After sorting through many reviews, I decided to purchase this mattress topper. I am new to the world of memory foam, so I was a little scared at first. After reading that it could possibly smell for weeks, or be way too hot, I was really hoping that I wasnt throwing my money away. It arrived in the mail and I quickly started to unwrap it. I let it unfold naturally (like everyone suggested), and let it air out for a few hours. There was basically no smell after 3 hours!! I was using it that night. It is the best! I am far happier with this purchase compared to the $800 I just spent a few months ago on a new mattress. I love the egg crate feel too. It is the best purchase I have made all year!!
