Key benefits
- 75cm each for two sharing: Each of you gets 75cm of width, so a partner who reads late or rises hours earlier has room to move without crowding you.
- Extra length for taller sleepers: At 200cm, the UK king is 10cm longer than a UK double, a genuine relief for anyone approaching six foot on a firm surface that discourages diagonal sprawling.
- Firm support across the full width: The extra-firm feel is consistent edge to edge, so the sleeper nearest the side isn't perched on a softer margin.
- Pressure relief that scales with space: The slow-response foam spreads weight at your hips and shoulders, which means more width lets each of you find a settled position and stay in it.
- Room for the dog, within reason: If a pet joins you most nights, 150cm absorbs that better than a UK double, though a very firm surface does make every occupant's position more deliberate.
This size suits you if...
You share the bed every night and a UK double has started to feel cramped, you and your partner keep different hours and want space to come and go with less disturbance, or one of you is tall enough that the 200cm length is the real draw. It suits couples with a bedroom of at least 2.7m x 2.9m who want firm support without going up to super king proportions.
Consider another size if...
Your bedroom is smaller than the 2.7m x 2.9m we suggest for a king, or you sleep alone and won't use the width. In either case we'd recommend the UK double instead, which keeps the same firm Tempur feel in a smaller footprint.

FAQ's
Is the Tempur Pro Plus SmartCool Firm available in a UK king?
Yes. The UK king measures 150 x 200cm, or 5ft x 6ft 6in, and is 25cm deep. It's one of twelve sizes this mattress comes in, and you can compare the retailers listed on this page, with prices updated as retailers change them.
How much space does the UK king give each person?
75cm each for two people sharing. That's a meaningful step up from a UK double, which is 15cm narrower overall, and it matters on a firm mattress like this one because you tend to settle into a spot rather than drift across the surface.
Will a UK king Tempur Pro Plus SmartCool fit my bedroom?
We suggest a room of at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable once wardrobes and bedside tables are in. New build master bedrooms can be tighter than they first appear, so measure with furniture positions in mind before committing to the 150 x 200cm footprint.
Is the UK king long enough for a tall sleeper?
At 200cm, the UK king gives you 10cm more length than a UK double. For anyone approaching six foot, that stops feet hanging off the end, which is worth having on a firm foam surface where you're less inclined to curl up or lie diagonally.
Is this mattress a good choice for couples in a UK king?
Broadly yes, if you both like a solid feel. The slow-response foam moulds to each sleeper individually and the 75cm each gives you room to do so. Lightweight side sleepers may find it a little too firm at the shoulder, so agree on firmness before agreeing on size.
