@spendius,
												
That's exactly what my sofa needs, Spendy. You're on to something there.
Don't fancy a secondhand one, though.  You just never know, do you.  If there was more space in the TV room, no problemo, I could get a really sinful one.
Actually when I've got serious TV to watch I can push my comfy chair across.
