i am selling my queen size mattress i have only had it for one years its in great condition, has no stains. I would like to add that i dont have the box to go with it but i do have the metal frame so it can sit off the floor while you acquire one, at this moment it sit in my basement covered so it stays protected reason why i am selling because i have bought a king size mattress,i originally bought it for $600, i would like to add that i cant do delivery but i can negotiate on the price
