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 one: At 120cm across, a solo sleeper gets the full width to themselves, which means you can shift position freely without meeting the edge.
- Fits where a UK double will not: The UK small double is 15cm narrower than the UK double, which can be the difference between a door clearing and a room feeling cramped.
- Wool and cotton across the whole surface: The British wool and cotton fillings breathe and wick moisture wherever you lie, useful when one sleeper is using every inch of a 4ft mattress.
- Edges you can actually use: Three rows of firmer border springs support the sides, so sleeping close to the edge in a tighter room still feels secure.
- Occasional two, comfortable one: The 1200 pocket springs respond to each body independently, so a visiting couple can share for a few nights without every movement transferring across.
This size suits you if...
You sleep alone and have outgrown a UK single but your room can't spare the floor space a UK double demands, you're furnishing a loft conversion or box room where 15cm of width decides the layout, or you want a guest bed that couples can share for the odd weekend without it dominating the room.
Consider another size if...
You share the bed every night, since 120cm is a squeeze for two medium-firm sleepers long term. We'd recommend the UK double instead, which is 15cm wider and needs a room of at least 2.6m x 2.8m.

Is the Hypnos Denhome small double big enough for two people?
For occasional nights, yes. The pocket springs respond to each sleeper independently, so a visiting couple sharing a guest room won't disturb each other much. For every night, 120cm of width is tight for two adults. If you share regularly, the UK double gives you 15cm more width and suits rooms of at least 2.6m x 2.8m.
What room size do I need for the Denhome in a UK small double?
We suggest at least 2.4m x 2.8m. That leaves enough clearance to open drawers and walk round the bed without shuffling sideways. If your room is smaller, remember the UK single is 30cm narrower and the same length, and we suggest at least 2.1m x 2.8m for that size.
How big is the Hypnos Denhome small double in feet?
It measures 4ft x 6ft 3in, or 120 x 190cm. That's the standard UK small double size, so frames and 4ft fitted sheets are easy to find. Note it's 10cm shorter than the UK king as well as 30cm narrower, so taller sleepers wanting extra length would need to size up.
Is a small double worth it for one person?
On this mattress, arguably more than most. You get the full 1200-spring count and the wool and cotton fillings entirely to yourself, with 30cm more width than a UK single to spread out in. Given the Denhome is a serious spend, a solo sleeper in a compact room gets the most value from this size.
