Trial first | Same 3,000-spring Pure Pro, two different jobs. At 62kg she does not travel far enough for the 2cm layer to become a hug. At 104kg he loads the 16cm unit and the extra thousand short coils do not add a support job. One mattress cannot run two spring jobs. The 100 nights are the product. |
| A 71kg side sleeper who wanted 5.5/10 (Emma’s build) | Skip | Emma Thompson at 71kg / 11st 2lb, hot sleeper, came in for Pure+. She got 7/10. The 2cm comfort springs take the first inch; they do not turn this into the soft OTTY. Pro is not plusher. Buy Pure+. |
| An Emperor, EU Double or EU King frame (Rachel’s situation) | Skip | Rachel Adams at 68kg / 10st 10lb, physio lens, already owned a 200 × 200 Emperor. Pure Pro’s picker does not sell one. Pure still does. That is a sizing problem, not a comfort one. Do not let a from-price of £539.99 talk you onto a mattress that does not exist in your size. |
| Shopping the from-price and assuming a king is £15 more than Pure | Skip | Pure from £524.99, Pure Pro from £539.99 on 5 September 2026. About £15 — that is a single. King is £824.99 versus Pure’s £749.99. Super king jumps the same way. Open the size picker. |
The 2cm comfort springs — not a second mattress
The clever bit is the short coil layer. OTTY’s support unit is still the familiar 16cm encapsulated pocket springs — up to 2,000 of them, the same height as Original and Pure. On top of that unit, in the quilted comfort layer, sit up to 1,000 springs that are only 2cm tall. Your shoulder hits those first. The tall coils hold the rest of you. Add them and you get the “up to 3,000” badge. 27cm. Printed 7/10. Do not picture two full mattresses stacked. Picture a sprung topper that was sewn into the bed, sitting under 2cm of bamboo and charcoal foam in the embroidered cover.
I can tell the difference in ten seconds. Press Pure and the foam answers, then the 16cm heads. Press Pure Pro and the 2cm heads click first — a tighter, shallower answer — then the tall unit. Emma Thompson at 71kg / 11st 2lb wanted a slower, deeper drop. She did not get one. David Patel at 104kg / 16st 5lb already had Original’s bounce. The extra thousand did not rewrite his back — more springs is not automatically more support at 104kg. Sarah Mitchell at 62kg / 9st 11lb is 42kg lighter on the same stack: the extra springs are not automatically more hug at 62kg either. Rachel Adams at 68kg / 10st 10lb never got that far: her Emperor frame is not on this picker.
That is why 62kg and 104kg cannot share a verdict on a 3,000-spring badge. Sarah at 62kg / 9st 11lb does not travel far through the quilt: 7/10 still reads as Original’s number, and the 2cm layer is a first inch she can feel with a thumb. David at 104kg / 16st 5lb loads the 16cm unit — hips stay up, same as Original — and the extra thousand short coils do not become a thicker support core. James at 86kg / 13st 8lb sits between them and can feel the first-hit job without needing a new mattress class. This is how far two bodies went through one OTTY hybrid.
Pure+ is the other dual-spring OTTY: up to 4,000 coils, 28cm, printed 5.5/10. That is a different mattress — taller, softer, extra-deep sheets, no small double. If you only wanted charcoal without a second spring job, Pure is the one to buy. If you wanted the short-coil first hit without dropping to 5.5, stay here and pay the size ticket with your eyes open.
Four nights that were not a lab
Named people, real rooms and UK duvets rather than a panel average. This one was slept on in Nottingham.
Emma Thompson — 71kg, West Bridgford terrace, wanted 5.5
Emma Thompson is 71kg / 11st 2lb, 170cm, side-dominant, hot sleeper, former Good Housekeeping interiors writer. Two-up-two-down in West Bridgford, sash windows, no AC, 13.5 tog still on because August had been sticky rather than dramatic. She came in wanting Pure+’s printed 5.5/10. She got Pure Pro’s 7/10. She would not buy it. The kilogram figure is why: at 71kg the 2cm comfort springs take the first inch and then the floor of 7/10 arrives.
“The short springs take the edge off the first inch. They do not turn it into the soft OTTY. My shoulder wanted more. I would buy Pure+ for me. I would not buy this because the name says Pro and I assumed plusher.”
