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.

- A footprint that leaves room to live: At 90cm wide, this size leaves space for a desk, wardrobe and toy storage in the same room, which matters when the bed can't have the floor to itself.
- Edge support on a narrow bed: Three rows of firmer border springs mean the full 90cm width is usable, so a solo sleeper who drifts to the edge won't feel close to rolling off.
- A build that suits growing sleepers: The medium firm pocket spring support gives children and teens proper spinal alignment as they grow, rather than the soft sink of cheaper foam singles.
- Breathable for small rooms: Wool and cotton fillings wick moisture and regulate temperature, useful in compact bedrooms and loft rooms that run warm in summer.
- The easiest size for two-bed setups: Fitting two singles plus a walkway is realistic where one bigger bed isn't, whether that's siblings sharing or a guest room set up for visiting family.
This size suits you if...
You're buying for one person: a child moving up from a cot bed, a teenager who needs supportive springs through growth spurts, or a solo adult in a compact room. It also makes sense if your spare room doubles as an office and the bed has to share the space, or if you're putting two beds in one room for siblings or guests and need each to take up as little width as possible.
Consider another size if...
You're an adult couple, or a solo sleeper who spreads out and has the floor space to spare. The UK double gives you 45cm more width at the same length; we suggest at least 2.6m x 2.8m of room for it.

What size is the Hypnos Denhome Luxury Comfort in a UK single?
It measures 90 x 190cm, or 3ft x 6ft 3in. That's the standard UK single, so it fits ordinary single frames, and standard single sheets and a 135 x 200cm single duvet will fit without adjustment. We suggest allowing at least 2.1m x 2.8m of floor space around it.
Will the UK single Hypnos Denhome fit a bunk or mid sleeper frame?
The 90 x 190cm footprint matches standard bunk and mid sleeper bases, but the mattress is 30cm deep, which is more than many raised frames allow. Guard rails need to sit well above the sleeping surface, so measure your frame's maximum mattress depth before buying. For younger children on top bunks, a shallower mattress is often the safer choice.
Is the UK single Denhome a good mattress for a child or teenager?
The medium firm feel and 1200 pocket springs give growing bodies consistent support, and the wool and cotton fillings handle warm rooms well. It's a serious spend for a child's room, but a teenager can realistically use it into adulthood, which changes the maths. Lightweight children may find the surface slightly firmer than the medium label suggests.
How much room do I need for a UK single Hypnos Denhome?
We suggest at least 2.1m x 2.8m of floor space. That's our own guidance, allowing enough clearance to walk around the bed and open drawers or wardrobe doors. In practice a UK single fits rooms that no other size can manage, including loft conversions where the bed has to sit under the slope on a narrow strip of full-height floor.
How much smaller is a UK single than a UK double?
The UK single is 45cm narrower than the UK double, and the two are the same length. If you're weighing them up for one adult, the UK double needs a room of at least 2.6m x 2.8m by our guidance, so the decision often comes down to whether your room can absorb that extra width comfortably.
