Layer Details
- Cover. A blend of cotton, viscose and damask fibres with a chemical-free fire retardant treatment, which means it meets fire safety standards while staying kind to your skin. It's a soft, traditional-feeling surface rather than a synthetic one.
- Comfort layer. Solotex padding made from recycled plastic sits just beneath the cover. It creates the cushioned initial feel you notice when you first lie down.
- Wool filling. British wool, certified to the Responsible Wool Standard, acts as a natural insulator. Its breathable structure adjusts to your body temperature, so you're less likely to wake up too hot or too cold.
- Cotton filling. Natural cotton fibres wick away moisture and help regulate temperature through the night. If you're a hot sleeper, this layer works alongside the wool to keep things fresh.
- Support system. A core of 1200 ReActivePro six-turn pocket springs responds to each part of your body independently, which means your partner's movements are less likely to disturb you. Three rows of extra durable springs around the border firm up the edges.

- Real space for two: At 75cm each for two people sharing, you can both change position without the other person becoming part of the manoeuvre.
- Less disturbance on different schedules: The 1200 six-turn pocket springs respond to each body independently, which means a 5am alarm on one side is less likely to wake the other.
- Length for taller sleepers: The 200cm length is 10cm longer than the UK double, a difference anyone approaching six foot feels immediately.
- Usable edges across the full width: Three rows of firmer border springs mean you can sleep right at your own edge, so the whole 150cm width is genuinely yours to use.
- Breathable at a size where heat builds: Two people generate more warmth than one, and the British wool and cotton fillings wick moisture rather than trapping it between you.
This size suits you if...
You share the bed every night and a UK double leaves you both sleeping in fixed positions, or one of you gets up hours before the other and wants the springs to keep that quiet. It also suits couples where one partner is tall enough that 190cm beds mean feet over the end, or where the dog has claimed a permanent patch and refuses to negotiate.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest for a UK king, or you sleep alone. We'd recommend the UK double of this mattress instead, allowing at least 2.6m x 2.8m for the room.

Is a UK king big enough for a couple on this Hypnos mattress?
Comfortably, for most. You get 75cm each for two people sharing, and the Denhome's pocket springs move independently under each of you, so one person shifting or getting up early transmits less across the mattress. If you're both broad or share with children or pets regularly, the UK super king adds another 30cm of width.
Will the Hypnos Denhome UK king suit a tall sleeper?
This is one of the better reasons to pick it. At 200cm, the UK king is 10cm longer than the UK double, which matters once someone is near six foot. The firmer border springs also help here: you can use the full length without the foot end feeling soft or unsupported.
What room size do I need for the Denhome in a UK king?
We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable once wardrobes and bedside tables are in. New build master bedrooms can be tighter than they first appear, so measure with furniture in mind. If the room won't stretch, the UK double needs a little less, at 2.6m x 2.8m.
Should I get the Denhome in a UK king or a UK super king?
The UK king is 30cm narrower than the UK super king; the two are the same length, so this is purely a width decision. Go super king if pets or children join you regularly and the room allows at least 3m x 2.9m. For most couples, the UK king is the sensible middle ground.
