Rosie, I think if it were me, I'd follow kidkruger's advice - he seems to have hit the nail on the head: >>>>Get rid of it snd say you lost it. Get rid of it and say you we're 'burgled'. Get rid of it then before end of tenancy replace it with a sofa 2nd hand from EDF of equal quality (you'll likely be able to get better quality) quite cheaply. You can say something like a friend weed on it - something which writes-off the landlord wanting to keep it but shows you've resolved/improved his sofa situation.