Sarah Mitchell — 62kg, Mapperley, motion, then the king ticket
Sarah Mitchell is 62kg / 9st 11lb, 165cm, side sleeper. Founder, former Telegraph sleep editor. Shared a king with a restless partner in a Mapperley top floor that holds the day’s heat. Dual spring layers are supposed to isolate. She got a decent night. Then she opened Pure’s king price. At 62kg the extra 1,000 × 2cm coils were not automatically more hug — a thumb-test she forgot by 2am. She is 42kg lighter than David on the same stack.
“When he got up for water I moved less than I do on a cheap guest hybrid. Fine. Then I saw Pure’s king at £749.99 and this at £824.99. Seventy-five pounds for a 2cm coil layer I can feel with a thumb and forget by 2am. I would not pay that difference if Pure already felt like enough.”
David Patel — 104kg, Beeston semi, already had Original
David Patel is 104kg / 16st 5lb, 178cm, back sleeper, sits on the edge. Technical editor, former Which? tester. A week as a main bed in a 1930s Beeston semi. He already liked Original’s 7/10 bounce. The question was whether a second spring layer earned the extra money. He would not buy it. Hips stayed up — that is the 16cm unit, the same tall core as Original. The extra thousand 2cm coils did not rewrite his night. More springs is not automatically more support at 104kg. That is not James at 86kg having a slightly heavier week.
“My hips stayed up. That part is fine. I could not honestly say the extra thousand 2cm coils changed my night versus Original. Charcoal foam is a nicer story. It is not a different mattress at my weight. Put me on a sale Original. This one is a construction upgrade I did not need.”
Rachel Adams — 68kg, Wollaton, Emperor frame, dead picker
Rachel Adams is 68kg / 10st 10lb, 172cm, mixed positions, physio lens. She was shopping for a 200 × 200 Emperor in a Wollaton spare room that already had the frame. Pure still lists Emperor. Pure Pro does not. EU King 160 × 200 is also missing. The review ended at the size picker. She would not buy it because OTTY will not sell the footprint she already owns — a sizing problem at 68kg, not a comfort complaint.
“I never got a fair night on this model because OTTY will not sell me the footprint I already own. That is not a comfort complaint. That is a sizing problem. Buy Pure if the bed is continental or a 200cm square. Do not let a from-price of £539.99 talk you onto a mattress that does not exist in your size.”
Who slept on it (including the three who would not buy it)
Why 62kg and 104kg disagree
Sarah Mitchell sleeps at 62kg / 9st 11lb. David Patel sleeps at 104kg / 16st 5lb — 42kg more on the same surface. That is not a rounding error. A heavier torso compresses foam further before the springs (or the next foam layer) say stop. A mattress that cradles Sarah’s shoulder can become a crater under David’s hips. A mattress that holds David’s lumbar can feel perched to Sarah. James Wright, the lead reviewer, is 86kg / 13st 8lb — between them, which is why his score is often the household average and not the last word.
On Pure Pro that 42kg gap is why extra springs are not a slogan. Sarah at 62kg / 9st 11lb does not travel far through the quilt: the 1,000 × 2cm comfort springs are a first-inch thumb-test, not Pure+ hug, and 7/10 still reads as Original’s number. David at 104kg / 16st 5lb loads the 2,000 × 16cm unit — hips stay up, same as Original — and those extra thousand short coils do not become a thicker support core. More springs is not automatically more hug at 62kg, and it is not automatically more support at 104kg. James at 86kg / 13st 8lb sits between them and can feel the first-hit job — he is the lead reviewer, not the heavy tester. Emma Thompson at 71kg / 11st 2lb is the hot sleeper whose veto was 7/10, not a crater. Rachel at 68kg / 10st 10lb never got a fair night: no Emperor on this picker. Three of five would not buy it. That honesty stays.

James Wright4.2
86kg / 13st 8lb · 183cm · Back/side combination · Nottingham Lace Market king
“The 2cm layer is real. I can feel it with a thumb. I would buy it for someone who wanted charcoal plus that first-hit coil without Pure+ height. I would not pay the king jump over Pure on a night I already liked. I am 86kg / 13st 8lb, the lead reviewer, not the 104kg tester.”
