Cover
A QuickRefresh™ cover with SmartCool™ technology, designed to help the surface feel cooler when you get in. That matters with foam mattresses, which can otherwise run a little warm.
Core
TEMPUR® Advanced Material, a slow-response foam that moulds to your body under heat and pressure. You sink in gradually rather than bouncing, which spreads your weight and eases pressure points.

Key benefits
- Real space for one: At 120cm wide it is 30cm wider than a UK single, so a solo sleeper who likes to sprawl gets room to do it.
- Fits where a double will not: It's 15cm narrower than a UK double, which can be the difference between the door clearing the bed frame and it not.
- Firm support in a small footprint: The extra firm feel keeps you supported near the edge, useful when a compact room means you sleep closer to it.
- Quiet for occasional sharing: TEMPUR® Advanced Material absorbs movement rather than transferring it, so guests sharing for a weekend won't feel every turn.
- Standard 4ft bedding: Small double is a standard UK size, so frames and fitted sheets are easy to find, with a normal double duvet on top.
This size suits you if...
You sleep alone and have outgrown a single but your room can't take a full double, you're furnishing a box room, loft conversion or studio where every centimetre of floor matters, or you're setting up a guest room that hosts a couple a few weekends a year. Allow at least 2.4m x 2.8m of floor space so you can still move around the bed.
Consider another size if...
You share the bed every night, as 120cm feels tight for two adults over the long run. If your room can take it, we'd recommend the UK double instead, which is 15cm wider.

FAQ's
Is the small double Tempur Pro SmartCool Firm big enough for a couple?
For the odd night, yes. The foam absorbs movement well, so occasional guests won't disturb each other much. As a nightly bed for two adults, 120cm is a squeeze, and the UK double would be the better long-term choice. As a guest room bed used a few weekends a year, the small double is a sensible pick.
What room size do I need for a small double mattress?
We suggest allowing at least 2.4m x 2.8m. That leaves enough space to open the door, walk down one side and get dressed without climbing over the bed. In a loft conversion or box room, measure where the ceiling slopes too, since a 4ft bed often fits where a full double leaves nowhere to stand.
How much wider is a small double than a single?
The UK small double is 30cm wider than the UK single. That extra width is the point of this size: it turns a bed you fit on into one you can stretch out on, without stepping up to the footprint of a UK double. For a teenager or adult moving on from a single, it's a noticeable upgrade.
Is the Tempur Pro SmartCool Firm small double a good choice for one person?
It suits a solo adult well. You get real room to spread out, and the firm, slow-response foam holds you in place rather than letting you roll toward the middle. Lightweight side sleepers may find the extra firm feel a little hard on shoulders and hips, and it softens slightly only after a few weeks of use.
