The memory foam is s-l-o-w to self inflate...we watched it grow for four days and hope it will be ready to put on the bed next weekend. The portions that have expanded to 3" look and feels good.

I think this has been stored in a warehouse at extremely hot temperatures and it has melted into its compressed state. Ive had it laid out for a week now, and only a few spots have expanded. Most of it is firmly compressed down. EDIT 2 weeks later, it is ALMOST expanded enough to put on my bed. Getting tired of tripping over it on the floor, hoping to actually use it soon.

I love this topper. It is like sleeping on a cloud.

I ordered a Linenspa Essential 3"topper. I received a Lucid topper instead. I believe the Linenspa cost about $10 more. Decided to keep the Lucid topper anyway because I don't want to wait another 6 weeks for delivery of a new one!!!

Overall very pleased!
