Bought this mattress to replace a 10 year old traditional mattress.  So far so good!  Used to wake up with backaches, haven't have any soreness since using this new mattress.  Also a WONDERFUL price.  We looked at mattresses that were double the price.  Also really liked that this was available in 14 inch size so it really feels like a real mattress.  Some of the other memory foam mattresses that were not at thick feel like a cot mattress.  

Pros: super fast shipping, great price
