Assessed from the specification published by Mattress Online, captured September 2026, and from regular price comparison across our UK retail partners.
The main draw is the material itself. Tempur Adapt foam shapes to your body and adjusts to your temperature, which means pressure is spread more evenly across hips and shoulders, something side and back sleepers with aches tend to feel quickly. The 8cm motion-absorbing layer underneath makes it a sensible pick for couples. At 20cm deep it's shallower than some rivals, yes, but the high density foam base keeps it feeling solid rather than flimsy. It conforms to BS7177: 2008 for home fire safety and is certified by The Space Foundation. Sizes run from UK Small Single to Super King, plus an EU Single, and it's stocked by 5 retailers, so you can shop around.
Key Features & what's inside
- 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.

Who's it NOT for?
Hot sleepers should think carefully: owner reviews mention warmth retention, a known trait of dense memory foam. Anyone who prefers a springy, responsive surface may find the slow-sinking feel a little enveloping. And lightweight sleepers wanting a plush, soft mattress may find the medium to firm feel firmer than expected.
Tempur Ease 20cm Mattress
How firm is the Tempur Ease mattress?
It's described as medium to firm. The Tempur Adapt top layer softens with your body heat, so it feels more cradling once you've settled in, but the overall support is on the firmer side. Lightweight side sleepers may find it slightly firm at first.
Does the Tempur Ease come with a trial and guarantee?
Terms depend on where you buy. MattressOnline lists a 100-night trial and a 10-year guarantee, with a separate 2-year guarantee on the cover, but these are that retailer's own offers rather than Tempur's. Check the terms with whichever retailer you choose.
How deep is the Tempur Ease mattress?
It's 20cm deep, made up of a 3cm Tempur Adapt layer, an 8cm memory foam layer and a 9cm high density foam base. That's slimmer than many premium mattresses, though the dense construction means it doesn't feel insubstantial.
Is the Tempur Ease good for couples?
It's a strong option. The 8cm memory foam layer is designed to absorb motion, which means you're less likely to feel a partner moving or getting up in the night. It's available in UK Double, King and Super King sizes.
Does the Tempur Ease sleep hot?
Some owner reviews mention warmth retention, which is common with dense memory foam. The Adapt layer does respond to body temperature as part of how it moulds to you. If you're a very hot sleeper, a hybrid or sprung mattress may suit you better.
