QuickRefresh™ cover
A cover with SmartCool™ technology that unzips all the way round, which means you can remove it without wrestling the mattress. It washes at 60°C, hot enough to deal with dust mites and allergens.
TEMPUR® Advanced Material
A generous layer of Tempur's slow-response foam, which the brand describes as its best pressure relief yet. It moulds to your shape as it warms, easing weight away from hips and shoulders.

Key benefits
- Real personal space for two: At 75cm each for two people sharing, you can both sink into the foam without settling into each other's dip.
- Less partner disturbance: Slow-response TEMPUR Advanced Material absorbs movement, so an early riser slipping out at 6am is far less likely to wake the other side.
- Length for taller sleepers: The UK king is 10cm longer than the UK double at 200cm, which keeps feet on the mattress if either of you is nearing 6ft.
- Pressure relief across the full width: The soft foam cradles hips and shoulders wherever you settle, useful when pregnancy or recovery has you shifting position through the night.
- A washable cover at this scale: The QuickRefresh cover unzips all the way round, which means you can strip a king-sized mattress for a 60°C wash without a wrestling match.
This size suits you if...
You share the bed every night and a double has started to feel cramped, especially with a soft, contouring mattress where you sink in rather than lie on top. It also fits if one of you gets up hours before the other, since the extra width and slow-moving foam keep disturbance low, or if either partner is tall enough to appreciate the 200cm length.
Consider another size if...
Your bedroom can't offer the 2.7m x 2.9m we suggest as a minimum for a UK king. In that case we'd recommend the UK double instead: you keep the same soft Tempur feel in a footprint that leaves room to move around the bed.

FAQ's
Is the Tempur Pro Plus SmartCool in a UK king good for couples?
Yes, and arguably more so than firmer mattresses in this size. Soft, slow-response foam means you sink in, so the 75cm each for two people sharing stops you feeling crowded into one another's space. The foam also absorbs movement well, so a restless or early-rising partner disturbs you less than on a springier bed.
Is a UK king Tempur long enough for someone over 6ft?
At 200cm, the UK king is 10cm longer than the UK double, and that difference is often the whole point of the upgrade for taller sleepers. On a soft foam mattress your heels would otherwise hang past the edge and lose support, so the extra length is felt rather than theoretical.
What room size do I need for the Tempur Pro Plus SmartCool UK king?
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. New build master bedrooms can be tighter than they first appear, so measure with your existing furniture in place before committing to the 150 x 200cm footprint.
Should I pick the UK king or size down to the UK double?
If you share nightly, the UK king is 15cm wider than the UK double, and on a soft mattress that gap is felt every night because you settle into the foam rather than lying on top. Size down only if the room genuinely can't take it; the mattress itself is identical in feel and construction.
Where can I find the best price on this mattress in a UK king?
Tempur prices vary between retailers, and larger sizes like the UK king are where the differences tend to widen. The prices shown on this page are updated as retailers change them, so compare the retailers listed here rather than assuming the brand's own site is cheapest.
