I have an old, comfortable chair that I had been using.  My dog likes to use the chair as well.  I had thrown a blanket over the chair as a temporary measure thinking I would probably get rid of the chair soon.  However, I've decided to keep the chair and wanted a better cover for it.  It's an odd size chair with wide square arms.  This stretch cover works great and looks much better than the old blanket!.  Took a few minutes to put on, but once I figured it out, it was simple.