Sarah Mitchell3.9
62kg / 9st 11lb · 165cm · Side sleeper · Mapperley king · would skip the till
“Motion was fine. The king ticket versus Pure is the review. Seventy-five pounds for a coil layer I forget by 2am is a skip if Pure already worked. At 62kg / 9st 11lb extra springs were not extra hug.”
Emma Thompson3.6
71kg / 11st 2lb · 170cm · Side-dominant combination · Would not buy — wanted Pure+
“Pro did not mean plusher. 7/10 is Original’s number. My shoulder wanted Pure+. This is the wrong climb if you came for soft. I am 71kg / 11st 2lb and I sleep hot — firmness was the veto, not heat.”
David Patel3.7
104kg / 16st 5lb · 178cm · Back sleeper; sits on the edge · Would not buy — sale Original
“Hips stayed up. I did not need a second spring layer. Sale Original is my OTTY. Charcoal is not a reason to climb. I am 104kg / 16st 5lb — more springs is not automatically more support at my weight.”
Rachel Adams3.2
68kg / 10st 10lb · 172cm · Mixed positions (physio lens) · Would not buy — no Emperor
“No Emperor. No EU King. The picker is narrower than Pure. I cannot review a mattress OTTY will not sell me in the size I already own. I am 68kg / 10st 10lb. That is a sizing problem, not a comfort complaint.”
The case against the Pure Pro
We give it 4.2/5. The missing points are not rounding errors.
- The picker is narrower than Pure. Small double is sold — good. EU Double 140 × 200, EU King 160 × 200, and Emperor 200 × 200 are not. Pure still lists all three. Rachel Adams at 68kg / 10st 10lb, physio lens, Wollaton Emperor frame ended the review at checkout. If the bed you already own is continental or a 200cm square, this model is the wrong OTTY. Buy Pure and stop reading Pro blogs.
- The from-price lies about king and super king. Pure from £524.99, Pure Pro from £539.99 on . About £15. Then open the size picker: Pure king £749.99 versus Pure Pro king £824.99; super king £849.99 versus £924.99; double £649.99 versus £749.99. Sarah Mitchell at 62kg / 9st 11lb: seventy-five pounds on the same footprint for a 2cm coil layer you can feel with a thumb and forget by 2am. Extra springs were not extra hug at her weight. The construction difference is real. The till is also real. It is not automatically a better Pure.
- 7/10 is Original’s number, not a softer Pure — and 3,000 springs is not a heavier-sleeper upgrade. OTTY prints medium-firm 7/10 — same as Original, firmer than Pure’s 6.5, a long way from Pure+’s 5.5. Emma Thompson at 71kg / 11st 2lb on her side wanted the flagship give and did not get it. David Patel at 104kg / 16st 5lb already liked Original’s bounce and did not need a second spring layer — more springs is not automatically more support at 104kg. Sarah Mitchell at 62kg / 9st 11lb did not get extra hug from the extra thousand 2cm coils either. “Pro” is an extra thousand short coils on a firmer charcoal stack. It is not a reason to skip Pure+ if you actually came for 5.5/10.
Pros and cons
Pros
- Real extra job: 1,000 × 2cm comfort springs over the 16cm unit
- Bamboo and charcoal comfort foams, Dual Airflow side support, 27cm printed
- UK small double is actually sold
- 100-night trial, 10-year warranty, CertiPUR / Europur, FIRA
- From-price only about £15 above Pure if you are actually buying a single
Cons
- No EU Double, EU King, or Emperor — narrower than Pure
- King and super king jump hard versus Pure; double jumps £100
- Prints 7/10 — not a softer Pure, not Pure+’s 5.5
- Original buyers at 104kg / 16st 5lb may not feel a second spring layer worth the climb — David’s skip
- 100 nights, not Emma’s 200 or Nectar’s 365
- 3,000 springs is not automatically more hug at 62kg or more support at 104kg
How we scored it
Category scores
Each bar is /100. Support (85) is the 16cm unit — hips stayed up for David Patel at 104kg / 16st 5lb, the same job Original already did. Comfort (83) is James’s 86kg first-hit night, pulled down because Sarah at 62kg did not get extra hug from the extra springs and Emma Thompson at 71kg wanted 5.5. Edge support (76) is Dual Airflow plus David sitting to put socks on. Cooling (73) is James and Emma in a still Nottingham week with a 13.5 tog and no air-con. Value (66) is the king till versus Pure. Comfort and support lead the published method.
