Love this Memory Foam Topper!! Arrived earlier than expected too..I ordered on July 8th in the evening and received it on the 11th that afternoon!! It's very thick, but very comfortable!! I actually overslept for work this morning because it's so comfy!! It came compressed in a large box but was plumped up within 20 minutes of opening and laying out on my bed...it did have a slight odor but disappeared after about an hour. I may purchase sheets with deep pockets because of the thickness,  but was able to stretch my sheets this time....Very happy with our purchase!!
