  • Very comfortable, give it plenty of time to initially decompress
Size: King
It's great!! Soft, comfortable, fits my king size bed easily. It comes rolled up and compressed in the package, but once you open the protective plastic cover, it starts to "inflate". It will take up to 48 hours to fully expand, and once it does, it's gold to sleep on. I got it early in the morning, and pulled it out of the box, and was pleasantly surprised to see it included a flat strap cutter style letter opener to cut open the protective plastic with. It's taped to the plastic, NOT inside it. Of course you can use a pair of scissors if you're careful. One thing about uncompressing it, you can open the zipper all the way (the cover is removable for washing), and it will help speed up the initial process. I put it on the bed to decompress about 10 AM and about 12 hours later it was well on it's way to being fully uncompressed. I did sleep on it and it was comfortable, but now, a week later it's fully uncompressed and comfortable as all get out. Sleeping very well now. Can highly recommend this topper if you're looking for one. ... show more

  • Is super soft in the right places!
Size: Queen
At first I was kind of thrown off on how it just squishes down super fast. But as I begin to sleep I found it was very comfortable for my knees it didn't sink in it just sank in and my heavy spaces my back! I didn't have a smell when I opened it. It looks very durable and you can take the cover off and wash it if need be. It fit right on top of my queen size bed with no problem. I think it's a great value if you understand how it works. Soft in the right places but you can sink down in it and get lost 😂. No seriously when I sleep I don't have pain in my legs or my shoulders anymore. ... show more

  • Worth every penny!
Size: Twin XL
This was a college dorm purchase and definitely one I would purchase again. My daughter says her dorm bed is more comfortable than the bed at home now.

  • Super comfy
Size: Queen
Very comfortable. Perfect fit for my queen size spare bed. It absolutely hides any “coils” that might be poking you. Prevents you from having to buy a new mattress. Great purchase!

  • Clouds Clouds
Size: Queen
Definitely recommend for those who have a firm mattress and are looking to have a cloud feeling. You sink into it and it hugs your body so nicely. As far as when first opened you’ll feel like you got ripped off lol because it’s so thin and looks terrible but once it firms up within 30 minutes to an hour it really is 3 inches and looks amazing. Worth the purchase! ... show more