Weighting follows our published method: comfort and support first, then cooling, motion, edges, durability and value. Support is Pure Pro’s high score — the 16cm unit plus Dual Airflow, which held David at 104kg / 16st 5lb the same way Original did. Value is marked down because the from-price flatters a single and king/super king do not. Cooling sits in the middle: hybrid airflow for James at 86kg / 13st 8lb and Emma Thompson at 71kg / 11st 2lb.
What is inside: seven technology steps
OTTY’s live Pure Pro page walks seven steps. Pure walks six — the missing one is the 1,000 comfort springs. That is the whole upgrade in a list. Foam is CertiPUR and Europur. Fire testing is FIRA / BS7177 as OTTY states it. Rotate; do not flip. Some retailer listings paste Pure+ wording onto this mattress; it is not 4,000 springs and it is not 5.5/10.
| # | Layer | What it does |
|---|---|---|
| 1 | Infused embroidered cover | Embroidered knit with 2cm of bamboo and charcoal infused memory foam quilted in. First thing your shoulder meets. Rotate the mattress; do not flip it. Follow OTTY’s wash label — we did not strip ours to run a laundry experiment. |
| 2 | Charcoal & bamboo memory foam | The comfort foam OTTY sells as moisture and odour control. Emma Thompson at 71kg / 11st 2lb still ran a 13.5 tog in West Bridgford. This is polymer with a story, not a chimney. It is still cooler than a 2014 closed-cell slab. |
| 3 | 1,000 × 2cm comfort springs | The clever bit. Encapsulated pocket springs in the quilted / comfort layer. They take the first hit. They are not a second 16cm unit. Press the cover: these heads answer first. At 62kg Sarah felt them with a thumb and forgot them by 2am. At 104kg they did not become extra support for David. More springs is not automatically more hug or more hold. |
| 4 | High-density support foam | OTTY calls this reflex foam — extra support on top of the tall spring unit. It is the pad between the short coils and the 16cm core, not a zoned foam mattress on its own. |
| 5 | Up to 2,000 × 16cm pocket springs | The support job. Same tall encapsulated unit as Original and Pure. This is why hips stayed up for David Patel at 104kg / 16st 5lb. “Up to” means count scales with size — a single does not hold 3,000 coils. Extra thousand 2cm coils sit above this unit; they are not a thicker core. |
| 6 | Dual Airflow side support | OTTY prints Airflow side support ×2 on this model — edge-to-edge surface plus the usual perforated airflow story. I sit to put socks on at 86kg / 13st 8lb and the corner is usable, not a hotel bench. David at 104kg / 16st 5lb sitting was heavier and still fine for a minute. Better than all-foam. Not a divan perch. |
| 7 | High-density base foam | Foundation slab. Single-sided. Keep slat gaps honest — OTTY will not love thin steel bars. The 10-year paperwork assumes a decent base. |
Depth is printed: 27cm on every size we opened, including the single 90 × 190 × 27. Pure prints 25cm. Pure+ prints 28cm. The extra 2cm versus Pure is the comfort-spring layer plus the extra foam in the quilt, not a mystery. If your bunk has a hard cap, measure the expanded mattress. Ignore any listing quoting 26cm or 30cm — that is not what OTTY publishes.
Firmness: 7/10 is Original’s number
OTTY prints medium-firm 7/10. That is the same published number as Original. Pure is 6.5. Pure+ is 5.5. The 2cm comfort springs add a first-hit give under the quilt. They do not rewrite the scale. For Emma Thompson at 71kg / 11st 2lb on her side, the floor arrived too soon. For James Wright at 86kg / 13st 8lb as a combination sleeper in the Lace Market king — the lead reviewer, not the 104kg tester — it read like Original with a sprung topper sewn in. For David Patel at 104kg / 16st 5lb on his back, hips stayed up — which is the 16cm unit doing its job, not a new firmness class and not extra support from the extra thousand 2cm coils. For Sarah Mitchell at 62kg / 9st 11lb the extra springs were not extra hug.
