Went on in literally TWO minutes. Fit beautifully. Material is very soft, and chair doesn’t show through the fabric. Two issues unfortunately:  several strings hanging from bottom elastic. If they’re pulled the stitch pulls all across. Not sure what the effect would be. Also, a seam in back has a ‘free hanging’ 4” long, 2” wide piece of fabric sticking out!  Since it’s on the back I trimmed it very close and left it at that.
