Cover
A QuickRefresh cover with SmartCool technology, which means the surface is designed to feel cooler to the touch. It sits on top of the foam and can be freshened up more easily than a fixed cover.
Filling
TEMPUR Advanced Material, the slow-response foam the brand is known for. It contours closely to your body, which means excellent pressure relief but less of the springy pushback you'd get from a hybrid.

Key benefits
- Real stretching room for one: At 120cm wide, you can change position, starfish or curl up without reaching the edge, useful on a foam that cradles you closely.
- Fits rooms a double crowds: It's 15cm narrower than a UK double, which can be the difference between a door that clears the bed and one that doesn't.
- Soft feel suits a solo side sleeper: The Soft rating lets hips and shoulders sink in, and sleeping alone means no compromise with a partner who prefers firmer support.
- Copes with occasional sharing: For a guest room used by couples a few weekends a year, the width is workable for two, though we wouldn't suggest it nightly.
- Standard 4ft size: Small double frames and bedding are widely stocked in the UK, so kitting out this size is straightforward.
This size suits you if...
You sleep alone and have outgrown a UK single but your room can't take a full double, you're furnishing a box room, loft conversion or studio where every centimetre of width counts, or you want a guest bed that handles a visiting couple occasionally. Allow at least 2.4m x 2.8m of floor space and the UK small double sits comfortably.
Consider another size if...
You share the bed every night, or with 30cm less width than a UK king you'd feel hemmed in as a spreading solo sleeper. For nightly couples we'd recommend the UK double of this mattress instead.

FAQ's
Is a small double Tempur big enough for two adults?
For occasional nights, yes. At 120cm wide the UK small double can take two people, and the slow-response foam absorbs movement well, so you won't feel every turn. For couples sharing every night it's tight, and the UK double gives 15cm more width. Think guest room rather than main bedroom for two.
What room size do I need for the Tempur Pro SmartCool Soft small double?
We suggest allowing at least 2.4m x 2.8m. That leaves enough space to walk round the bed and open drawers or a wardrobe. In a loft conversion or box room, measure where the walls slope or the door swings, since the 120cm width is often what decides the layout.
How much wider is a 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 this mattress that extra width is worth having: the Soft TEMPUR material contours where you settle, so more room to move means you feel the pressure relief rather than the edge.
Is this size a good upgrade for a teenager?
Often, yes. A teenager who has outgrown a UK single gets meaningful extra width without losing the floor space a full double would take. One caution: this is a premium slow-response foam with a Soft feel, a considerable spend for a growing sleeper, so make sure the cradling feel suits them first.
What bedding fits the small double version?
Use small double, 4ft, fitted sheets for the 120 x 190cm mattress. Most people pair them with a standard double duvet, which drapes generously over the narrower base. It's a standard UK size, so sheets and protectors are easy to find, and the QuickRefresh cover can be removed for freshening up underneath.
