Layer Details
- Cotton sleep surface. A responsibly sourced cotton sleep surface that is naturally fire-resistant. It's the layer you'll actually feel, soft and breathable against the skin.
- Cotton. A cotton filling that helps regulate body temperature, which means less overheating on warm nights. It also adds natural comfort and a touch of extra support.
- Solotex™. A recycled fibre that is fully breathable, so air can move through the mattress rather than getting trapped. A quietly sustainable choice too.
- ReActive™ 6-Turn Pocket Springs. Each spring has six turns and works independently, sensing the support you and your partner need and spreading downward pressure smoothly. In practice, that means consistent spinal support and less partner disturbance.
Layer details from mattressnextday.co.uk product page, September 2026.
- 90cm each for two sharers: With 90cm each for two people sharing, a fidgeting partner is far enough away that their movement barely registers.
- Springs that keep movement local: Hypnos's ReActive 6-turn pocket springs respond independently under each sleeper, which means motion on one side is less likely to travel across all that width.
- Firm support across the whole surface: The firm feel holds its shape at this scale, so a child climbing in at 3am doesn't tip either adult into a dip.
- Breathable fillings for a big shared bed: Cotton and Solotex recycled fibre let air move through, useful when three bodies, or two plus a dog, share one mattress.
- Fills a large master properly: In a period property or generous new build master, a UK king can look undersized; the UK super king's 6ft width sits in proportion.
This size suits you if...
You share every night and want distance from a partner who turns over a lot, your children or pets regularly end up in the bed and you'd rather everyone kept a fair share, or your master bedroom is large enough that anything smaller would look lost. Allow at least 3m x 2.9m of floor space, and closer to 3.5m x 3.2m to move around it comfortably.
Consider another size if...
Your bedroom is under our suggested 3m x 2.9m minimum, or the mattress won't make the turn on your stairs or landing. We'd recommend the UK king instead: it's 30cm narrower, the same length, and we suggest at least 2.7m x 2.9m for it.

How much space does each person get on a super king Hypnos Premier Ortho Superb?
You get 90cm each for two people sharing. Combined with the ReActive 6-turn pocket springs, which work independently under each sleeper, that distance means a partner who shifts position through the night is much easier to ignore than on a smaller size.
Is the Hypnos Premier Ortho Superb super king a good choice for families sharing the bed?
It's one of the better fits for it. The 180cm width leaves room when a child wanders in during the night, and the firm feel keeps the surface stable rather than letting an extra body create a dip. Lightweight side sleepers may still find the firmness a little unforgiving, child or not.
How much bigger is the super king than the UK king in this mattress?
The UK super king is 30cm wider than the UK king, and the two are the same length at 200cm. All of that extra width goes into sleeping space, so it's the difference you'd choose for a restless partner or regular company from children or pets.
Will the Hypnos Premier Ortho Superb super king fit my bedroom?
We suggest a room of at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable once you add bedside tables and space to walk around. Check door swings and any tight landing turns before ordering, as a 180 x 200cm mattress is an awkward carry upstairs.
Do hot sleepers cope with sharing this mattress in a super king?
Better than you might expect. The cotton and Solotex recycled fibre fillings are breathable, so heat can escape rather than build up, and the 90cm each for two sharers means you're not pressed against a warm partner. If you run very hot, the extra distance genuinely helps.
