Layer Details
- Cover. A QuickRefresh™ cover with SmartCool™ technology, designed to help the surface of the mattress feel cooler to the touch. It sits directly against you, so it shapes the first impression of the mattress each night.
- Filling. TEMPUR® Advanced Material, the brand's signature slow-response foam. It softens with body heat and moulds to your shape, which means pressure is spread evenly rather than concentrated at the hips and shoulders.

- Real space for one: At 120cm wide, the UK small double is 30cm wider than the UK single, so a solo adult can stretch out without shifting to a bigger room.
- Fits rooms a double cannot: Being 15cm narrower than the UK double, this size suits box rooms, studio flats and loft conversions where every centimetre of floor space matters.
- Slow-moulding pressure relief across the full width: TEMPUR® Advanced Material moulds to your body wherever you settle, which means a solo sleeper can drift across the 4ft surface and still feel evenly supported.
- Cooler surface in a snug room: Compact bedrooms can run warm, and the SmartCool™ cover is designed to make the sleep surface feel cooler than traditional memory foam.
- Quiet for occasional sharing: The foam's low motion transfer helps when a couple shares this size for guest room weekends, since one person turning over disturbs the other less.
This size suits you if...
You sleep alone and have outgrown a UK single but your room cannot take a full double, or you're furnishing a guest room where couples stay a few weekends a year rather than every night. It also fits a downsizing move, where the bed has to suit the new room's dimensions. Allow at least 2.4m x 2.8m of floor space, our suggestion rather than Tempur's.
Consider another size if...
You share the bed every night, because 120cm is a squeeze for two adults long term. We'd recommend the UK double instead, or the UK king if your room allows a little more width.

Is a small double Tempur Pro SmartCool big enough for a couple?
For occasional nights, yes. Across the 120cm width, the foam's low motion transfer helps two people share without disturbing each other, which makes it a sensible guest room choice. For every night, most couples find 4ft tight. If you'll share regularly, the UK double gives you 15cm more width to work with.
What room size do I need for a small double Tempur mattress?
We suggest allowing at least 2.4m x 2.8m. That leaves room to walk around the bed and open drawers or doors. In a loft conversion or box room, measure where the walls slope or the door swings, since the 120cm width is often what decides whether the layout works.
How big is the Tempur Pro SmartCool in a UK small double?
It measures 120 x 190cm, or 4ft x 6ft 3in, with the same 21cm depth as every size of this mattress. That makes it 30cm wider than the UK single, so a solo sleeper gains real spreading room, while staying narrower than a standard double for tighter rooms.
Will small double bedding fit this mattress?
Yes. This is the standard UK small double footprint at 120 x 190cm, so 4ft fitted sheets fit properly. A standard double duvet works well on top, with a little overhang on each side. Because 4ft is a common UK size, frames and bedding are straightforward to find.
Is the small double a good choice for a teenager?
Often, yes. A teenager who has outgrown a UK single gets 30cm more width to stretch out on, and the slow-response foam supports growing hips and shoulders evenly. Because it is 15cm narrower than the UK double, the room keeps more floor space, which usually matters in a teenager's bedroom.
