Purchased 4 of these and I am very disappointed in the overall quality!  Not worth $275/piece.  They do not swivel 180 degrees (360 instead), loose threads on the fabric, the screws they give to attach are barely long enough and 2 of them have already stripped... I have contacted my account manager in hopes that they will be able to do something for us but haven't heard back yet.  Overall I have been happy with Wayfair and hope they come through on this.
