It was on sale, so I decided to purchase.
Shipped quick and good packaging. It is vacuumed sealed, so be prepared for a flat foam. But, it conforms fast to 3".
I let mine sit out for 2 days due to it feeling damp.
Easy to put on bed, by myself, and it fit.
No smell at all. I did put a protector over it since my dog sleeps with me.
Feels different when sleeping on it. Took a couple of nights to get used to. Firm but soft if that makes sense. It is hard to turn over once you get settled on it. It doesn't sink in but does contour your body so, hard to move once you get your spot.
the edges are more firm than the middle.
It may be because I have a plastic protector over it, but it is HOT! No cooling effect.
I am happy with it so far for the price I paid.
