Queen Memory foam mattress and split metal frame

Queen size firm mattress. Heavy duty steel construction base. Fully assembled. Maximum weight 1000 lbs. No frame needed. Only used for 2 weeks by one small person. A bit too firm for me. It is very comfortable to lay on and has great support but I wanted something plusher. Nonsmoking very clean home. Always had a waterproof cover on it. Option to take a particle board cut to size for top of base.
