I purchased the 3" topper 6 weeks ago as a solution to my uncomfortable bed. I noticed an immediate improvement. Here is a list of my observations so far. * The mattress topper is soft but firm enough that I don't feel like I'm sunk into a hole. * I don't feel a 'cooling' effect But, It does not retain heat, which is perfect for me. I also have a mattress pad over the topper, which I will remove once the nights get warmer. I will update if I notice a difference. * It took my body a few weeks to adjust. At first, I woke up with neck pain. I realized that my neck was positioned differently and that I needed a different type of pillow than I used without the topper. No more neck pain. * I was nervous about this purchase because I've had bad experiences with toppers and mattresses in the past. Sam's Club return policy have me the peace of mind to give it a try, and I am so glad that I did. * I recommend rotating the topper regularly.

Could not turn over!

Received damaged. I ordered the king size, so, as you can imagine, it’s quite heavy. I had it delivered to my home. It’s not in merchant packaging. It delivered in a brown box, vacuum sealed. As I get this out, remove the vacuum packaging, as I get to the last portion unroll, it starts expanding and there, on the inside portion/side is a a huge chunk missing from the topper, which looks like a manufacturer defect. Now, after calling and going through the horrific automated customer service to figure out how to return this because it will not fit back in the box, I now have to wait for a return service to pick this up and figure out where to stash a heavy, king sized memory foam topper u til they pick it up! What a nightmare!

I bought it for my guess room its super comfortable

At first, I wasn't sure. It took a few weeks and now it is perfect!

Can take any crappy mattress and make it feel like a cool cloud. I'm about to buy my 3rd!

Bought to add to top o camper matress.

I don't get a clear cooling effect. The topper is 2 inches short on both sides and ends

We love this mattress pad, saved us a lot of money on replacing our mattress.

Item came as described and fit a california king sleep number well.