Ten minutes in a concession will feel firmer than night four in a warm Nottingham flat. Foam warms; short coils take a shoulder. That is why Emma’s morning complaint and James’s thumb test can both be true. Use a shop to reject bounce you hate. Use the 100 nights to live with 7/10.
Sleep positions and body weight
| Sleeper | Fit | Notes |
|---|---|---|
| Side | Fair | The 2cm layer helps the first inch. Emma Thompson at 71kg / 11st 2lb still wanted Pure+’s 5.5/10 — she would not buy it. Sarah Mitchell at 62kg / 9st 11lb: extra springs were not extra hug. Average-weight sides who like Original’s 7/10 will be closer. Use the trial. |
| Back | Good | David Patel at 104kg / 16st 5lb: hips stayed up. He still would not pay the climb over Original. The support is there — the same 16cm unit. The second spring layer is optional at his weight. More springs is not automatically more support at 104kg. |
| Stomach | Fair | 7/10 is a more honest front-sleeper number than Pure+’s 5.5. Lightweight fronts may last a trial. Emma Thompson at 71kg / 11st 2lb is side-dominant and still found 7/10 too firm for a shoulder, which tells you a dedicated stomach sleeper who wants a hard bed should open Extra Firm, not this. |
| Combination | Good | James’s night at 86kg / 13st 8lb: you can turn. The short coils take the first roll; the 16cm unit pushes back. Less dough than all-foam. Not a trampoline. He is the lead reviewer, not the 104kg tester. |
OTTY’s Pure Pro page does not print a per-side weight limit we could copy. Treat David’s 104kg / 16st 5lb week as “support is fine, upgrade is optional,” not a lab measurement. Above that, Extra Firm is the OTTY that actually wants 15st+ on its marketing. Do not hope 2cm coils “bed in” under a heavier frame. Sarah at 62kg / 9st 11lb is 42kg lighter on the same stack — extra springs were not extra hug at her weight either.
Body weight is not a vibe. It is how far you travel through the comfort layer before the core holds you. Sarah at 62kg / 9st 11lb often needs a softer top so her shoulder can drop. David at 104kg / 16st 5lb often needs that same top to stop sooner, or his hips make a hammock. James at 86kg / 13st 8lb sits between them — useful as a typical UK male, useless as a stand-in for a 104kg back sleeper. If you are shopping this OTTY Pure Pro Hybrid because a review said “medium-firm,” match the kilogram figure nearest yours, not the brand icon.
| Tester | Weight | Fit | What that weight actually did |
|---|---|---|---|
Sarah Mitchell | 62kg / 9st 11lb | Mixed | At 62kg / 9st 11lb on her side the 1,000 × 2cm comfort springs were a thumb-test, not Pure+ hug. Motion was fine. Seventy-five pounds over Pure’s king is the review. Extra springs are not extra hug at 62kg. Score 3.9. |
James Wright | 86kg / 13st 8lb | Good | 86kg / 13st 8lb is the household-average body. He can feel the 2cm first-hit layer and would buy it for charcoal without Pure+ height — not as an automatic climb from Original. He is the lead reviewer, not the 104kg tester. |
Emma Thompson | 71kg / 11st 2lb | Poor | 71kg / 11st 2lb, hot sleeper, side-dominant. She wanted Pure+’s 5.5/10. She got 7/10. The 2cm coils take the first inch; they do not make Pro plusher. Firmness was the veto, not heat. She would not buy it. |
Rachel Adams | 68kg / 10st 10lb | Skip | 68kg / 10st 10lb, physio lens, mixed. Alignment never got a fair night: no Emperor, no EU King on this picker. A sizing problem. Buy Pure if the frame is already 200 × 200. |
David Patel | 104kg / 16st 5lb | Mixed | 104kg / 16st 5lb on his back, sits on the edge. Hips stayed up — the 16cm unit, same as Original. The extra thousand 2cm coils did not rewrite his night. More springs is not automatically more support at 104kg. Sale Original. Score 3.7. |
Find yourself on the scale
Use these bands as a first filter, then use the trial. They are how this mattress behaved for our panel, not a medical chart. A 95kg side sleeper is not David, and a 70kg stomach sleeper is not Sarah.
