Layer Details
- Cover. A QuickRefresh™ cover with SmartCool™ technology, designed to keep the sleep surface feeling cooler. This tackles the heat retention that dense foam mattresses are sometimes known for.
- Filling. TEMPUR® Advanced Material, a slow-responding foam that moulds to your body under weight and warmth. This gives close pressure relief, which means less push-back on hips and shoulders than a springier surface.

- Real space for one sleeper: At 120cm across, you get 30cm more width than a UK single, which means room to shift position without waking against an edge as the foam contours around you.
- Fits compact double bedrooms: The UK small double is 15cm narrower than a UK double, often the difference between a door that clears the frame and one that doesn't.
- Contouring suits solo sleeping: TEMPUR Advanced Material moulds to one body's shape without a partner's movement to work around, so a lone sleeper feels the pressure relief at its best.
- Cooler surface in a smaller room: The SmartCool cover is designed to keep the sleep surface cooler, useful in box rooms and lofts where air doesn't circulate as freely.
- Manageable for occasional guest use: Couples can share 120cm for a few weekends a year, and the low-motion foam means one guest turning over is less likely to disturb the other.
This size suits you if...
You sleep alone, have outgrown a UK single and want the extra width to stretch out on a contouring surface; your bedroom, loft conversion or studio can't take a UK double without losing walking space; or you're furnishing a guest room or holiday let where couples stay occasionally rather than nightly.
Consider another size if...
You share the bed every night, because 120cm split between two adults feels tight on a foam that cradles rather than lets you slide. We'd recommend the UK double, or ideally the UK king, instead.

Is a UK small double Tempur Pro SmartCool big enough for a couple?
For occasional nights, yes. The slow-responding TEMPUR foam absorbs movement well, so a partner turning over is less disruptive than on a springier surface. For every night, 120cm is a squeeze for two adults, and we'd point regular couples towards the UK double or UK king of this mattress.
What room size do I need for the Tempur Pro SmartCool in a small double?
We suggest allowing at least 2.4m x 2.8m. That gives you space to walk around the bed and open drawers or wardrobes without shuffling sideways. The UK small double is 15cm narrower than a UK double, which is often exactly what a box room or loft conversion needs.
How much wider is the UK small double than a single?
The UK small double is 30cm wider than the UK single, at 120 x 190cm, or 4ft x 6ft 3in. On a contouring foam like this, that extra width matters: you can change position freely rather than settling into one spot for the night.
Is the small double a good size for a teenager?
Often, yes. It suits a teenager who has outgrown a UK single but whose room can't spare the floor space a UK double takes. The medium feel is balanced enough for most sleeping positions, though it is a premium spend for a bed that may be replaced within a few years.
Where can I buy the Tempur Pro SmartCool Medium in a small double?
Availability shifts, so the most reliable answer is the live comparison table on this page, where prices are updated as retailers change them. The UK small double is a standard 4ft size, so frames and fitted sheets are easy to find; a standard double duvet works on top.
