Sleeping on sofas is a dangerous proposition. I once sank into the space between the back and the seat cushions on a sofa (whilst asleep). I have to admit to feeling a certain amount of panic when I woke up groggy, enveloped and in pain.
Another time, I awoke to find my left arm completely paralyzed (it took an entire days for mobility to return). Needless to say, I'm something of an expert on the dangers of sleeping on sofas.
Also: sex on a sofa? Watch out for poorly placed tacks. I have an elbow scar from some strange interstitial metal point (later revealed to be tack-like in shape, and useless in function). Also: you can shove the seat cushions off via rhythmic fornication. You will suddenly discover your pristine arse coated in lost change, hairballs and other such refuse. Nothing is less sexy than counting bottom-change (but you can't resist)!
