Layer Details
- OTTY Ice® Cover. A thick knit cover with cooling fibres, which means the surface actively helps regulate your temperature rather than trapping heat. It's removable and machine washable, so spills aren't a disaster.
- Heat Regulating Memory Foam. Memory foam that contours to you while its heat-regulating technology works to keep you at a comfortable temperature. This tackles the classic memory foam complaint of sleeping warm.
- High Density Support Foam. A layer of Reflex foam sitting above the springs, which means you feel cushioned comfort with extra support rather than the springs directly.
- 16cm Encapsulated Pocket Springs. Up to 2,000 encapsulated pocket springs give the mattress its medium-firm feel and the bulk of its support. Because each spring moves independently, motion transfer is kept to a minimum.
- Side Support. Airflow technology around the edges creates an edge-to-edge sleeping surface, which means you can sit or sleep near the side without it collapsing. It also helps air move through the mattress.
- High Density Base Foam. A solid foam foundation that keeps everything above it stable. It's there to help the mattress stand the test of time.

- 90cm each, every night: Two people sharing get 90cm apiece, which means you can both change position freely without ever negotiating for space.
- Distance plus springs against restlessness: The encapsulated pocket springs already limit motion transfer, and at this width there's simply more mattress between you and a fidgeting partner.
- Cooling that matters more when sharing: Two bodies generate more heat than one, so the Ice cover's cooling fibres do more useful work here than in a smaller size.
- Edge-to-edge at full width: The airflow side supports mean all 180cm is usable sleeping surface, helpful when a child climbs in and everyone shuffles outwards.
- Fills a large master properly: In a big bedroom a smaller bed can look lost; at 6ft x 6ft 6in this size sits in proportion with the room.
This size suits you if...
You share every night and want the maximum space a standard UK size offers, your partner moves around enough that a UK king still feels crowded, or your bed regularly hosts children or a dog on top of two adults. It also makes sense if you run warm as a couple, since the cooling layers work hardest when two people share.
Consider another size if...
Your bedroom is smaller than the 3m x 2.9m we suggest as a minimum, or you sleep alone. In either case we'd recommend the UK king instead, which is 30cm narrower and far easier to fit and dress.

What room size do I need for a super king Otty Ice Hybrid?
We suggest a room of at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable. That allows walking space on both sides and room for bedside tables. In a tighter room the bed dominates, and you'll be squeezing past it daily, which gets old quickly.
Is the Otty Ice Hybrid super king big enough for co-sleeping with kids?
It's the best standard size for it. Two adults get 90cm each, so when a child wanders in there's genuine room to absorb them, and the edge-to-edge side supports mean whoever ends up near the rim still gets proper support rather than a collapsing edge.
Will the super king Otty Ice Hybrid get up my stairs?
It arrives roll-packed, which helps, but at 180 x 200cm unrolled it's a big item. Check door swings, landing turns and any loft staircase before ordering, because once it's expanded you won't be re-rolling it. Narrow Victorian stairs and awkward half-landings are the usual sticking points.
Does a bigger mattress mean more motion transfer?
No, the opposite in practice. The encapsulated pocket springs isolate movement in every size, but the super king adds sheer distance: with 90cm each, a partner turning over happens further away from you. For genuinely restless sleepers, that width does more than any comfort layer could.
What bedding fits the super king Otty Ice Hybrid?
You'll need super king sheets and a 260 x 220cm duvet. Fewer shops stock this size and it costs a little more than king bedding, so factor that in. The 25cm depth is standard, so most super king fitted sheets will go on without a struggle.
