I read numerous reviews before deciding to purchase this mattress topper . . all I can say is, "Why the heck did I wait so long?" This topper is fantastic. Even though I purchased it at the tail end of Central Texas summer, It feels cool and comfortable. This is really a fantastic find - I love the gel and fiber blend because it's the perfect combination of comfort and cozy without overheating. Other reviewers noted a chemical smell but I didn't noticed anything when I opened it up. I also followed the advice of other reviewers and left it unused for a day or so to fully expand. I've got ZERO complaints, this was a top notch purchase and I couldn't be happier.
