    • 9 months into sleeping better!

This has been a great memory foam mattress topper it is dense and supportive yet soft and comfortable. Even if you run hot when sleeping you’re not overheating, its not breaking down and it’s been 9 months and hasn’t broke down and still as supportive as day one it’s pure comfort!

    • Comfortable but maybe not cooling....
Size: Queen Style: 2 Inch
I bought the 2" queen topper. It came in a box and rolled up in plastic. I opened it up and laid it flat for the recommended 24 hours. It had absolutely zero smell, which I was pleased about. I added it top a firm mattress. It did make the mattress more comfortable! However, I definitely don't think its cooling advertisement is correct. I am never hot over night and found myself sweating twice! I'm hoping it's the new bedding I added instead of the topper and will try just a sheet tonight. I will update my review if that doesn't help. Overall, nice product. Fits on my queen mattress well. It was easy to lay out on the bed - though it does move a little when putting tight sheets over it. Definitely improved the softness of my very firm mattress! ... show more

    • A great night sleep
Size: California King Style: 3 Inch
Favorite new purchase! This is so comfortable! I have been waking up feeling refreshed with improvement in my back/neck pain and have only had this 4 days! The set up was a breeze and was ready for sleep the very first night.

    • Not as Advertised
Size: King Style: 3 Inch
The intent of this mattress topper was to help soften the firmness of my mattress as my mattress causes me lots of pain when I slept on my sides, mainly my hips . It has been about a week since I slept on this mattress topper. Not only the pain on my sides has not changed, but I have gained additional pain on my shoulders, which is excruciating. My neck is super stiff with a constant headache. Overall, I am in more pain now than I was 1 week ago. I tend to sleep in the middle of the bed. The mattress topper is slightly indented already. To seek a little comfort, I start out on one side of the bed and slowly moving across the bed in the last 3 nights. Tonight, within 4 hours I trekked across my bed and now I find my couch provides better comfort than my bed. This couch has been in the family since the 1980's. Sleeping on this mattress topper has been worse than sleeping on my firm mattress. I don't even know how to return this mattress topper. It's bulky. I will probably have to cut it up into smaller pieces to dispose it in the trash can over time. I guess it's better to spend the money to replace the entire mattress than to waste money seeking out different mattress toppers. I truly fail to understand why this mattress topper has so many high reviews. BTW, I am 5'4" and weigh 123 lbs. Therefore, I don't think my weight has anything to do with how the topper fails to support my weight and already has a slight indentation. ... show more

    • Doesn't work for side-sleepers if your mattress is too hard
Size: Full Style: 3 Inch
My 10+ year old mattress got so flat and hard, it was giving me pain all over my body, mainly my hip bone and shoulder (that presses against the mattress). I bought this mattress topper hoping that it'll soften my mattress and relieve the pain. Unfortunately, it didn't help with side sleeping. It inflated pretty quickly within 2 hours. I still waited a full 30 hrs before using it but I could tell it was too soft. If I push my hand on it with barely any pressure, it immediately sinks to the bottom with no resistance. Needless to say, when I lay on my side on it, my hip bone goes straight to the bottom against my rock hard mattress and my hip bone still hurts. It didn't relieve any pressure. I'm only 135 pounds so it's not a weight issue. I don't quite sink to the bottom on my back though so I'm forced to sleep on my back now. Sleeping on my back, it's comfortable enough, like sleeping on a cloud as some ppl say. However, I'm not used to sleeping on my back so my sleep quality hasn't really improved yet. Pros: Low price Restores shape very well (fully inflates again after I get off of it) Comfortable for back sleeping (sometimes my back hurts but I don't know if it's related) Can move around easily on it (reviewers for other toppers said they can't move around on toppers) Cons: Too soft/thin for side sleeping (didn't relieve hip pain, my hip goes right through it) Sleeps hot (I wake up sweaty almost every night) Has a smell (not super bad but took 2-3 weeks to go away) Overall, it's a decent mattress topper for the price, but it didn't relieve my hip pain. If you have a rock hard mattress like me, it helps if you sleep on your back, but not on your side. It's better than nothing but I want to try a higher-density one. ... show more
