I couldn’t be happier with my purchase of the Serta 3” Cool Nights Gel Memory Foam Mattress Topper! From the very first night, I noticed a huge improvement in my sleep quality. The gel memory foam strikes the perfect balance between soft cushioning and firm support — it contours to my body without making me sink in too much. It feels like I bought a brand-new mattress for a fraction of the price.

Still end up with a hot spot underneath me in the morning

Made my old uncomfortable mattress very comfortable, but not cooling.

Very nice addition to my mattress

Not cooling at all. The total opposite. We sweat for 3 night and had to take it of.

Super comfy but felt i was sinking in the middle plus i was hot. Not cooling at all.

Made a firm mattress very comfortable!

Excellent quality. Doesn’t have a “cool to the touch” feeling but it doesn’t heat up under your body ! Highly recommend even for hot sleepers.

Nice mattress topper, but don’t find that it is cool. If you’re purchasing it for that purpose, I would reconsider.

The mattress is good. We did have to put a padded mattress topper on it. It was too firm for my son.
