We have 6 double matresses brought years ago for our recreational barn for camp type sleep-overs but never needed! and want to donate? They have been stored, out of their plastic and remain in good shape but some have little discolor on the outside.

I don't know, Goodwill might be able to refurbish. Call and ask. You're asking the general public when you ask these questions on Google.

We don't take mattresses

If Goodwill doesn't take them call Salvation Army.

They generally take them. If not salvation army
