I have to say I'm one of those people that put a lot weight into the reviews that people write. When I was shopping for a memory foam mattress topper I was concerned about the size because many wrote that the topper they purchased was about 3-4" small all the way around the mattress(I have a king)and I was concerned about the possible smell and quality of the memory foam. First of all I got my topper within 3 days. I opened it and let the foam expand for maybe 5-6 hours. It expanded to exactly 2" just as advertised and it fit my king mattress perfectly from corner to corner. The quality of the memory foam is superior and the air holes allow for a cool comfortable nights sleep! Best of all, no smell at all. It makes my bed look and feel like a new top of the line pillow top. I certainly recommend this product to anyone considering a memory foam mattress topper!!!
