How much would you pay for this couch?

Im not sure how old it is, about 5 or 6 years i think. Its a dark green, really soft, and is like a normal 3 seater with an ottoman that you can make attatched to the couch by using the long cushion or using the small cushion and making it detached. it comes from a home with no smokers, but we do have cats and had a dog. The covers on the cushions come of and are clean. Its in great condition except there is a decorative plastic piping inside the cushion covers that came out on one of the cushions. Its been in storage for about a year and i need to sell it. How much should i ask?
