This is the BEST memory foam mattress topper I've ever had. I bought a 2 inch in a twin for a cot we were using as an extra bed and everyone went crazy over how comfortable it was. I loved it so much I purchased this one for my full size bed, but in a 3 inch. It is a total game changer. I want one for every bed in the house. These toppers are excellent quality. They come rolled up, but take no time before they are to size. They do not have a bad odor like most others tend to. I have had improved sleep and it has helped my hip and back pain so much. I wake up feeling better. The 2 inch is great, but I'm loving the 3 inch thickness. It seems to support me a bit more. It's such a great value and worth every penny! I LOVE this topper!

I bought this for the guest bed and it seems to be quite comfortable. I've had it for several months but it's not used that much, so I can't speak to how well/ long it will hold up. It fits the bed perfectly and doesn't slide around. I would recommend it so far.

Been using for 3 full months, didn't want to rush the review due to mixed reviews. I bought the twin xl size, and I weigh 200lbs give or take for reference. Did not have any of the durability or smell issues that other buyers reported. It is a medium firmness, I still think it feels soft, compare to a hospital style mattress. Definitely hardens if it's very cold, like most foams, so that is to be expected, but it's definitely not a true memory foam, bounces back to shape within 3 seconds of getting off it, and does not pass the "shake" or bounce test for spilling liquids like most true memory foams would. Cleaning instructions say to spot treat only, so definitely cover with mattress protector. Mine has some minor sweat stains after 3 months of use in hot weather. Gross, but not the fault of the manufacturer. All in all... good mattress topper, good value for the price, my girlfriend enjoys it also, although she prefers super firm bedding materials typically.

It gets warm, perhaps not as warm as some but I’m used to that and I’m ok with it. It puffed up immediately and had a slight offgassing odor. It’s looks good and has no flaws to see. I left it in an unused bedroom for a couple of days and it quickly lost the smell. It felt firm at first so I was concerned about too firm but no, when it warms up with me in it ..sinks a lot. I was concerned at first and not too sure about that but it’s working out well. Laying down in bed at night is very comfortable. I think I would prefer less of the sinking in where my heavier parts are, but. Gel does that. I weight 129 lbs and I’m short so, if you’re a larger sized person, it might sink in too much and you would need a denser topper. Overall I’m pleased and I’m keeping it and sleeping on it. If I decided in a few weeks down the road , that I would be better off on another topper, i’ll adjust my rating.

Worst mattress topper I’ve ever bought. 1st: The sizing is way off. It hangs way over on the corners making it impossible to fit even a deep pocket sheet set. 2nd: It is extremely HOT and NOT breathable WHATSOEVER. Even with a waterproof mattress pad and a sheet, I was sweating profusely. 3rd: It is not slip resistant. I felt like I was riding a slip n slide all night long, water included! The return instructions say I have to BOX IT UP. NOT ideal since it came to me vacuumed sealed. I am not happy

This new topper unfortunately isn't for me, I hate it have to ask for a refund, it is too to soft. I sink all way down , causing my back to hurt. If you like soft this is the perfect mattress . I say the cooling appearance and the is good and the overall appearance .
