Ikea king size mattress. (Frame not included) Purchased 6 months ago . Mattress is in brand new condition from a smoke free and clean home. The mattress has had a mattress cover on it since day 1. Only reason for selling is after 6 months of use we have still not gotten used to the firmness and have ordered a new mattress, that is less firm. Paid $805 taxes in 6 months ago. If you are looking for a firm like mattress in King, this is your best affordable one.. Price is $450 OBO. Thank u for your interest
