Layer Details
- TEMPUR Adapt material. A 3cm layer that adapts to your movements, warmth and body shape, which means the surface gradually moulds around you as you settle. It's what gives the mattress its personalised, cradling feel.
- Memory Foam. An 11cm layer of memory foam that absorbs movement as you turn in the night. In practice, that means less partner disturbance and a more settled feel if you share the bed.
- High density foam. An 11cm high density foam base that provides extra support and a sturdy feel. It's the durable foundation that helps the mattress keep its shape over the years.
Layer details from mattressonline.co.uk product page, September 2026.
- Room to sleep apart, together: At 15cm wider than a UK double, this size gives each of you your own settled patch of that body-moulding Adapt surface.
- Less disturbance on different schedules: The 11cm memory foam layer absorbs movement, which means an early alarm on one side is far less likely to wake the other.
- Extra length for taller sleepers: At 200cm long, the UK king adds 10cm over a double, welcome if either of you is approaching six foot.
- Space that survives a dog: If a pet claims the foot of the bed most nights, 75cm each leaves you room to stretch rather than negotiate.
- Substantial feel at full width: The 25cm depth and high density base keep the surface consistent right across 150cm, so the edges of your half feel as supportive as the middle.
This size suits you if...
You share the bed every night and a double has started to feel cramped, especially with the cradling foam holding you in place once you've settled. It also makes sense if one of you is tall and keeps finding feet off the end of a 190cm mattress, or if your mornings run on different clocks and you want the memory foam's motion absorption plus the width to keep early starts quiet.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest as a minimum, or you sleep alone. In either case the UK double would suit you better; solo sleepers get generous space without the footprint.

Is a UK king Tempur Ease big enough for a couple?
Comfortably, for most. At 150cm wide you get 75cm each, and the mattress's 11cm memory foam layer softens the movement you'd otherwise feel from a partner turning or getting up early. If you both sprawl, or a dog routinely joins you, the UK super king adds another 30cm of width.
Will the Tempur Ease king fit a tall sleeper?
Yes, and length is often the real reason to choose it. The UK king is 200cm long, 10cm more than a UK double, so anyone approaching six foot gets clearance rather than toes at the edge. The firmer high density base keeps support consistent along that full length too.
What room size do I need for the Tempur Ease in a 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 look on the plan, so measure with furniture in place before committing to the 150 x 200cm footprint.
How much wider is the king than the double in this mattress?
The UK king is 15cm wider than the UK double, and because the Tempur Adapt layer moulds to each body individually, that extra width translates into two distinct sleeping zones rather than one shared dip. It's also 30cm narrower than the UK super king, if space allows you to go bigger.
Where can I buy the Tempur Ease king at the best price?
Compare the retailers listed on this page. The prices shown here are updated as retailers change them, so it's worth checking back rather than assuming the brand's own site is cheapest. In imperial terms you're shopping for a 5ft x 6ft 6in mattress, the standard UK king.
