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.
Layer details from otty.com product page, September 2026.
- 15cm more width than a UK double: The UK king is 15cm wider than the UK double, which means each of you gains elbow room you'll notice on the very first night.
- Springs that keep early starts quiet: The encapsulated pocket springs minimise motion transfer, so if one of you gets up hours before the other, the movement stays on their side.
- Extra length for taller sleepers: At 200cm long, the UK king adds 10cm over a double, a genuine relief for anyone approaching six foot.
- Cooling shared fairly: Two bodies generate more heat than one, and the Ice cover's cooling fibres and heat-regulating foam work hardest in a shared bed.
- Usable width right to the edge: The airflow side supports give an edge-to-edge sleeping surface, so all 150cm is genuinely sleepable rather than a soft roll-off zone.
This size suits you if...
You share the bed every night and a double no longer feels like enough space for two, or one of you keeps different hours and their alarm shouldn't be your alarm. It also suits couples where one partner is tall, since the 200cm length removes the feet-off-the-end problem, or where a dog has quietly claimed a portion of the mattress and 135cm stopped being enough some time ago.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest as a minimum, or you sleep alone and would rarely use the width. In a smaller room, the UK double of this mattress would suit you better.

Is the Otty Original Ice Hybrid in a UK king big enough for a couple?
Yes, comfortably for most. At 150cm wide it gives 75cm each for two people sharing, and the edge-to-edge side supports mean the outer inches stay supportive rather than collapsing. If one of you sprawls, or a pet joins in, sizing up to the UK super king is the next step.
How much bigger is the UK king than a double?
The UK king is 15cm wider than the UK double and 10cm longer too, at 150 x 200cm against 135 x 190cm. That width difference sounds modest on paper, but split between two sleepers it's the gap between touching elbows and settling into your own space.
Will the UK king Otty Ice Hybrid stop me feeling my partner move?
It helps on two fronts. The encapsulated pocket springs move independently, which minimises motion transfer, and the extra width of a UK king means you're simply further from the disturbance. If one of you leaves for work hours before the other, that combination makes a real difference.
What room size do I need for a UK king bed?
We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m the comfortable target. New build master bedrooms can feel tighter than the floor plan suggests once wardrobes go in, so measure your walkable space with furniture in place before committing to this size.
Is the UK king long enough for someone over six foot?
At 200cm, the UK king gives a tall sleeper meaningful clearance, and it's 10cm longer than a UK double. For many couples with one tall partner, that extra length is the real upgrade, with the added width a welcome bonus. The UK super king is the same 200cm length, so sizing up buys width, not more legroom.
