If you have a couch that looks as though it has seen better days, yet it is still sturdy and comfortable, try using a couch cover instead of purchasing a new couch. A fitted cover can be purchased for around $100, which is cheaper than buying a new couch. If that seems out of your reach, try a quilt or blanket to cover the seating area. Measure the size of the seating area and use a blanket that matches. You might even be able to cover the back area as well.
