I purchased this topper because my 5 year old mattress was feeling uncomfortable. I opened the package and noticed it had very little smell. That was great since I hate the smell of plastic. In 24 hours there was absolutely no smell and I placed it on my bed. The included cover is nice and keeps it from moving, especially when putting on the bottom sheet. Overall, the topper is nice, but I should have gotten a thicker size. It's comfy, but I just can't help thinking a thicker size would have felt even better. I've had it for over a month and it's already showing minor indentations where I sleep.
Had been searching for a gel memory foam topper for a full-size bed for our guest room. Having just had surgery, I was delighted with the comfort it provided during my recovery. It's very comfortable and not at all hot, which was a concern. I would definetly recommend. Great product for a very reasonable price compared to other brands!
