Received my mattress in a matter of a few days. Per instruction, I opened up the package and allowed the sufficient time required for the mattress to expand; however, it fell about 1" shy of the stated size, which was promptly taken care of by Overstock's excellent staff. There was no noted "odors" from the mattress. Having slept on the mattress now for about 1 month, I find that I am getting a much better night sleep than on my old spring mattress. This is my first foam mattress, but I would highly recommend this mattress to anyone who is looking for a "really" good night sleep, and highly recommend Overstock.com for their outstanding merchandise and very helpful and knowledgeable staff.
