The worst

Absolutely no support from this mattress topper Tried it half a nite and when i tried to get out of bed my back was in such pain i could not walk. Took it back and was happy to get my money back.

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.

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.

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.

Good Topper

We have an 18" King mattress and were worried our sheets wouldn't fit but our Giza cotton sheets fit right over it. It's comfortable and not as hard as a former foam topper we had. It really doesn't have much of a noticable cooling effect. We did have our heavier mattress cover on it, instead of the one that comes with it. We thought that might be the issue with no cooling and changed the covers out. But, there really wasn't much of a difference. Also, I am very reactive to smells and it really didn’t have any type of chemical oder. It fluffed up in one day and we slept on it that night. All in all, a good product at a good price and it saves us from having to buy a new mattress for awhile.
