We're very pleased with this mattress topper.

This mattress topper is just the right softness/firmness for us. It has made our bed very comfortable. I've had less discomfort in my left shoulder while sleeping on this new topper.

I bought one of thes at Sam's Club for a spare bedroom and liked it so much i decided to get one for my room. Sam's no longer had them so was glad to find the exact same at Walmart .

Great Purchase

Love this. Changed our bed. Sleep so much better now. We have a king split adjustable bed. This is not just comfortable but took care of the annoying split in middle of bed.

Nice

The foam is not too hard, but not too soft. The cooling is so-so; like many products, you can feel the coolness initially and then it absorbs your body heat, which negates the product's cooling capacity.

Decent topper for the money

Thx topper isn’t as firm as I would like, since I have some back problems, but it is better than the tempurpedic one I tried. It is comfortable for most people. The 10 year warranty will never be used since it states it has to be depressed 1.5” before it can be utilized. If I waited that long I would have many more back problems.

The worst…

I wish I could give zero star… it’s cooling for first 10seconds then it’s not at all… we have back injuries and every morning we woke up with terrible pain of body. It’s bad but it’s even worse with this mattress.. I wish income return it but we are stuck with it. I don’t know how some reviews said comfortable. Maybe they never bad back injury.

Made my mattress even better. Relieves pressure on the hips. This is my second purchase as I’m placing it in the guest room. I can’t say enough good things about this pad.

Comfort and Cool Sleep

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.
