Layer Details
- 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.

- Room for two without dominating the bedroom: At 135cm wide, the UK double gives couples 67.5cm each for two people sharing, in a footprint most UK bedrooms take comfortably.
- Bedside tables on both sides usually still fit: In a room around our suggested 2.6m x 2.8m minimum, a UK double normally leaves space for a bedside table on each side, which a UK king often doesn't.
- Motion absorption matters most at this width: Sharing 135cm puts you close to your partner, so the slow-response TEMPUR® Advanced Material soaking up movement is genuinely useful rather than a nice-to-have.
- Easier to get upstairs than larger sizes: A 21cm deep foam mattress in a UK double is more forgiving on turning staircases and tight landings than a UK king or UK super king would be.
- Bedding is cheap and everywhere: Double sheets and a 200 x 200cm double duvet are stocked at every price point, handy if you're furnishing a whole home in one go.
- A sensible guest room choice: Firm support suits the widest range of visiting couples, and the UK double is the size guests expect to find.
This size suits you if...
You share the bed as a couple in a typical UK bedroom and want firm foam support without the bed swallowing the room, or you're kitting out a guest room where visiting couples need a proper shared size. It also suits a solo sleeper who wants space to spread out, perhaps with a dog or cat claiming a corner, and prefers a firm, slow-moulding feel.
Consider another size if...
You and your partner both like to sprawl, or one of you is broad-shouldered and 67.5cm each feels tight. We'd recommend the UK king instead: it's 15cm wider and 10cm longer than the UK double, and needs a room of at least 2.7m x 2.9m.

Is the Tempur Pro SmartCool Firm in a UK double big enough for two adults?
Yes, for most couples. A UK double is 135 x 190cm, giving 67.5cm each for two people sharing. That's the traditional shared size in the UK, and this mattress's slow-response foam helps by absorbing a restless partner's movement. Taller or broader couples may prefer the UK king, which is 15cm wider and 10cm longer.
What size room do I need for a UK double Tempur Pro SmartCool Firm?
We suggest a minimum of 2.6m x 2.8m, with around 3m x 3m being the comfortable norm. That allows walking space around the bed and, in most layouts, bedside tables on both sides. These are our own guidelines rather than Tempur's, so measure your room including door swing before ordering.
Will the UK double fit up a narrow staircase?
It's one of the easier sizes to move. At 135 x 190cm and 21cm deep, the UK double copes better with turning stairs in older terraces and tight new build landings than larger sizes. Foam has some give when manoeuvred carefully, though a dense Tempur mattress is heavy, so two people carrying it is sensible.
Should I get the double or the king in this mattress?
It depends on your room. The UK double suits bedrooms where a king would dominate, and fits where you want tables both sides in a modest space. If your room measures at least 2.7m x 2.9m and you'd value the extra 15cm of width and 10cm of length, the UK king is worth the step up.
