I have a red (salsa) Darcy Full Sofa Sleeper that I have used just for a few years and it is still in a very good condition. No stains or wear and the cushions are still firm. It is very spacious and comfortable with 3 seats. It also converts to a full size bed and has a mattress attached to it. I have attached two photos of my sofa so that you can see how it looks and it's condition. Here is a link to Ashley's website for this item. You can read the exact dimensions from there:
I am offering this very useful furniture (couch and the mattress inside it) for just $250. Please note that it's relatively large and heavy, so, if you are interested, it will need 2 people to take it from our apartment. We are at second floor, but have just 1 flight of stairs. We are moving to a different apartment and will not need this couch over there. The couch will be available for pickup from August 19th on any day. You can email me if you have any questions.
