Layer Details
- Cover. A QuickRefresh cover with SmartCool technology. It sits at the surface, so it's the first thing you feel when you lie down.
- Core. TEMPUR Advanced Material forms the core of the mattress. This slow-response foam moulds to your shape and eases pressure at the heavy points of your body.

- A shared size that fits real rooms: At 135cm wide, the UK double sits comfortably in bedrooms where a UK king would leave you squeezing past furniture.
- Firm support in a couples' footprint: The dense TEMPUR Advanced Material holds a solid, contouring surface across the full 135cm, so neither of you ends up rolling into a dip.
- Slow foam suits close sharing: Slow-response foam absorbs movement rather than bouncing it, which matters more at 67.5cm each than it would on a wider mattress.
- Standard bedding, no hunting: A UK double takes the most widely stocked sheets and duvets in Britain, useful when you're kitting out a whole home in one go.
- Room for tables both sides: In a room of around 3m x 3m, this size usually leaves space for bedside tables on both sides, something a UK king often sacrifices.
This size suits you if...
You share the bed most nights and your room comfortably takes a 135 x 190cm mattress but would feel dominated by anything wider, or you sleep alone and want space to stretch out on a firm, moulding surface. It also fits a guest room that hosts visiting couples, where the firm feel is a safe bet for back and front sleepers.
Consider another size if...
You and your partner both like space and your room measures well beyond our suggested 2.6m x 2.8m minimum. The UK king is 15cm wider and gives each of you a noticeably easier night on this firm foam.

Is a UK double Tempur Pro Plus SmartCool Firm big enough for two adults?
It works, with a caveat. At 135 x 190cm you get 67.5cm each, which most couples find enough. The slow-response TEMPUR Advanced Material helps here, since one person turning over doesn't jolt the other. Larger sleepers, or couples who spread out, may prefer the UK king at 150cm wide.
What room size do I need for the Tempur Pro Plus SmartCool Firm double?
We suggest a room of at least 2.6m x 2.8m for a UK double, with around 3m x 3m being the comfortable norm. That larger figure leaves space for a wardrobe, drawers and bedside tables on both sides, the typical layout of a first flat or second bedroom.
How much narrower is the UK double than the UK king in this mattress?
The UK double is 15cm narrower than the UK king. It is also 15cm wider than the UK small double, so it sits in the middle of the shared sizes. On a firm foam like this, where you sink in place rather than sprawl, that middle width suits most couples in average sized rooms.
Will a Tempur double get up the stairs in an older house?
Tempur's foam is dense and this mattress is 25cm deep, so a 135cm wide double takes some manoeuvring on turning staircases in older terraces or tight new build landings. It flexes less readily than a cheap foam mattress, so measure your tightest corner before ordering and check the retailer's access guidance.
