Are twin sleeper chairs comfortable enough for the occaisional weekend guest?
Not especially. The portable comfortable is likely a futon. Some can be found that fold into a utility table.
I have a chair and a half, meaning it's longer than a regular chair, but not as long as a love seat. It pulls out to make a twin bed, which our daughter has used. It's the best of both worlds if you have room for it. I bought the matching ottoman, which holds blankets, sheets, candles and a few other things.