| Your weight | Fit on this mattress | Read this first |
|---|---|---|
| Under 70kg | Mixed | Sarah at 62kg (side) did not get extra hug from the extra springs. Rachel at 68kg (mixed) never got a night in her Emperor size. Side sleepers in this band who wanted 5.5 should open Pure+, not this 7/10. |
| 70–90kg | Good | James’s 86kg combination night lives here — charcoal plus first-hit coils without Pure+ height, on a sale. Emma Thompson at 71kg is in this band; her caveat was 7/10 on her side, not a crater. It suits mixed back and side sleepers who already liked Original’s firmness. |
| 90–110kg | Mixed | David at 104kg / 16st 5lb found support fine and the upgrade optional. The 16cm unit held his hips. The extra 2cm layer did not earn the climb over Original. Use the 100 nights, or stay on a sale Original. |
| Heavier than our 104kg tester | Skip | OTTY does not print a useful per-side kilogram limit on the Pure Pro page we used. David at 104kg already did not need the second spring layer. Extra Firm is the OTTY that markets 15st+. Do not hope 2cm coils bed in under a heavier back sleeper. |
This brand does not print a useful per-side kilogram limit on the product page we used. Treat David’s 104kg week as a comfort signal, not a lab certificate, and use the home trial if you are in his weight class.
Sarah and David are 42kg apart. On Pure Pro she does not travel far enough for the 2cm layer to become a hug; he loads the 16cm unit and the extra thousand short coils do not add a support job. Extra springs are not extra hug at 62kg and not extra support at 104kg. If your household has that kind of gap, the 100-night trial is the only honest test — Pure Pro cannot run two spring jobs. More on matching firmness to body type: firmness by sleep position.
Heat, couples, edges
Cooling is a middle score; support is the high one. Dual Airflow side support and a pocket-spring core beat a foam slab. Bamboo and charcoal are a moisture story, not a fan. James Wright at 86kg / 13st 8lb ran warm in a still Lace Market week with a 13.5 tog and no AC. He did not stew. Emma Thompson at 71kg / 11st 2lb is the hot-sleeper veto — she was more annoyed by firmness than heat. Sarah Mitchell at 62kg / 9st 11lb isolated a partner well enough, then argued with the king ticket.
Edges: I sit to put socks on at 86kg / 13st 8lb and Dual Airflow keeps the corner more honest than Pure’s foam-only edge in the hand. Usable, not a hotel perch. David Patel at 104kg / 16st 5lb sitting was heavier and still fine for a minute — that is edge, not extra support from the 2cm layer. Rotate; do not flip. Motion: two encapsulated layers help. It is not all-foam silent. Couples who hate bounce should still use the 100 nights rather than a diagram. Couples 42kg apart should read Sarah at 62kg and David at 104kg as two different jobs on the same 3,000-spring badge.
Durability and care
- Rotate head-to-foot once a month for the first 12 months, then every three. OTTY’s own FAQ. Do not flip — the embroidered cover and Airflow sides are single-sided.
- Protector during the 100 nights. Do not steam-clean the foams. Unbox within OTTY’s window or you can void terms.
- CertiPUR / Europur on the foam. FIRA for UK fire regulations. Neither certificate stops body impressions at year four if you never rotate.
The 10-year warranty covers manufacturing defects, not “the 2cm coils feel less pingy than month one.”
Unboxing and the first week
Pure Pro arrives vacuum-rolled. OTTY’s live page sells free premium two-person delivery as standard — useful, because a 27cm king box is still awkward on a Lace Market stair. Room-of-choice and old-mattress removal are extras at checkout. You pick a date; the morning of, they send a two-hour slot. A single can be a one-person lift. Double and up want two people who still like each other at the half-landing. Cut the wrap on the bed base. Give it 24–72 hours before you decide 7/10 is wrong — the first night on a half-expanded hybrid is a useless test. Open a window for the new-foam smell.
Wait until it is roughly full height before fighting fitted sheets. The picker already printed 27cm. Extra-deep pockets from night one save you a 2am corner pop.
