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.

- Room to spread out: The UK king is 15cm wider than the UK double, which means 75cm each for two people sharing rather than a nightly negotiation over the middle.
- Motion absorption gets space to do its job: The 8cm memory foam layer soaks up movement, and at this width your partner turning over happens further away from you in the first place.
- Length for taller sleepers: At 200cm long, the UK king suits anyone approaching 6ft whose feet currently meet the end of a 190cm double.
- Personal space on a moulding surface: Tempur's Adapt foam cradles each sleeper in their own spot, so with 75cm apiece you both get that contouring without overlapping impressions.
- Different schedules, fewer wake-ups: If one of you leaves for work hours before the other, the combination of width and the motion-absorbing layer makes an early exit far less disruptive.
- Fits a normal master bedroom: We suggest a room of at least 2.7m x 2.9m, comfortably achievable in most UK masters where a UK super king would feel like a squeeze.
This size suits you if...
You share the bed every night and the UK double has started to feel like a compromise, one of you is around 6ft or taller and wants the 200cm length, or your sleep schedules differ and you want the buffer of extra width on top of the foam's motion absorption. It also suits couples where a dog has become a regular third occupant.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m minimum, or you sleep alone and don't need 150cm of width. We'd recommend the UK double instead. If space is generous and you both sprawl, the UK super king adds 30cm of width.

Is the Tempur Ease UK king big enough for a couple?
Yes, comfortably for most. At 150cm wide it gives two people sharing 75cm each, and because Tempur's Adapt foam moulds around you where you lie, each sleeper effectively keeps their own zone. If you both like to starfish, the UK super king is 30cm wider, but for most couples the UK king is the sensible upgrade.
How much bigger is the UK king than the double for this mattress?
The UK king is 15cm wider than the UK double, and at 200cm it adds length too, which the 190cm double lacks. On a slow-response foam like this, that width shows up as fewer accidental nudges reaching the motion-absorbing layer, so the difference feels larger night to night than the numbers suggest.
What room size do I need for the Tempur Ease in a UK king?
We suggest a room of at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable. New build master bedrooms often look bigger on the plan than they are once wardrobes go in, so measure the free floor after furniture, allowing walking space along both sides of the 150 x 200cm mattress.
Is the UK king long enough for someone over 6ft?
At 200cm (6ft 6in), yes for most people. If you're around 6ft and currently on a 190cm double, the extra 10cm is often the change you notice first, more than the width. Anyone unusually tall should check clearance against the footboard of their bed frame, which can shorten usable length slightly.
Will my partner getting up early wake me on the UK king Tempur Ease?
Less than on a narrower size. The 8cm memory foam layer absorbs movement, and with 75cm each the person leaving is further from you when they shift. Reviews of dense memory foam generally support its motion isolation, so an early alarm on one side is unlikely to travel across a 150cm-wide surface.
