Layer Details
- Knitted Cover. A soft knitted cover that is breathable, which means heat can escape rather than gathering at the surface. It helps keep you at an even temperature all night.
- Cool Gel Memory Foam. A thick layer of cool gel-infused memory foam that gives you the contouring and pressure relief of standard memory foam. The gel infusion helps maintain optimum body temperature, so you sink in without overheating.
- Pocket Springs. The foundation is over 800 individually wrapped pocket springs, each moving independently. That means bespoke, targeted support for each part of your body rather than a one-size response.

- Space to spread out alone: At 120cm wide, this size is 30cm wider than the UK single, which means a solo sleeper can sprawl without the mattress dominating the room.
- Fits where a double cannot: It is 15cm narrower than the UK double, often the difference between a door that clears the bed frame and one that does not.
- Cool gel across the whole surface: The gel-infused memory foam keeps its temperature control at this width, so a solo sleeper who moves around at night stays on cool foam wherever they land.
- Pocket springs for occasional sharing: Over 800 individually wrapped springs move independently, so a couple sharing for a weekend stay will feel less of each other's movement than on a basic sprung guest bed.
- Easy to dress: 4ft is a standard UK size, so small double fitted sheets are simple to find, and a standard double duvet drapes generously over it.
This size suits you if...
You sleep alone, run warm at night, and have outgrown a UK single but your room cannot take a full double. Or you need a compact double for a box room, loft conversion or holiday let second bedroom, where a couple might share occasionally but nobody sleeps two-up every night.
Consider another size if...
You share the bed every night and want proper space each. The Coolflex Hybrid ICE in a UK double is 15cm wider and the same length; allow at least 2.6m x 2.8m of floor space for it.

How big is the Coolflex Hybrid ICE small double?
It measures 120 x 190cm, which is 4ft x 6ft 3in. That makes it 30cm wider than the UK single and 15cm narrower than the UK double, with all three sharing the same length. We suggest a room of at least 2.4m x 2.8m to leave walking space around it.
Is the Coolflex Hybrid ICE small double big enough for a couple?
For occasional nights, yes. The pocket springs respond to each sleeper separately, so a visiting couple will sleep reasonably undisturbed. For every night, 120cm is a squeeze for two adults, and the medium firm feel means neither of you can retreat into a soft edge. Couples sharing nightly should look at the UK double or UK king.
Will the Coolflex Hybrid ICE small double fit in a box room?
Usually, and this is the size's main strength. We suggest a minimum room of 2.4m x 2.8m. Being 15cm narrower than the UK double, it often clears doorways and leaves wardrobe access in rooms where a 4ft 6in bed would block both. Measure your room, then check against the mattress's 120 x 190cm footprint.
What bedding does the small double Coolflex Hybrid ICE need?
Small double (4ft) fitted sheets, which are a standard UK size and easy to buy. A standard double duvet suits it well, hanging a little further down each side than it would on a UK double, which is no bad thing on cold nights. The mattress itself is hypoallergenic, useful if guests have allergies.
Should a teenager have a small double or stick with a single?
If the room can spare the width, the small double is a sensible upgrade: 30cm wider than the UK single and the same length, so it takes more floor space side to side but no more end to end. The medium firm feel and cooling foam suit a growing sleeper who runs warm. In a very narrow room, the UK single still makes more sense.