Bed base and sheets
OTTY is happy on divans, slatted frames, adjustable bases, and platforms. They prefer slats for airflow. They do not offer a guarantee on steel bed frames with thin steel supports — sagging risk, their words. Keep slat gaps around 7cm or less. A tired sprung base will make a 27cm hybrid feel cheaper than it is. Floor use is a last resort for a week, not a five-year plan.
Sheets: treat it as 27cm class. Ordinary 25cm fitted sheets usually ping off once a protector is on — Rachel Adams at 68kg / 10st 10lb found that on the Nottingham king. Start at extra-deep 35cm pockets. That is the tax versus a 25cm Pure if your linen cupboard is already full. Add a protector for the trial; do not glue it down.

OTTY is a boxed brand. You will not get a Bensons aisle the way you do with Eve. Ten minutes on a concession bed, if you find one, still will not show Sarah Mitchell at 62kg / 9st 11lb arguing with the king ticket, or David Patel at 104kg / 16st 5lb deciding the extra thousand 2cm coils were optional. Buy from OTTY if you want OTTY’s 100 nights in writing.
UK sizes and prices (August 2026)
OTTY advertised Pure Pro from £539.99 including VAT when we checked — that is the single. Size tickets below were on the live UK picker the same day. The from-price is not a king promise. Always open the size picker. Prices last checked .
| Size | Dimensions | On otty.com? | Ticket (5 September 2026) |
|---|---|---|---|
| Single | 90 × 190 × 27cm | Yes | £539.99 — the from-price. About £15 above Pure’s single. |
| Small double | 120 × 190 × 27cm | Yes — actually sold | £699.99. Pure’s small double was £624.99. This size is a reason to stay if you need 4ft. |
| Double | 135 × 190 × 27cm | Yes | £749.99. Pure’s double was £649.99 — a £100 jump, not £15. |
| King | 150 × 200 × 27cm | Yes | £824.99. Pure king £749.99. This is the ticket Sarah Mitchell at 62kg / 9st 11lb argued with. |
| Super king | 180 × 200 × 27cm | Yes | £924.99. Pure super king £849.99. Two-person lift. Extra-deep sheets. |
| EU Double / EU King / Emperor | 140 × 200 / 160 × 200 / 200 × 200 | No | Not on this picker. Pure still lists them. Rachel Adams at 68kg / 10st 10lb — her skip. |
The live banner that day read 8% off orders over £400, code DREAMY26. Thresholds move. If you buy away from OTTY, confirm the trial is still 100 nights before you chase twenty pounds.

Pure Pro vs Pure
Same charcoal story, different spring count and a different picker. Pure is 25cm, 6.5/10, up to 2,000 × 16cm, from £524.99, and it still sells EU sizes and Emperor. This is 27cm, 7/10, the extra 1,000 × 2cm layer, from £539.99. The from-price gap is about £15. King and super king are the honest gap. OTTY Pure Hybrid review.
| Pure Pro | Pure | |
|---|---|---|
| Type / depth | 27cm hybrid · up to 3,000 springs | 25cm hybrid · up to 2,000 × 16cm |
| Feel | 7/10 · 2cm comfort springs then the tall unit | 6.5/10 · charcoal foam then the tall unit |

| King ticket (5 September 2026) | £824.99 | £749.99 |

Pure Pro vs Pure+
Pure+ is the taller, softer dual-spring OTTY: 28cm, 5.5/10, up to 4,000 springs, from £599.99. Emma Thompson at 71kg / 11st 2lb wanted that. This model still sells a small double; Pure+ is the one that skips 4ft. OTTY Pure+ Hybrid review.
| Pure Pro | Pure+ | |
|---|---|---|
| Springs / depth | Up to 3,000 · 27cm · 2cm layer on a 16cm unit | Up to 4,000 · 28cm · two spring units |
| Firmness | 7/10 medium-firm | 5.5/10 medium — softest current boxed OTTY |
| Small double | Sold | Not available — Pure+ skips 4ft |
| When it is enough | Charcoal plus a thin comfort-spring layer, still 7/10 | Side sleeper at 71kg who wanted the soft flagship and extra-deep sheets — Emma’s case |
| Advertised from (5 September 2026) | £539.99 | £599.99 |
Pure Pro vs Original
Original is still the OTTY most people should try: 25cm, 7/10, knitted cover, up to 2,000 × 16cm, from £499.99. Same printed firmness as this model, no charcoal stack, no 2cm layer. David Patel at 104kg / 16st 5lb — his mattress. Climb only if you already wanted those two extras. More springs is not automatically more support at his weight. OTTY Original Hybrid review.
