Mine did exactly this.
I adopted a cat shortly after moving into a new house and he was very, very timid (still is, in fact, albeit less so) and about an hour after arriving he vanished into thin air. I spent the rest of the day and most of the rest of the night looking for him, petrified that my new house had some hole in the floorboards somewhere that I didn't know about and that had granted him his freedom, until I eventually saw a ginger tail poking out from within the armature of my sofabed.

He's too chunky to fit up there now, which is probably just as well.

Cats and folding furniture not a good combination
