Looks can be deceiving! I was definitely not happy to see it when I opened it.  It was small, vacuum packed and did not look right product.  I was so wrong!  Once I let it out for a day, it gained its size and got to the shape and size.  It is thick, sturdy, and hold the shape.  It put it  on the carpet and slept on it for the night.  It felt great and was quite surprised.  It works well on top of the mattress as well.  No smell, well packed, great price for the product.  Highly recommended!
