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.

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.

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.

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.

This mattress topper is so comfortable. I sleep so much better, whether on my side or back. Definitely worth the purchase!

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 .

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.

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.

We decided to purchase this topper even though a review had warned of the foul smell. Once opened, the awful smell permeated the room. It smells of death and soiled diapers. I do not know how anyone would willingly put this on their mattress. I called customer service to return and was told it had to be picked up. I was told I would receive a call to schedule the pickup. Later that day I received an email with a return label for Fed Ex. IT IS IMPOSSIBLE to place back in original box. My husband had to buy a big box from a storage company to be able to send via Fed Ex. Please save yourself the time and aggravation and DO NOT PURCHASE.

I've been using this memory foam topper for about a month now and it's just what I needed. My mattress is too firm and I was considering buying a new one because my back would often times hurt when I woke up. I decided to try this memory foam topper and it's done the trick. It provides the support I needed for my back and its very comfortable. I rarely do reviews, but wanted to share my success with this topper.
