Layer Details
- Cover. A breathable Belgian damask fabric top cover, which means air can move through the sleep surface rather than being trapped against you. That helps keep the mattress feeling fresh and a little cooler.
- Comfort Fillings. Soft cotton combined with Hypnos' eOlus fibres for total body cushioning. In practice this gives a gentle, natural-feeling surface that contours without the slow sink of memory foam.
- Support System. ReActive 6-Turn pocket springs, with six turns per spring, engineered for total spinal and body support. Each spring moves independently, which means less partner disturbance and support that follows the shape of your body.

- 90cm of width each: Two people sharing get 90cm each, which means a restless partner is far enough away that their fidgeting barely registers.
- Independent springs across a huge surface: The ReActive 6-Turn pocket springs respond individually, so movement on one side of this 180cm width stays on that side.
- Room for midnight visitors: When a child pads in at 3am, or the dog claims a corner, everyone still has a workable share of the bed.
- Cool sleeping at scale: Cotton fillings and the breathable damask cover mean two bodies, and sometimes more, are less likely to build up heat across the night.
- Bigger than a UK king where it counts: The UK super king is 30cm wider than the UK king at the same length, and that extra width is where shared sleep improves.
This size suits you if...
You share the bed every night and want the most space a standard UK size offers, your partner is restless enough that distance matters more than any comfort layer, or children and pets regularly join you and you'd rather plan for it than fight it. Your bedroom should be at least 3m x 2.9m, and ideally closer to 3.5m x 3.2m.
Consider another size if...
Your bedroom is under our suggested 3m x 2.9m minimum, or the bed would dominate the room. We'd recommend the UK king instead: it's 30cm narrower at the same length, and we suggest at least 2.7m x 2.9m for it.

How much space do two people get on the Hypnos Cotton Comfort super king?
90cm each for two people sharing, which is the same width per person as a UK single. In practice that means you can stretch out, change position or sleep starfished without crossing into your partner's half. Combined with pocket springs that compress individually, it's the size where two very different sleepers stop compromising.
What size room do I need for the Hypnos Cotton Comfort in a UK super king?
We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling right. That allows walking space on both sides and room for bedside tables. Before ordering, check the door swing and any tight landing turns too; at 180 x 200cm this is a big item to move through a house.
Is the UK super king worth it over the UK king for this mattress?
If your room takes it, usually yes. The UK super king is 30cm wider than the UK king and the same length, and all of that extra width goes to the two of you. For couples where one person sleeps lightly, the extra distance does more than any filling could. In a smaller room, though, the UK king is the sensible call.
Is the super king size good for sharing with children or pets?
It's the size we'd point families to. At 180cm wide there's enough surface that a wandering toddler or a large dog doesn't push either adult to the edge, and the independent pocket springs mean small bodies climbing in cause less of a ripple. The breathable cotton fillings also help when there are extra warm bodies under the duvet.
Does the Hypnos Cotton Comfort feel different in the super king?
The medium feel, 26cm depth and cotton comfort layers are identical across every size. What changes is how well the construction shows: with 180cm of width, the individually moving springs have more room to isolate one sleeper's movement from the other, so partner disturbance is at its lowest in this size.
