Layer Details
- TEMPUR Adapt Memory Foam. A 3cm top layer with ultra sensitive cells that shape to your body and respond to your weight and temperature, which means a gradual, cradling sink rather than an instant one. This is the layer that gives Tempur its distinctive slow-response feel.
- Memory Foam. An 8cm layer that absorbs motion as you move during the night. In practice, that means less partner disturbance when one of you turns over or gets up.
- High Density Foam. A 9cm base layer that creates a solid, sturdy foundation for the softer foams above. It's what keeps the mattress feeling supportive edge to edge rather than saggy.

- A shared size that fits the room: At 135 x 190cm, the UK double leaves space for furniture in a typical bedroom, and we suggest a room of at least 2.6m x 2.8m.
- 67.5cm each for two people sharing: That's the width each of you gets in a UK double, and the Adapt foam moulds to each sleeper individually within it.
- Motion absorption matters more at this width: With 67.5cm each for two people sharing, the 8cm motion-absorbing layer means a partner turning over close beside you is less likely to wake you.
- Room for bedside tables on both sides: The UK double is 15cm narrower than the UK king, which often makes the difference between fitting two bedside tables or one.
- Easy to move in and dress: A 20cm deep double is lighter to steer up a turning terrace staircase than a king, and double bedding is stocked everywhere at every price.
This size suits you if...
You share the bed most nights and your room sits around the typical UK bedroom size, where a UK king would leave you squeezing past furniture. Or you sleep alone and want proper space to spread out, perhaps with a dog or cat claiming a corner. It also suits a guest room that needs to host visiting couples without dominating the space.
Consider another size if...
You and your partner both toss and turn, or one of you is broad-shouldered, and 67.5cm each for two people sharing feels tight. If your room allows it, we'd recommend the UK king instead for the extra width.

Is the Tempur Ease double big enough for two adults?
For most couples, yes. The UK double gives 67.5cm each for two people sharing, and the Ease's 8cm motion-absorbing layer softens the disturbance of a partner moving that close by. Larger-framed couples, or restless sleepers, may find the width limiting; the memory foam holds you in place rather than letting you roll about, which some find helps.
What room size do I need for the Tempur Ease in a UK double?
We suggest a room of at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. The double's 135 x 190cm footprint usually leaves enough clearance for a wardrobe, a chest of drawers and bedside tables on both sides, which is where a UK king often starts forcing compromises.
Should I get the Tempur Ease in a double or a king?
It comes down to your room. The UK double is 15cm narrower than the UK king, and in a modest bedroom that gap decides whether doors open freely and both bedside tables fit. If your room comfortably exceeds 3m x 3m and you share every night, the UK king gives welcome extra width; otherwise the UK double is the safer call.
Will a double Tempur Ease fit up narrow stairs?
Memory foam mattresses have some flex, and at 20cm deep and 135cm wide the double is one of the more manageable sizes to manoeuvre through a turning staircase in an older terrace or a tight new build landing. Measure your narrowest point first, and check the retailer's delivery guidance, since handling policies vary between the retailers listed on this page.
What bedding fits the Tempur Ease double?
Standard UK double bedding: 135 x 190cm fitted sheets and a 200 x 200cm double duvet. Check the fitted sheet's stated depth covers the mattress's 20cm before buying, though most standard sheets manage this easily. Double bedding is the most widely stocked size in the UK, so you'll find options at every price.
