Can you use a futon mattress on a sofa bed?
if it is one of the 4 ones i have one on mine it will go into the couch and work. in needs to fit the frame of the bed it can not be to big it will not go into the couch if it is too big
You will have to measure both to see if it would fit since futons are the same size but sofas are not. Also you would have to see if the place the mattress folds is at the same place the sofa will be matching that fold.