Pure Pro vs Nectar Premier Hybrid (different brand, same idea)
Both put a short coil layer over a taller pocket-spring unit. Nectar calls them micro-springs; OTTY calls them 2cm comfort springs. Nectar is 28cm, 7/10, from £549, 365 nights, Forever Warranty, no small double. OTTY is 27cm, 7/10, from £539.99, 100 nights, 10 years, small double sold. Different trials. Different owners. Nectar Premier Hybrid review.
| OTTY Pure Pro | Nectar Premier Hybrid | |
|---|---|---|
| Core | 1,000 × 2cm over 2,000 × 16cm · charcoal foam | Micro-springs over pocket springs · 8-layer Nectar stack |
| Depth / feel | 27cm · 7/10 | 28cm · 7/10 |
| Small double | Sold | Not listed |
| Trial / warranty | 100 nights · 10 years | 365 nights · Forever Warranty (defects) |
| Advertised from | £539.99 | £549 |
Short coils over tall coils is a ten-minute feel difference either brand will sell you. The trial length and the 4ft frame are the practical split. OTTY if you need a small double and 100 nights is enough. Nectar if you want a year to decide and you do not need 120 × 190cm.
Better alternatives (if Pure Pro is the wrong job)
- OTTY Pure Hybrid — charcoal without the 2cm layer, 25cm, 6.5/10, and a wider size range including EU and Emperor. The better buy if the from-price flattered this one or your frame is continental.
- OTTY Pure+ Hybrid — 28cm, 5.5/10, up to 4,000 springs. Emma Thompson at 71kg / 11st 2lb — her mattress. Skip 4ft.
- Which OTTY should I buy? — the six current UK boxed hybrids, scored and linked. Includes Aura, Original, and Extra Firm.
- OTTY Original Hybrid — 7/10, no charcoal stack, from £499.99. David Patel at 104kg / 16st 5lb — his skip. The OTTY most people should try first.
- Nectar Premier Hybrid — different brand, same dual-spring idea, 365 nights. Buy it for the year, not for a small double.
OTTY Pure Pro Hybrid FAQ
Final verdict
I would buy this for someone who already wanted Pure’s charcoal and can feel the 2cm comfort-spring layer with a thumb, on OTTY’s own 100 nights, preferably after DREAMY26 or whatever banner is live has knocked the size ticket about. I am 86kg / 13st 8lb — the lead reviewer, not the 104kg tester. I would not buy it because the from-price is only £15 above Pure. That gap is a single. Kings and super kings jump hard. I would not buy it for Rachel Adams at 68kg / 10st 10lb on an Emperor. I would not buy it for Emma Thompson at 71kg / 11st 2lb if she actually wanted 5.5/10. I would not buy it for David Patel at 104kg / 16st 5lb if Original already felt like enough mattress — more springs is not automatically more support at his weight. I would not buy it for Sarah Mitchell at 62kg / 9st 11lb hoping extra springs become extra hug. Three of five testers would not buy it. The extra thousand short coils are the product. The narrower picker and the king till are the product too. The kilogram figures are why.
Our score: 4.2/5. Keep the receipt. Use the 100 nights.

About the tester

James Wright
Lead Product Tester · Former Quality Manager, Silentnight Beds
James spent 10 years in Silentnight quality control. He is 86kg / 13st 8lb — the lead reviewer, not the 104kg tester — a mixed back/side sleeper. He reads a hybrid by which coil answers first. He slept on a king Pure Pro in a Nottingham Lace Market conversion. He would buy it for someone who wanted Pure’s charcoal and the 2cm comfort-spring layer without Pure+ height — not for Rachel’s Emperor frame, not as an automatic upgrade from Original, and not because 3,000 springs automatically supported David Patel at 104kg / 16st 5lb or hugged Sarah Mitchell at 62kg / 9st 11lb.
