i am going to redo my room and was wondering if a sleeper sofa would be comforatable if it had a memory foam matress,
I've never been a great fan of sleepers, primarily because the bars are HORRIBLY uncomfortable regardless of the mattress you're using. I saw some time ago in a catalog, a product that you put under the mattress that was supposed to stop this from happening, but I can't remember what it was called. You might be able to find it in a store however. A good alternative is either get a futon or an air mattress (we actually have both). The only thing I CAN recommend for sure is that if you do plan to get a sleeper, go to Jennifer Sofa. They have the very nicest, most durable products I've ever seen, and they're very affordable.
personally I'd suggest a comfortable sofa with removable back cushions. The seat cushions will then be nearly 26 deep and will easily sleep one. For larger crowds, an air mattress (yes, eventually they leak) but an air mattress used once in a while is better than the discomfort of sitting on the end of a sofa bed. Close to the arm, the mechanism is too hard and you'll lean in. Get a good sofa and a blow up mattress even a fold down futon is better than a mechanized sofa bed, for my money... imho
Better, okorder /... if modern and twin work for you.
It will certainly be more comfortable than the traditional sleeper sofa mattresses. That is, if the foam is thick enough. It really depends a lot on the construction of the frame underneath, too because that is really what you feel with a traditional mattress.
