This is a Marks & Spencer sofabed from 1998-ish. It has had heavy use in our lives, but is still completely functional (both the sofa and the bed function). There is some worn fabric on some edges at the back, thanks to cats scratching.
The bed size is not a convensional size, so it needs an unfitted sheet, ideally. Comes with armrest covers and a matress protector. It comes with a matching wheeled ottoman/footstool - preferably I would like both to go, but sofa only collection is also fine.
Approximately:
190cm across
75cm tall
95cm deep.
