The main reason to choose the Ease is that adaptive top layer. It softens with your body heat, which means pressure points at your shoulders and hips get a gentle cradle while the medium to firm base keeps your spine supported. The thick memory foam layer beneath absorbs movement as you turn, so if you share a bed with a restless partner you should feel less of their tossing. At 25cm deep with a high density foam base, it also feels reassuringly substantial. Yes, the price is higher than many foam mattresses, but the 10-year guarantee and Tempur's durability record go some way to justifying it.
Key Features & what's inside
- 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.

Who's it NOT for?
If you prefer a springy, responsive surface, the slow-moving foam feel here may frustrate you. Hot sleepers should also think carefully, as all-foam designs tend to hold more warmth than sprung ones. And with a medium to firm feel, very lightweight side sleepers may find it slightly too firm for full pressure relief.
Tempur Ease 25cm Mattress
How firm is the Tempur Ease mattress?
It's described as medium to firm. The adaptive top layer softens with your body heat to cradle pressure points, while the high density base keeps things supportive, so it suits most back and front sleepers, although lightweight side sleepers may find it a little firm.
Does the Tempur Ease come with a trial period?
Mattress Online lists a 100-night trial with this mattress, but that's the retailer's own offer rather than a Tempur guarantee, so check the terms wherever you buy. The 10-year guarantee, by contrast, appears to be a manufacturer guarantee.
How long is the guarantee on the Tempur Ease?
It comes with a 10-year guarantee, which gives you long-term reassurance on a mattress at this price point.
How much does the Tempur Ease 25cm mattress cost?
Prices range from £637 to £1,096 depending on size, starting at £637 for the smallest option. That's a premium price for a foam mattress, but the adaptive Tempur material and 10-year guarantee help explain it.
What sizes does the Tempur Ease come in?
Six sizes are available: UK Small Single, UK Long Single, UK Double, UK King, UK Super King and EU Single. Note there's no standard UK Single in the range, so check the Small Single or Long Single dimensions carefully if that's what you need.
