Size Matters

So comfortable

[This review was collected as part of a promotion.] I have had this cooling mattress topper now for over a year, and it is amazingly soft and durable! I also love the cooling effect it definitely works.

Incredibly soft

influenster.com

I love this matress topper. My very firm mattress is now softer and much more comfortable. I no longer wake up with shoulder or upper back pain.

Comfortable - Exactly what I wanted

walmart.com

[This review was collected as part of a promotion.] I loooove this product. I’ve always been more a firm bed sleeper but this was such a nice surprise! It was super dreamy to sleep on this. It had the general characteristics of memory foam without being too squishy and still provided plenty of support. The cooling cover was also such a nice addition because it kept me cool and comfortable.

Dreamy sleep!

Sealy

It is a nice thick mattress topper, however, it does not appear to be gel, nor is it cooling!

Thick- Not Gel- HOT

[This review was collected as part of a promotion.] This mattress topper is soft. It was quite heavy when I was trying to move it on my bed. As far as keeping you cool it didn’t really do that BUT I did get really cold at night and I don’t typically get that cold. With this be memory foam I did sink in a little. The topper did add extra height to my mattress.

Soft but not really cool

[This review was collected as part of a promotion.] Well let’s say that I already have a Sealy mattress which is fabulously soft.   This topper does firm it up a bit and that’s a good thing.  I have a bad back and I need something to help me have a better nights sleep.   I cannot really tell a difference in any cool feeling but to be fair I live in Georgia and it is already hot here.  The topper is comfortable.  It does make the bed higher which is not an issue for me but my cats are not a fan of it.  I’ve been using it for almost a week now and I’m curious to see how I adjust to it in another week and so on and so on.  But a really good comfortable soft but firm topper.  I could see having an old mattress how this would truly help.

For sure a nice topper with the Sealy name

[This review was collected as part of a promotion.] I like that it is soft I would say it is tooo soft and I’m used to sleep on tough mattresses. This mattress topper is great for people with back pain and my mom took it with a smile. However at night you can easily fall down

Too soft you can fall down

[This review was collected as part of a promotion.] I always have a difficult time sleeping. I wake up multiple times a night along with toss and turn. I wanted to love this mattress topper so badly and was extremely excited about it.  When I laid down on it I sunk in. I could not get comfy and after an hour I started thinking I'd never fall asleep. I removed it and went to bed. I tried napping on it another day and had the same problem. I honestly hate it. I guess I'm not a foam mattress sleeper.

Not for me
