About the TEMPUR EASE® 25cm SmartCool™ Mattress
Last checked
Average-weight sleepers wanting the TEMPUR feel are the clearest audience here. The TEMPUR EASE® 25cm SmartCool™ Mattress is a 25cm all-foam model, built around TEMPUR Adapt® material over dual base layers, with a medium-firm feel, 4 out of 5, and a removable SmartCool™ cover washable at 30°C. This is a proper full-depth foam build. The honest reading is that the premium is being spent on pressure-relieving proprietary foam and cover technology, not on pocket springs, zoned support or natural upholstery; compared with memory-foam hybrids, the support will feel slower, less bouncy and more body-hugging under load. The NASA-origin story is brand heritage rather than a separate comfort layer, so the practical feature is still the contouring foam: it softens with warmth, spreads pressure and holds the sleeper in a more settled position than open-coil or pocket-sprung mattresses. SmartCool™ is useful, but it should be read as cool-to-touch fabric rather than active climate control, especially because dense memory foam naturally has more hug and less airflow than a sprung build with breathable fillings.
TEMPUR Adapt foam is slow-response, body-contouring material, not a spring unit. That makes most sense for back sleepers and side sleepers of average build who want cushioning without a plush, sinking-top feel, particularly where a steadier surface matters more than bounce. Praise clusters around comfort, firmer support and noticeably better sleep, with some buyers describing an initial adjustment period after moving from a sprung mattress before the feel becomes familiar. The comfort mismatch is still real. The lowest scores cut in opposite directions: one complaint finds it hard and unforgiving around hips, knees and back, while another describes softening into a hollow, so the medium-firm label does not land the same way across body shapes and expectations. Hourglass side sleepers who need deeper shoulder and hip sinkage are the obvious risk group, while back sleepers wanting a flatter, steadier platform are better aligned with the build. Sheet slippage also appears as a practical frustration in a detailed complaint, and the smooth cover may be less grippy than traditional damask or quilted ticking. This suits average-weight back sleepers and side sleepers who like a slow, medium-firm memory-foam hug; those prioritising softer hip sinkage, springy response or stronger airflow should look instead at softer all-foam models or memory-foam hybrids.

Really comfortable and supportive with a nice cool feel, though the delivery took longer than expected.
Absolutely grand experience with this product. The cool-touch cover works like a charm and the comfort is unbeatable, very satisfied.
Extremely comfortable mattress, weve just had a new born baby and this helps you maximise you comfort in the sleepless nights
Salesman great and dealt with efficiently and promptly
A bit strange at first, but now it is lovely, best sleep ever. Service from Dreams was first class.
Best purchase of my life..no more back pain.quality sleep.isnt technology wonderful
Amazing mattress, had a few weeks now and is so comfortable
Fabulous customer service from the sales lady who dealt with my order .Nothing was of any trouble though I would say I was a bit unsure and fussy .Im happy with my purchase and would definitely buy from Dreams again ..Thankyou
It's a very comfy mattress.. but, it was very expensive compared to other brands (including memory foam types). The most annoying thing is that bed sheets slip off it all the time and we are constantly readjusting them (we've only just found out this is a problem with Tempur mattresses). Slight bit of buyers remorse but we're stuck with it for the next 5 or so years. You obviously don't try the mattress out with bed sheets on in the shop so I think people should be made aware.
I found the TEMPUR EASE 25cm SmartCool Mattress amazing. I have had sleep issues as well as lower back pain, but after using this mattress for a few weeks, my sleep has improved significantly and my back pain has eased.
Made my sleep better. No more back aches and shoulder aches.
Excellent mattress; comfortable yet firm, and a good nights sleep
Fantastic mattress, best night sleep ever wouldn't change it for any other mattress
After a hospital stay I wanted A more suitable bed. This was recommended . its perfect for my needs. Doss what it says ...
We purchased four tempur mattresses so that the family could all be comfortable and although I had my reservations, Im very pleased we invested as we are all sleeping like babies
After years of back ache we finally got round to buying a new mattress, I wish we had done it earlier. The Tempur Ease 25cm SmartCool is so comfy, we love it.
This product is a much pleased purchase along with the Tempur electric ottoman king size. They both go well together look great and is very comfy
Very comfortable mattress, softens within a few weeks but overall a fantastic purchase
Lovely mattress. So comfy, our aches and pains are gone since we started sleeping on it. Holds its shape well.
Ive been very happy with my Tempur mattress. Its comfortable, supportive, and great value for the cost. My backache has improved significantly since I started using it, and Im sleeping much better overall.
