Game changer...wow impressed
Size: Full Style: 4 Inch(Grey Cover)
This is absolutely amazing, you feel like you are laying on a fluffy cloud. We purchased a king size for us and full size for our young son both the 4 inch thick with the gray cover because of how amazing ours is. My husband and very bad back pain to the point where he has trouble getting up in the mornings and this has just been such a game changer for his back. he has slept so much better and his back pain continues to majorly improve. it is not hot and truly does live up to cooling sensation it claims to be. The straps are great and keep it in place without issues. If you have a doubt about purchasing this, I hope my review helps because it truly is great and I highly recommend it. Let me just put it to you like this, you will have a hard time getting out of bed but because of how comfortable you will be. ... show more

Sleep Game Changer!
Size: King Style: 4 Inch
The new setup with the cover and straps is amazing!! I recently ordered a new one because I’d had my other one for a while. I absolutely loved it, but I wanted a fresh one. When the new one first came in with the cover and straps, I thought I had received the wrong thing and was going to send it back. Then, overnight, I realized that it had all of the amazing comfort of the original, but now with a really great upgrade!! My elderly mother recently came to visit, and I have the 4-inch topper on the guest bed. She said she had never slept so well! Her shoulders and hips often get very uncomfortable at night, and she was amazed at how much more comfortable she was. She was so grateful to have discovered this topper and is now ordering one for her own home! ... show more

Wonderful!
Size: King Style: 4 Inch(White Cover)
I'm so happy with this thing! It made an unpleasant mattress totally comfortable. Fluffed up really quick, like 15 minutes. The straps are great too keep it in place and it's awesome that they are adjustable for different thickness matresses. Very happy with it.

Terrible smell
Size: King Style: 4 Inch
Very soft and thick, i was hoping for a little more firmness but thats a gamble anyways when ordering online. It had a very strong chemically/moldy smell to it which made me very nauseously hug the toilet and spend the night in the guest room. I hope it fades soon because it seems nice otherwise. Update: i‘ve had it for a month now, the smell went away after a week and its been very comfortable and i would buy it again. But they really gotta air out their factory more that smell was atrocious ... show more

No longer toss and turn
Size: King Style: 4 Inch
Review Image by Kristina
Made an uncomfortable finally comfortable! Slight odor when you unwrap it but that's to be expected. No longer have back and hip pain at night from tossing and turning. Feels nice a fluffy without being to soft so it's still got great support.

Perfect solution for an overly firm mattress
Size: King Style: 4 Inch(Grey Cover)
Super comfortable. I had purchased the previously listed version of this topper so I already had high expectations. This turned a rock hard bed into the perfect firmness. I got the four inch version and I don't sink into it nor do I have difficulty moving. This was on sale when I got it making it even better. It fluffed up to full size within an hour of opening it and it had no odor. I opened the cover and initially thought it was damaged but within an hour any squished areas were totally inflated to their proper size. ... show more

The quality of this mattress topper exceeded my expectations.
Size: Full Style: 4 Inch(Grey Cover)
I haven’t written many reviews, but this product definitely deserves one. I’m very impressed by the quality of this mattress topper. I did order it with the cover because I wanted to protect it. Plus, I have a mattress cover over it that is spill proof, and then my sheet. I bought this to go on top of my very firm a full size mattress. It fits perfectly and was so easy to put on my bed. I have to say this thing is amazing! It puffed up completely within a couple of hours. Once I had it on my bed and my bed made I just had to take a nap to see how comfy it was. It was extremely comfortable! I’ve had a few toppers, but never one as comfortable for the money. I had one that I paid over $100 for that was nothing compared to this. At the time I purchased this I paid 70 something dollars and that included the cover. I think it’s a great value for my money. ... show more

Best nights sleep in a while!
Size: Twin Style: 4 Inch
Update: after sleeping on the mattress topper for about a month I can honestly say it is pretty comfortable, the only real downside to this topper is with it not staying in place on the mattress, it moves from side to side, I am constantly having to pull it back into place on the mattress which gets annoying, live and learn I guess. This topper too pretty much the full 24 hours to totally expand but it did, this topper is well worth every penny, very comfortable, great support, best sleep I have had in a very long time, this topper will add years of life to your Mattress, we have a Mattress topper on the bed of our travel trailer as well, without a doubt this product is a game changer. ... show more
