Best sleep ever!

I bought this topper for my 18 year old sons mattress. After sleeping on it one day he told us it was “the best night sleep he ever had”! Needless to say he loves it! He is an athlete and needs a good night’s sleep to recover. This was an excellent purchase!

Good Topper

We have an 18" King mattress and were worried our sheets wouldn't fit but our Giza cotton sheets fit right over it. It's comfortable and not as hard as a former foam topper we had. It really doesn't have much of a noticable cooling effect. We did have our heavier mattress cover on it, instead of the one that comes with it. We thought that might be the issue with no cooling and changed the covers out. But, there really wasn't much of a difference. Also, I am very reactive to smells and it really didn’t have any type of chemical oder. It fluffed up in one day and we slept on it that night. All in all, a good product at a good price and it saves us from having to buy a new mattress for awhile.

Don’t think twice about this! Just do it!

This bed topper is absolutely AMAZING! The foam is so soft, yet so firm! The cooling effect is my favorite part. There is a noticeable different. This took my bed from 10 to 100! If you’re looking for a sign to just buy it, this is your sign! Your back will thank you!

Great addition to my firm mattress - no back pain

I've been using this memory foam topper for about a month now and it's just what I needed. My mattress is too firm and I was considering buying a new one because my back would often times hurt when I woke up. I decided to try this memory foam topper and it's done the trick. It provides the support I needed for my back and its very comfortable. I rarely do reviews, but wanted to share my success with this topper.

Mission Not Impossible

It’s amazing once you get into the bed. Getting into it is a mission though.

No pressure point numbness

Very comfortable. Reduces tossing and turning and has eliminated pressure point pain.

The sinking topper

This has 0 support, and you feel like you're sinking all night long.
