About the TEMPUR Pro Air SmartCool™ Soft 21cm Mattress
Last checked
The 21cm build is a premium all-foam TEMPUR mattress, using the brand’s pressure-relieving viscoelastic material under a removable SmartCool™ cover that can be machine washed at 40 degrees. Its comfort grade is soft, so the promise is body-hugging sink rather than lifted, springy resistance, with the foam spreading load across hips and shoulders and taking the edge off partner movement. The 18% cooling claim is cover-led. A 21cm depth is restrained for the premium memory-foam tier; deeper all-foam mattresses often use more transition foam to slow down bottoming-out, while memory-foam hybrids add springs for lift, so this is a lower-profile, easier-to-dress design rather than a maximal support stack. That restraint is not automatically a flaw: one owner specifically liked the lower height and easier handling after moving from a deeper, firmer sprung mattress. But the practical reality is that the SmartCool surface does not turn TEMPUR foam into a breathable pocket-sprung unit; it gives a faster cool-touch surface at the top, while the core remains a close-conforming foam that will feel slower-moving and more enveloping than traditional sprung construction.
People moving away from hard sprung beds, especially side sleepers with sore hips, lighter frames or arthritis, are the clearest match here because the foam cradle is exactly the behaviour praised most often. Sleep quality improves, with pain relief, fewer overheated nights and a refreshed morning feel coming through repeatedly, and that matches the specification: TEMPUR material reduces pressure points while the SmartCool cover takes the first hit of body heat. The soft label over-promises for some. A recurring complaint is that the mattress feels firmer than expected, so anyone expecting a squashy pillow-top or very plush hotel feel may find the initial surface too resistant, even though it may relax with use. Temperature feedback is split in a useful way: hot sleepers describe the surface as cooler than their previous mattresses, but a colder sleeper found the touch too cold in winter and was frustrated by care guidance around heated bedding and hot-water bottles. For couples, the all-foam construction is sensible where one person turns often, because motion absorption is a genuine strength of this material; the weaker fit is for sleepers who rely on spring bounce to change position easily. Best for light-to-average side sleepers wanting pressure relief and a cooler-feeling foam surface. Less good for cold sleepers or anyone expecting ultra-soft sink, who would do better with a plusher pillow-top or a firmer-tested pocket-sprung tier.

I love my new bed it so so comfortable and the anti snore really works it wonderful
I have definitely been sleeping better since I replaced my firm sprung mattress with my new soft Tempur mattress. It is also lighter weight so easier to make the bed, and less deep so I don't have to jump to get on to it! It will be interesting to see whether it really is cool in hot weather, but I will have to wait a few months to find out.
Absolutely brilliant. Don't want any other mattress ever again.
Fantastic mattress. Comfortable. Has reduced my back pain immensely
I find the Tempur pro air smart cool mattress very comfortable, I certainly get a better night sleep and feel refreshed in the mornings. The mattress does keep me cool as well.
Such a comfy mattress! Wish Id got one a long time ago!
Brilliant so comfortable for my health and mobility issues
After the initial smell had gone I love it sleeping well
I cannot speak highly enough of this mattress, it really is so comfortable. I used to wake up feeling like I had been knocked about, I had so many aches and pains. Now I enjoy a good nights sleep and wake up feeling refreshed and pain free. Thank you Tempur!
Great service but still getting used to a new mattress!
Very comfortable although slightly firmer than we expected. Hopefully it will soften more over time.
This mattress will feel like you are sleeping on a supportive cloud. Great for those who want soft comfort but also the support as this mattress contours your body and supports you where you need it most. The exclusive Air SmartCool™ cover dreams offer helps draw away excess moisture so perfect for hot sleepers.
This is a really comfortable mattress. My son loves it.
Myself and partner both love this mattress. Its so comfy and alleviates all my back aches from the day. It is quite cool to touch and I do feel the cold quite a bit however I have a fleece sheet covering it and the Tempur duvet and its perfect. I have also found I am more refreshed in the morning after a perfect nights sleep.
OMG I have a lot of arthritis and have spent most of the last ten years struggling to sleep for the pain. Now I'm getting good night's sleep,it's like a miracle, I was hopeful but it's gone way past my hopes. It is an amazing technology, It dips around the body and rises back up as I move. I can get onto a bony hip and it's cradled in softness that manages to still be supportive. This mattress was worth every penny spent on it. If it's super comfy with arthritis then a good sleep is guaranteed to all. I love it.
Bought this to replace a 17 year old too firm mattress which I could only continue using with toppers! (Even then my bony frame was getting sore when it met the mattress.) As I am elderly with the usual arthritis and so on, and only weigh eight stone, I decided to go on the test bed in store, and discovered I should be on a softer mattress. Tried the three recommendations and went for this one. Not cheap, but you get what you pay for. Worth waiting for. Delivered as arranged and I removed plastic wrap after an hour. Then I let it breathe for two days to allow slight chemical smell to dissipate. During those nights I slept on my sofabed. Then on the third night I made up my new mattress with the recommended protector and my bedding. It was bliss and have slept so well ever since. Very very comfy and I am not waking up really hot like I used to. ( I am a hot sleeper/side sleeper but also feel the cold in hands and feet). This mattress, and pillows bought at same store, are just right for me. And will also probably protect me from developing pressure sores as I age.
In love with my Tempur mattress. This one wasn't as thick as others but works great on my Murphy bed - not too heavy to lift. This version isn't quite as comfortable as my parents' thicker Tempur mattress but still helps with my aches, pains, and insomnia (fibromyalgia symptoms)
So far so good The Dreams team were really helpful and am very happy with my purchase
