The least expensive couch will be used. Salvation Army, Habitat or other local resale shop can be major sources for quality pieces from the time when things weren't all made in China. You can also get on the email list for local estate sales. Lots of quality can be found. Because your price point leaves few choices for new other than Chinese. Except IKEA. The Uppland has pocketed springs for the seat cushions, removable covers and a real 10 year warranty. Not your size and above your budget. Ikea has others to choose from. Draw and post your floorplan with measurements for more layout ideas.

Maybe we can come up with something really comfortable.
