Just noticed that one sofa looks smaller !! Is it standard size or is it a love seat size !! Here, a set can be sofa ( if regular size) and one chair !! But since yours are all covered in the same upholstery you could sell it as one set or divide it into two sets each having a sofa and chair !! You could ask $400 to $450 for the smaller one and a bit more for the larger set (say $500 to $550) or sell the whole thing for $800. to $850. !!
