Cover
A QuickRefresh cover with SmartCool technology, designed to help the surface feel cooler to the touch. It sits over the foam as your first line of defence against overheating.
Filling
TEMPUR Advanced Material, a slow-response foam that softens with body heat and moulds closely to you. You'll feel a gradual sink-in rather than an instant bounce.

Key benefits
- Proper space for two: At 150cm across, the UK king is 15cm wider than the UK Double, which means room to change position without negotiating for territory.
- Quiet nights on different schedules: Slow-response foam absorbs movement rather than bouncing it across the bed, so an early alarm on one side is far less likely to wake the other.
- Length for taller sleepers: The 200cm length gives anyone approaching six foot room to stretch out without their feet meeting the end of the bed.
- Cooling where two bodies share: Two sleepers generate more heat than one, and the SmartCool cover is aimed at keeping the surface cooler across the full 150cm width.
- A manageable upgrade: The UK king is 30cm narrower than the UK Super King, so most master bedrooms can take it once wardrobes and bedside tables are in.
This size suits you if...
You share the bed every night and a double has started to feel cramped, especially if one of you gets up hours before the other and you want that movement absorbed rather than felt. It also fits if one partner is tall and it's length, more than width, that's been the problem, or if the dog has quietly become a permanent third sleeper.
Consider another size if...
Your bedroom is under our suggested 2.7m x 2.9m minimum, or you sleep alone and would rather spend less on width you won't use. In either case we'd recommend the UK double instead; sprawling couples with a bigger room should consider the UK super king.

FAQ's
Is the Tempur Pro Plus SmartCool UK king big enough for a couple?
Yes, comfortably for most. At 150 x 200cm it gives 75cm each for two people sharing, noticeably more than a double, and the slow-response foam means you feel your own space rather than your partner's movement. Couples who sprawl, or who share with children or a large dog, may still prefer the UK super king.
Will the UK king reduce partner disturbance on this mattress?
This is where the size and the material work together. TEMPUR Advanced Material absorbs motion instead of springing it back, and the 150cm width puts more distance between you. If one of you leaves for work hours before the other, the combination makes an early exit far easier to sleep through.
Is the Tempur Pro Plus SmartCool UK king long enough for tall sleepers?
At 200cm, the UK king is 10cm longer than a UK double, which is often the real reason taller couples upgrade. Anyone approaching six foot gets clearance without their feet hanging off the end, and the foam moulds along the full length of the body rather than at pressure points alone.
What room size does this UK king mattress need?
We suggest at least 2.7m x 2.9m, with around 3.2m x 3.2m feeling comfortable once wardrobes and bedside tables are in place. New build master bedrooms can be tighter than they look on a floor plan, so measure with the furniture in position, and remember the mattress itself is 150 x 200cm.
