I have yet to sleep on this so I can't review it for comfort. I bought this in store and when I unrolled it, it smells so terribly like fish, I don't know when I'll be able to sleep on it.

I give 5 stars for comfort but 1 star for coolness. It does have an odor upon opening, but goes away rather quickly. It would be a perfect topper if only it was cool.

[This review was collected as part of a promotion.] I purchased this hoping it would bring relief to my body from all the pain that hinders me throughout my day. At first I felt that it was going to be a waste, but as soon as it was unraveled from the packaging I realized it was a great idea. It came tightly packed and easy to set up. It also came with its own protective cover. After several days of laying on it I felt much better sleeping and waking up in the morning. The cooling sensation helps to treat my pains also. It’s not like all the other foam toppers you use that get hot after lying in the same spot. This one stays cool for a long period. Overall it appears to be very durable and won’t loose the memory of the pad. Also it seems like it’s going to last longer than any other brand.

[This review was collected as part of a promotion.] This topper is amazing. It comes with the pad and also a cover to keep it safe and clean. It was very easy to install, I put mine on, then gave it a little time to fluff up since it was vacuum sealed. After it perked up I put the cover on and my normal sheets. Then sweet dreams! I have told all my friends about how comfortable this pad is, would HIGHLY RECOMMEND!

[This review was collected as part of a promotion.] This topper has transformed an older uncomfortable mattress into a new one. Forms to your body and doesnt get too hot throughout the night. My son loves it and I had to give it a try to also see how it was.

I own this for over a decade and it is comfortable and held up well. My topper has started to break down and pill and I am looking another. I see people saying various toppers are too soft but they misunderstand what a memory foam topper is for. It's supposed to be soft and squishy and your mattress is supposed to provide the firmness. This is to fill in the gaps between your lower back, behind the knees etc.. that a firm mattress doesn't, it is not to refresh your mattress, though it will help.

This mattress topper is incredible. I bought this mattress topper to help with hip and low back pain and honestly didn't expect much but it turned out great. Obviously, it hasn't cured by back and hip problems but has certainly helped. It stays cool as promised and conforms very well to my body. If you're on the fence about buying it, just do it. I don't think you'll regret it.

[This review was collected as part of a promotion.] This topper feels like a cloud. Combined with an already comfortable bed, I can’t imagine better sleep. I highly recommend this product to everyone, good sleepers, bad sleepers, and anyone in between.

[This review was collected as part of a promotion.] My husband bought a mattress for our guest room but he insisted on getting a firm one for his mother. Unfortunately he didn’t get firm, he got hard as a brick. This mattress topper is the perfect combination of softness and coolness!
