Ok, everyone wants to read the perfect review for a bed topper. I had bought a 4" topper thinking since I'm a larger guy I would need the support. Truth be told, it was too thick. I was bending like a banana. I bought this 2" topper praying it would be better. I suffer from back and neck pain. This is by far the most comfortable and restful sleep I have had in a VERY long time. When I opened it, there was hardly any smell. Since I've had it now for about a month, I still don't smell anything. I actually look forward going to bed. This topper is NOT HOT!!! It breathes. I live in New Orleans with means HOT AND HUMID. Anyway, if you're wanting a bed topper that will help you sleep, rest, AND not be hot, then look no further. This IS your bed topper. Hope you enjoy it as much as I do.
