This is one of the best buys/investments for the money. It arrived very quickly, in good condition, and the delivery men were very courteous. The instructions were easy to read and follow and in no time I had the mattress on my new bed. I had to wait 48 hours before sleeping on it ( per instructions that came with the mattress). My first time sleeping on my new memory foam mattress was like sleeping on a carpet of clouds and because I suffer from back trouble caused by a fall many years ago this mattress was very therapeutic.
