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.

Key benefits
- 75cm each for two people sharing: That's your own clear stretch of mattress, so one of you shifting position doesn't force the other to the edge.
- Foam that keeps movement local: TEMPUR® Advanced Material absorbs motion rather than transmitting it, and on a UK king width your partner's restlessness barely reaches your side.
- 15cm wider than a UK double: It sounds modest on paper, but split between two sleepers it's the difference between negotiating space and simply having it.
- 200cm of length for taller sleepers: If one of you is approaching 6ft, the extra length means feet stay on the mattress rather than hanging past the end.
- Fits a normal master bedroom: We suggest a room of at least 2.7m x 2.9m, which most UK master bedrooms can manage without giving up wardrobe space.
This size suits you if...
You share the bed every night and a double has started to feel cramped, especially with a mattress you sink into rather than roll across. You or your partner keeps odd hours and you want the early alarm, or the late return to bed, to go unnoticed. Or one of you is tall and it's length, more than width, driving the upgrade.
Consider another size if...
Your bedroom is under our suggested 2.7m x 2.9m minimum, or you mostly sleep alone. We'd recommend the UK double instead, which keeps the same slow-moulding feel in a footprint that leaves room to move around the bed.

FAQ's
Is the Tempur Pro SmartCool in a UK king good for couples?
Yes, and it's arguably the size where this mattress makes most sense for two. You get 75cm each for two people sharing, and the slow-response foam soaks up movement, so a partner turning over or getting up early is far less likely to wake you than on a sprung bed.
Will a UK king Tempur Pro SmartCool fit my bedroom?
The mattress measures 150 x 200cm, or 5ft x 6ft 6in. We suggest a room of at least 2.7m x 2.9m so you can open drawers and walk round both sides, with 3.2m x 3.2m feeling comfortable. Newer builds can be tighter than they look once wardrobes go in, so measure with furniture in place.
Is the UK king long enough for someone over 6ft?
At 200cm it's 10cm longer than a UK double, which is often the real reason taller sleepers upgrade. The foam also moulds around you rather than pushing back, so you're less likely to drift down the bed overnight. Anyone well over 6ft may still want to lie on one before committing.
Is it worth going from a double to a king for this mattress?
If you share the bed, usually yes. The UK king is 15cm wider than the UK double, and because this foam holds you in place rather than letting you roll about, having a defined stretch of your own matters more than it would on a bouncier surface. Solo sleepers gain less from the extra width.
Should I choose the UK king or the UK super king?
The UK king is 30cm narrower than the UK super king, so if your room comfortably exceeds our 2.7m x 2.9m suggestion and you want maximum separation, sizing up is tempting. For most couples the UK king is the better balance: generous space each without dominating the room. Compare the retailers listed on this page for both.
