About the TEMPUR Pro Air SmartCool™ Medium 21cm Mattress
Last checked
Buyers looking at the TEMPUR Pro Air SmartCool™ Medium 21cm are really choosing a premium all-foam mattress rather than a sprung hybrid: its support comes from TEMPUR® Advanced Material and Pro Air foam, not from coils. The medium comfort grade is the key practical detail, because TEMPUR foam tends to feel slower and more body-hugging than standard polyurethane foam, spreading pressure gradually rather than giving the immediate push-back of pocket springs. At 21cm deep, it sits on the slimmer side for a premium memory-foam mattress; thicker memory-foam hybrids often add more cushioning depth or a spring unit for lift, while this build relies on denser foam behaviour and closer contouring. This is a relatively lean premium build. The SmartCool™ cover is the standout feature: it is removable, washable at 40 degrees, and carries the claim of cooling faster than other TEMPUR Pro covers, but that remains a surface-fabric claim rather than proof that the foam core will sleep cold. In construction terms, the value sits in pressure relief, motion absorption and the washable cover, not in layer complexity or bounce.
Dense viscoelastic foam is doing the comfort work here. That makes the mattress most persuasive for side sleepers, back sleepers and couples wanting less partner disturbance, and feedback repeatedly links it with fewer back aches, easier all-night sleep and better comfort for sore joints, including arthritis. For average-weight sleepers who want contouring without the very deep sink of taller TEMPUR models, the 21cm medium version makes sense, although heavier side sleepers may want more shoulder depth than this slimmer profile offers. Heat is the main caveat. A recurring complaint is that the SmartCool™ cover does not overcome the warm, enveloping character of memory foam, with the comfort and support praised even while the mattress still feels too hot for temperature-sensitive sleep. Adjustment is another snag: the slow-moving foam can take time to feel familiar, and sitting up or shifting position is harder than on a springier mattress. If cushioned pressure relief and low partner disturbance matter most, this works. If reliable cooling or a firmer sit-up platform is the priority, a cooler hybrid or firmer pocket-sprung tier makes more sense.

Not as cool as I expected it to be, but so comfortable
I now look forward to going to bed each night as this mattress is so comfortable. I wake up feeling refreshed without back aches and pains
I had an excellent experience with Dreams. The shop assistants were helpful without being pushy and explained about the mattresses available. The mattress we bought was easy and comfortable. The mattresses arrived as planned and the drivers were helpful, pleasant and professional. The entire process was excellent.
I have found this mattress an absolute pleasure to sleep on! After experiencing it's initial firmness. It now supports the contours of my body leading to a good night's sleep!
The best mattress I've ever had, so comfortable, supportive yet soft. Well worth the money.
Massively 0verpriced. It would be expensive at half the price! My choice , but I expected better.
The best mattress I had, very happy with my purchase
Best mattress Ive ever had, cradles every inch of your back and gets rid of our backaches. A dream!
Dreams sleep test is a must. We wanted a Tempur mattress, but without taking the sleep test would have chosen the wrong firmness. The test made sure we were fitted correctly and I have not ever slept better.
Amazing mattress makes such a difference to a bad back. Can finally sleep all night.
Best mattress ever had really bad shoulders suffered with pain every night . New tempur mattress solved the problem your body just moulds to it so comfortable. Was recommended by a friend . Did not believe it until I got one myself well impressed.
After suffering with back problems for years this has been a game changer!
Brilliant buy. Dreams got it just right for us. Thank you.
Mattress is light and we have not slept more comfortably since its arrival
Sleeping like a baby on the most comfortable mattress ever. Worth every penny and I would buy again (in fact we did).
Best Products bought from Dream Mattress and Frame
I tested out the soft, medium and firm Tempur mattress in Dreams store in New Cross. They are expensive, but come with a guarantee and a no quibble return within180 days which sold me on the brand.
At first I wasnt sure ..thought it was hard and couldnt move about very easily. But after sleeping on it I changed my mind, it feels like the bed hugs you and I got the best nights sleep in years!
Amazing mattress. The best nights sleep Ive ever had.
Mattress has been very comfortable so far , very pleased with quality and the pillows that came with it are also good.
