We don't want to redecorate/get new carpet as in good condition and we have other priorities. Sofa has to be leather. Ideally, I would like a grey sofa but don't think that it will go with the walls and carpet. So I am thinking about getting a dark brown sofa (I know that they're not popular on here) with mustard, lime or orange accessories - I don't want teal as we already have that in another room.
Many thanks!
