I topped this on the 12" night therapy mattress and it's the best sleep I've had in years. On my back, even. And I'm not a back sleeper or I wasn't because I couldn't, because I'd awaken with a hurting back. Not anymore. On my side, my hips no longer go numb or hurt. Love this topper!! And it's not hot.The cotton cover is ok, but I bought the Behren's England mattress cover for extra padding and it was perfect!!

I bought two of these for both of my boys who are teenagers. Their mattress pad works very well on keeping their body temperature cold at night so they don’t sweat. I also like the fact that the mattress pad comes with a cover. I would purchase it again if I have to.

My parents bought this as a Christmas gift for me and I have been sleeping on a cloud ever since. I love it! It is sooooooooo comfortable and gives me a great night of sleep.

I brought this 3 weeks ago and it is really comfortable. I enjoy it I had a 1.5 incnh mattress topper not the gel and it was ok this is so much better

Made a firm mattress feel soft and so comfortable. Usually my hips and shoulders hurt while sleeping but not with this topper. Best money I’ve spent in a while.

I ordered this gel topper to have back support without making the bed too warm. It is very soft so it doesn’t really offer much support, but it is comfortable and cooler than my former mattress pad.

I’ve been sleeping on it for a few weeks and still love it. Not sure about the cooling effect but it definitely gave my mattress the cushion I needed.

This topper helps us sleep better than before which was our goal. It's very cushy and relieves the morning aches we had before. I wouldn't want one over 3" thick, this is plenty.

We have a new mattress very firm and no sleep for me!!!! We bought the 3" gel serta mattress topper. It's fabulous the best sleep I've had it conforms to your body, and you sleep cool as it breaths..highly recomend it. We bought a king size

This topper made my bed feel like sleeping on a cloud. Instructions with it are a little vague. Be sure to put the waffle side up. If you don’t it will be hot. I found out the hard way.
