I mostly hate sleeping on people's sofabeds, especially with DH as they are narrow and you can feel the other person breathing etc. We have a tiny 4th bedroom which will be the guest room, and will need to accommodate elderly inlaws. We are looking for something that is max 1.98m long and max 1.84m wide when open, and preferably 1.84m wide when shut, but that is going to be good to sleep on. My choices seem to be 1) a trifold futon (practiced on these at the Futon Company and they were rickety) 2) a single bed with another one underneath which comes out and up to same level or 3) a narrow sofabed. Option 1 or 3 would look best when bed not in use, i guess, but i imagine 2 might be comfiest. the room never needs to be 'sat' in, just slept in, but that probably won't happen more than once a month. Any ideas?
