re: Sleeper sofa - yay or nay

We had one in the living room when we lived in a 2BR townhouse and it would get used a few times a year when we had guest/family staying over, it had a memory foam mattress so it was comfortable enough to get by. Like mentioned they're heavy but it's not like you're moving furniture around often, though I wouldn't want to deal with having to get one up to a second floor. We moved and ended up selling it as we replaced it with a sectional without a sleeper.
