I have a 2 year old sealy posturepedic mattress king lindwood springs firm mattress for sale. It has had a zipper style cover on it for the entire time (air proof). Comes from a clean home (you will see if you pick it up) It cost $2,200.00 2 years ago. It is in very good shape. Reason for selling. We had to replace it with another one due to a new back situation. Everyones back proplems require a different style mattress. local pickup only. local Delivery available for gas.
