I bought a WDAchilles King size mattress From Mattress Depot It sleeps very unconfortable I wrote the warranty department several letters trying to get the situation taken care of , After paying Mattress Depot $1,399.00 for this mattress they want an additional $50.00 for someone to come out and inspect the mattress. They ask me to send in several photos attach with my receit and i have submitted all the information they wanted. but i refused to give them anymore money. The mattress i have only had 10 months .
