The TEMPUR Ease 20 Mattress is the cheapest way into TEMPUR's material, and the catch is how little of it you get: a 3cm layer on top of ordinary memory foam and a high density base, 20cm in all. Buy it if you've slept on TEMPUR before, loved the slow sink, sleep cool and want the name for less. Hot sleepers, heavier sleepers and anyone who turns a lot in the night should skip it. To my mind TEMPUR is an overpriced legacy brand, and on this model you're mostly paying for the badge.
Three centimetres of the famous stuff
The layers are listed plainly. TEMPUR Adapt sits at the top in a 3cm layer, viscoelastic and open-celled, which TEMPUR says lets it breathe. Under it are 8cm of standard memory foam and then 9cm of high density foam for support, with no springs anywhere. So most of what you sink into is memory foam you'll find in plenty of cheaper mattresses, with a thin skin of TEMPUR on top. It does what memory foam does well. It moulds to you, and a partner turning over stays on their own side.
The cover unzips for the wash and carries its own, shorter guarantee, separate from the mattress. It's single-sided, so you rotate it top to toe with the seasons.
A new name on the same kind of bed
Mattress Online used to sell The ONE by TEMPUR Medium on this listing, and the Ease 20 has taken its place on TEMPUR's newer entry line. On paper it's the same sort of bed, 20cm of foam with TEMPUR material on top. The old listing's claims of a firm TEMPUR layer and a Danish factory aren't repeated for the Ease, so don't assume either. Some of the older reviews are for the earlier model.
Happy owners, and the heat question
The owners are a happy bunch, which deserves credit, though many wrote about the earlier model. The newer ones say it's comfortable, and one found their back and hips eased. Another calls it "a little warm" and reckons that'll be perfect in winter. I laughed, because I'm no judge of seasons myself: I drink iced coffee in January. Memory foam holds warmth whatever the open cells promise, so if you overheat, believe that owner over the brochure.
Heavy or restless sleepers should pass
Give it a miss if you weigh more than about eighteen stone, because 20cm of foam with a 9cm base is light support for that weight. Avoid it if you change position a lot, since deep memory foam turns to quicksand the moment you try to roll over. Skip it if you need a small double, which it isn't sold in. One owner says it suits their adjustable bed, and an all-foam mattress bends with a base more easily than a sprung one, so that's a niche where it earns its keep.
What to buy instead
I'd keep my money. TEMPUR's PRO SmartCool line is where the brand puts its best foam, and the step up costs plenty. For the money the Ease 20 asks, buy a memory foam hybrid on pocket springs: you get the hug on top, springs that breathe underneath and more support for heavier bodies. If it must be TEMPUR, buy it in a sale and weigh that price against a good hybrid, never against the "was".
