I`m very happy with this slipcover. I think it`s the best thing next to having the chair re-upholstered professionally. The 4 pieces stretch 4 ways due to having a spandex content in the material.  The edges with elastic on them never slip, and having loops on the bottom holding the larger pieces secure to the chair legs is pure genius. These covers aren`t your mother or grandmother`s slipcovers, they are far superior. You won`t be sorry you ordered them.
