This is our first memory foam mattress, and we bought 2 more for the kids. Very comfortable, and great for our aching backs. As soon as all the other mattresses die off, we will replace them with memory foam. Delivered straight to our door, and my husband and I could easily carry them. They unfold and puff up and are ready in less than a day. About a day of "new foam" smell, but it's not too strong. If you are the type of person who likes to sit on the edge of the bed and put on your shoes, there is no reinforcement around the edges like regular mattresses, so you'll slide right off. That's the only down side I see for other folks, but not a concern for me so I still give this product 5 stars.
