  • Amazing
Size: King Style: 3 Inch(with cover)
This foam is amazing. I needed this in my life. The elastic that is supposed to keep it from sliding off the mattress doesn’t really work well with mine (mine is really deep) It moves around a lot. The price is great also! I definitely recommend this foam topper however! I need two more.

  • Comfortable, right density.
Size: Queen Style: 2 Inch(with cover)
I wanted a mattress topper that would be comfortable and help with my backache. I like the density as it is not so deep that I can easily shift my body. It is comfortable, it doesn’t help with back and hip aches. Nothing does. Negative is it folds up at the top so I need to redo in morning, but does’nt affect how it feels. I do think it is a good value and one of the best toppers I’ve tried. ... show more

  • It's great, but with one caveat
Size: Full Style: 2 Inch(with cover)
In a nutshell: Getting some of the best sleep I've ever gotten, but there's one caveat. The 2" was a little too thin/firm for my taste, so I placed it on top of another regular 2" memory foam topper. Then it was perfect. Pros: The egg crate / swirl design really does help with air flow, and I find it much more comfortable than a flat topper. And the cover helps keep it cooler than it would be otherwise. Cons: It does get slightly warm, but nothing like the hot memory foam toppers I've had before. The cover really helps. Recommend to: Anyone looking for a quality memory foam topper that doesnt mind spending a little more, but who doesn't want to spend $100+. Bonus tip: the 2" would work well on a soft mattress. But if you have a harder mattress like mine, I might recommend the 3". ... show more

  • Comfy
Size: Twin Style: 4 Inch(with cover)
It arrived as a small package. After open it, I did another smell any strange smells. It’s a very valuable for 10inches high, not thin at all . also, I worry about the sponge, but when I lay down, it works very well. I didn’t hear any sound , very comfy.

  • WORTH THE THREE DAYS IT TAKES TO AIR OUT COMPLETELY
Size: Queen Style: 3 Inch(with cover)
This topper, like many, came tightly rolled and needed three days outside in the full sun to fluff up to its full 3 inches as well as to be completely aired out of its overwhelmingly strong chemical smell. I am sensitive to that, more than many, so it may not be as much of an issue for you. The cooling cover is beautifully made with very strong corner straps that accommodate a deep mattress. It is a tad warm but not overly so. I use it on top of a new mattress for added plush factor. I looked at many toppers and decided on this one for value, thickness and the material of the cover. I made the right decision. ... show more

  • Soft solution.
Size: Full Style: 4 Inch(with cover)
Very simple solution if you buy a cheap or bed a bit more firm than you expected. I bought a nectar bed. Felt fine at the store. Got it through Amazon. Was much rougher in person. This mattress top is a little tricky. Slides just a tad even with the straps but it does the trick and helps you sleep. Very affordable. Might be able to ditch out on buying many new mattresses in the future. ... show more

  • Not really 4 inches as ordered
Size: King Style: 4 Inch(with cover)
We like the topper but it is just okay comfort wise as it is not the 4 inch topper as advertised. This was supposed to be a replacement for the 4 inch topper we had on the bed. This expanded to 3 inch only as seen in pictures. I think if we had been sent the 4 inch as ordered, I could have given it 5 stars. ... show more
