  • Happy with purchase
Size: King Style: 3 Inch
As described. It is thick and cozy. We slept well the past weeks with it. It only took a couple hours for it to expand and I didn't notice any smell. The size is perfect too. It seems it isn't cooling but not hot either just a little warm and I live in South Florida. However the material is solid so it can't be that cooling anyway. The memory takes a a couple seconds to reshape itself. It has fixed my pressure points when I sleep on my hip and back and the new mattress wasn't enough. It does not bother my minor back injury and I wake up with no pain. I keep it under the mattress protector and the material keeps it in place. If your like soft yet supportive you will like this one. ... show more

  • Great as Expected
Size: Twin Style: 2 Inch
I purchased the queen 2” foam topper. It fits perfectly over my queen mattress. The thickness is as expected. It comes vacuum packed and give it 24-48 hours to fully inflate. I did not notice any odor when I unpacked it. The topper is soft, I will be placing a mattress cover over top so it school not make us is hot and shld be breathable when sleeping. I do not know how one would be able to wash this if it became soiled maybe a spot cleaning would work but I have not come across this issue. I do not think it would be a good idea to place in a washing machine. I would say my sleep is consistent and comfortable . I would buy this topper again in future. ... show more

  • Love them!
Size: Twin Style: 2 Inch
I spent a lot of time trying to pick out the perfect mattress topper. Our girls have twin beds with very nice mattresses, but they were not comfortable. They were sleeping on top of their comforters, one was always hot, and thr other was sleeping backwards on her bed trying to get comfy. I didnt want to invest too much as they will be getting full beds once they are ready for their own rooms. These came folded over and rolled up in a box. Directions said to leave out to air out and gain it's fluffy comfy shape. I couldn't wait. They actually popped up right away. They had a light scent, not bad. I put em on top of their mattresses with 15 minutes of opening, placed the mattress protector and bottom sheet on top, and they were all set. Their pads and sheets are cotton. We haven't smelled anything. I picked out the two inch ones, and they are perfect. Our girls are happy, comfy, and sleeping in their beds like they are meant to be. Very very happy with this product. Looks just like the photos, and fits all around right up to the edge of their mattresses. Perfect! ... show more

  • The smell is AWFUL and it is not cooling
This topper is very comfortable and i love that it plumps back up quickly! I toss and turn and it doesnt take long for this topper to conform to new positions. It plumped up after about 4hrs out of the box. My only complaint is i am 3 days in and the smell is still awful! Like bad enough i removed it from my bed, had to wash the smell out of sheets, and it is now sitting in the spare room. Im hoping the smell will dissappear with a few more days. Also, i should add it is definitely not cooling! I had the topper under a bamboo cooling protector topped with cooling sheets and it was still very warm to me! So much so i turned on my fan lol. I gave it 4 stars because of the price point and the comfort. It definitely took the pressure off my back and hips. ... show more

  • Great great look no further
Size: King Style: 3 Inch
I’ve bought From Amazon for years! I never write reviews and overall I’m always pleased with everything I get on this platform, but this product was so deserving of a review! I work very hard and my body feels the grunt of it. I had a very hard bed and couldn’t get comfortable rest, I bought this. When I first opened it it was all squished and crazy looking! No worries! Let it air out! Most say 24 hours, it looked damn near full after 6 hours but I still let it stay out untouched for the 24. It is so comfortable best rest I have gotten. Truly feels like heaven perfect mix of memory foam and firm but not firm if you know what i mean, like it’s not cheap nor flimsy. Stop looking at other reviews and get this! 🥹❤️ ... show more

  • Great addition if your bed is too firm
Size: Queen Style: 3 Inch
I previously bought a mattress topper for twice the price. The foam was like regular foam with a colling 2" cover. Any ways what a disappointment. So I have now added this and it's great. My bed is very high now but this memory foam has made my bed comfortable. I use it under a mattress pad. This foam has the blue beads, holes and is responsive. The size is perfect for my queen bed. The weight is not to heavy, it's manageable. It's a great price right now at $59. I have a large rear end so before when I laid on my back the lower back had no support, now it does. My hips have stopped going numb. I do recommend this topper. One thing to note is that it does not come with a cover. Memory foam only. I use bamboo viscose sheets and a mattress topper on top of this foam so I don't have any complaints but not sure I'm a good judge on it. I do live in hawaii without AC so I do get hot but with this combo and a good ceiling fan it's ok. I would not call it firm. What I had was too firm, now adding this makes is just right! ... show more
