We're expecting the delivery of a new sofa on Monday. After nearly fourteen years of service, our old couch has had it. The fabric is worn and even torn in some places. It's done its time. The new one is similar in style: an "L" shaped sectional. But I'm hopeful that it will be easier to maintain; most of the the fabric covers are removable and washable, and more of the cushions can be turned and repositioned for even wear.
