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.

- 75cm each for couples: Two people sharing get 75cm of width apiece, so a partner who props pillows or shifts position through the night has room to do it without crowding you.
- Springs plus space equals quieter nights: The pocket springs respond individually to each body, and at 150cm wide there's enough distance between you that an early alarm on one side barely registers on the other.
- Length for taller sleepers: At 200cm, the UK king is 10cm longer than the UK double, which anyone approaching six foot will feel at their ankles every night.
- Firm support that holds across the full width: The natural latex and 10-turn springs keep the surface consistent edge to edge, useful when two different body weights share one mattress.
- A long-term size choice: Double-sided construction means the mattress can be flipped to wear evenly, sensible on a size most couples keep for a decade or more.
This size suits you if...
You share the bed every night and a UK double has started to feel cramped, one of you is on a different schedule and you want their comings and goings to fade into the background, or someone in the bed is nudging six foot and needs the 200cm length. The firm feel suits heavier sleepers and back sleepers particularly well at this width.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest for a UK king, especially once wardrobes are in. The UK double would suit you better, needing around 2.6m x 2.8m and still giving a couple a proper night's sleep.

Is the Hypnos Organics 6 UK king big enough for a couple?
Comfortably, for most. At 150 x 200cm you get 75cm of width each, noticeably more personal space than a UK double allows. Combined with pocket springs that move independently, it means one of you can turn over or get up early without dragging the other awake. Couples who want still more room should look at the UK super king.
What size room do I need for a UK king mattress?
We suggest at least 2.7m x 2.9m for a UK king, with 3.2m x 3.2m feeling comfortable once you add bedside tables and wardrobes. New build master bedrooms can be tighter than they first appear, so measure with the furniture in mind, and remember you'll want space around the bed to flip this mattress.
Is the UK king Hypnos Organics 6 long enough if I'm over six foot?
It's one of the better options. The UK king runs 200cm long, which is 10cm longer than the UK single, UK small double and UK double. That extra length is usually the difference between feet on the mattress and feet hanging off it. If you need more width as well, the UK super king matches the same 200cm length.
Can one person flip the Hypnos Organics 6 in a king size?
We'd advise against trying alone. The mattress is 31cm deep with dense natural fillings, and at 150 x 200cm it's an awkward, heavy object for one person. Since it's double-sided and designed to be flipped regularly, plan for two people each time, or size down if that's not practical in your household.
Should I choose the UK king or UK super king in this mattress?
The UK king suits most couples: real personal space without dominating the room. The UK super king is 30cm wider at the same length, and we suggest at least 3m x 2.9m of floor space for it. If a dog routinely claims part of the bed, or you simply want maximum separation, that extra width is where the money goes.
