I purchased this mattress as a gift. The innitial ad. for this mattress lead me to believe that it was solid memory foam through and through. Once completely to size (48 hrs) I could see that the mattress was one piece of Memory Foam 2.5 inches fused together with a soft but firm base foam. Very comfortable but not what I had expected. I spoke with customer service that evening via live chat. A man named Richie helped me, he could not have been more fantasic. He was empathetic to my concerns, he made me feel valued and he followed through with having a rep. call me the next morning. A gentleman named David called me, he handled my situation with great professionalism, honesty and absolutely did right by me. I will buy from Overstock.com forever! They are fast, honest and priced to sell! I have made 5 purchases since and have told all my friends and family how great they are! They continue to impress me with each order. This mattress is well made, very little odor (almost none now 1 week later) and firm yet soft with a well made zip on cover. This is a great deal and good quality, a great company to do business with. If you have any concerns, call them before ordering, they will answer all your questions! They are a great company!
