The Coolest, Most Comfortable Sleep of My Life

The TEMPUR-ActiveBreeze® has been an absolute revelation. I've always slept hot, and this mattress has completely solved that problem — the active cooling technology keeps the surface noticeably cool all night long. On top of that, the pressure relief is incredible. I no longer toss and turn, and I wake up without any of the aches and stiffness I used to have. The build quality is outstanding and it truly feels like a premium product. After just a few nights, I couldn't imagine going back to any other mattress. If you're a hot sleeper looking for the perfect combination of cooling and comfort, this is it.

Good

Not as cooling as expected, it warms up pretty fast. It also takes longer to comeback to initial form (we bought the medium hybrid)

Very, very, very, very firm

This review was collected as part of a promotion

I’ve had, and loved Tempurpedic pillows in the past. I purchased this one as a replacement for one that I’ve had for a few years. This one was not even close to as comfortable as previous versions. It’s firm to the point of being uncomfortable. I have loved the neck support and just the right amount of “give” in my older versions. There is neck support, but NO “give”. I wanted to love it as I have done in the past but after only a few nights, this one was retired to the closet. Since it cannot be returned, I’m stuck with a brick.

Better sleep

I ordered this topper because our old mattress was too hard for my side sleeping position. When I added the topper I was able to sleep much better.

Very comfortable!

Bought the topper to soften a memory foam mattress that was too hard and difficult for me to regulate my body temperature. This topper is great - it's relieved pressure points in my back and my husband's hips and I rarely have issues with body temperature.
