We are getting rid of the bed in our guest room. DH hates it but I actually like it. It's maybe 7 yrs old. He wants to give it away. If it's a friend, I don't mind doing it cheap but it's still worth something & we need to buy a decent futon or air mattress for MIL & my grandmother. So any $$ would help.
Re: How much to sell a full size mattress, box spring & frame for?
It all depends on the quality of the mattress/boxspring, what you paid for it originally and how much use it had.
I would think maybe $100
