I ordered this mattress topper for my mother. She was about to go out and spend over a thousand dollars on a new mattress and this was stressing out my Dad who didn't want to spend the money. They were fighting like crazy about it. But my Mom kept waking up sore in the mornings. I came for a visit, and suggested we get up on Overstock and take a look at the mattress toppers. I have one of the bigger ones (8"), which I absolutely LOVE. I had read the reviews on several of the thinner ones and was convinced this would be the ticket to a comfortable night sleep for my Mom and would make my Dad's wallet happy too. We ordered the topper and it came in just a few days. There was literally no smell which was great (my mattress had some of that factory foam smell, so I was really pleased about this). My Mom only let it "puff up" for about 2 hours and slept on it that night. She practically cried....she LOVES IT!!! She says its the absolute best sleep she's had in years....And of course, my Dad is thrilled. The best part is, they have stopped fighting about the stupid mattress issue. Problem solved. Both are happy for a measly $129. I wish more people would look into these toppers before they chuck out old mattresses. I think they are the coolest inventions ever. Thank you Overstock and thank you Serta!
