Pottery Barn Chair With Arms Cover Slipcover Cotton Beige Polyester Linen blend. I don’t have the right kind of arm chair to display it on. It needs a chair straight across the top. The back measures 25” top to bottom. 2” gusset. 6” drop in front . Chair seat width 17” . Arm length 13”. It appears to have been washed several times. Some pilling. A light pink spot on arm side. See picture.
