Layer Details
- Sleep surface. An organic wool and cotton sleep surface that's naturally breathable. This is the layer you'll feel first, soft and temperature-regulating against your skin.
- Natural latex layer. Natural latex relieves pressure at your hips and shoulders, which means less tossing and turning. It does this without any synthetic foam.
- Moisture-wicking layer. A natural blanket of cotton, hemp and flax draws moisture away from you as you sleep. Helpful if you run warm at night.
- Pocket springs. Hypnos' ReActivePro 10-turn pocket springs respond individually to the shape of your body, encouraging natural spinal alignment. Each spring moves on its own, so your partner's movement is less likely to disturb you.
- Wool and silk blend. Layer upon layer of British lambswool blended with ethically farmed peace silk. These natural fillings add cushioning and help regulate temperature through the seasons.

- Genuine distance from a restless partner: At 90cm each for two people sharing, movement on the other side happens far enough away that the ReActivePro pocket springs rarely need to absorb it.
- Space for the whole household: When children pad through at 3am, the extra 30cm over a UK king is often the difference between everyone sleeping and someone decamping to the sofa.
- A firm surface that spreads the load: The firm latex-over-spring build stays supportive across the full 180cm width, so an extra small body climbing in doesn't create a dip everyone rolls into.
- Natural fillings across a bigger surface: Wool, cotton, hemp and flax wick moisture over the whole 180 x 200cm sleep surface, which matters more when three or four of you are generating heat.
- Double-sided wear at family scale: A flippable 31cm mattress wears more evenly than a one-sided one, useful when a super king takes nightly traffic from more than two sleepers.
This size suits you if...
You share the bed every night and want enough width that a fidgeting partner effectively sleeps in a different postcode, your children or a large dog treat the bed as communal territory, or your master bedroom is generous enough that a UK king would look and feel undersized. It helps if there are two of you fit enough to flip a heavy 31cm mattress regularly.
Consider another size if...
Your bedroom is smaller than the 3m x 2.9m we suggest as a minimum, or flipping a mattress this large isn't realistic for you. We'd recommend the UK king instead, which is 30cm narrower, the same length, and needs at least 2.7m x 2.9m.

What size room do I need for the Hypnos Organics 6 super king?
We suggest a minimum of 3m x 2.9m, which leaves walking space around a 180 x 200cm mattress. Before ordering, check door swing and the turn on your landing too: this is a 31cm-deep mattress in the largest standard UK size, so the route into the room deserves as much thought as the room itself.
Is the Hypnos Organics 6 hard to flip in a super king?
It's the most demanding size of this mattress to turn. The Organics 6 is double-sided and 31cm deep, and flipping it regularly is how you get even wear from it. At 180 x 200cm that's firmly a two-person job, so if you live alone or have a bad back, factor that in before choosing this size.
Will a restless partner still disturb me on a super king Hypnos Organics 6?
Less than on any smaller size. The pocket springs move individually, which limits how far motion travels, and with 90cm each for two people sharing there's simply more mattress between you and the fidgeting. Distance does a lot of the work here; the springs handle whatever crosses it.
Should I buy the Hypnos Organics 6 in a UK king or a UK super king?
The UK super king is 30cm wider than the UK king and the same length. If children or pets join you regularly, or one of you sleeps restlessly, that extra width is what you're paying for. If your room is under the 3m x 2.9m we suggest for a super king, the UK king needs at least 2.7m x 2.9m and would suit you better.
Is a super king big enough for sharing with young children?
It's the size we'd point families to. At 180cm wide, two adults keep a reasonable share even with a child stretched sideways between them, and the firm surface doesn't let a small extra body sink a hollow into the middle. No mattress makes co-sleeping tidy, but this size makes it survivable.
