I rate this product poorly for a number of reasons: as stated in the product name, and not even 2.75 inches as stated in the product description. Its thickness barely reaches 2.5 inches. 2) I don't think it meets the "memory foam" criteria. ". This is regular foam. It's not very dense and won't retain a handprint even for a split second if you press your hand against it. The foam has a lot of elasticity, so the heavier parts of your body 3) Considering of the above, it's not worth the $70 I paid for it if I was expecting 3" real memory foam. If I knew it was 2.5" non-memory foam I would Expect $25 max. Honestly I think it's false advertising and I'm not at all happy with this bag on a hard floor that I used when I watched TV in my cave.
