I have a King size 3 year old 22" thick Kingsdown mattress for sale. The mattress is considered a firm to medium mattress and has the foam pillow top on both sides of it. It's in excellent condition. I originally purchased it for around $4,500, and I'm asking for $1,000.
I had moved to an apt that does not fit a King size bed, therefore it is located in storage right now.
