Double/Full 12” Memory Foam Medium Firm Mattress. Purchased new Feb 2020 from Wayfair. Clean Removable Cover - Unzip it and throw it in the wash. Have kept it under mattress cover as well. Mattress is 12” thick and measures 53” by 74”. No box spring as used with a platform bed. Household is non smoking and pet free. Purchased a larger size mattress so I no longer need this. This is a clean comfortable nights sleep for a decent price. Pick up in Vic West.
