This topper does stay cool unti morning. It also gives enough support if you place it on your mattress waffle side down. Be aware that you may need a deeper pocket sheet because of the added thickness if the topper.

I bought a new mattress a year ago and it was just too hard. My hips and low back hurt every morning & my sleep was disturbed by constantly repositioning during the night. This gel topper has solved my problems. No more pain and interrupted sleep.

Bought this online and it arrived on time, were no odors or anything wrong when unpacking. Easy instructions to install on bed and within one day topper was fully expanded. Love how it sleeps and I don't sweat on it like the cheaper ones

I expected to have to get used to sleeping on the Serta 3" Gel Memory Foam Mattress Topper but I was wrong. I got the best night's sleep in years the first night I used it. I highly reccomend this product.

Love it... Like sleeping on a feather bed...

Wonderful, love it. Really made a difference on our bed.

made a very firm mattress comfortable

This is much too soft for my tastes.

I bought this less than a month ago, I'm very satisfied.

Just what we needed, really great, worth the money
