I couldn't put the chair together. Wayfair customer service was fabulous. The back had a metal slide to attach; the base had a large plastic square. If the square was a protective piece, the picture instructions didn't show it. I thought I remembered a video where the back slid over such a square. I gently tried to pull the plastic square off, but it didn't move and I didn't want to force it. At any rate the replacement chair was identical, so I sent them both back. FedEx delivered them to my door and is scheduled to pick up the boxes today. I sat on the base a couple times, and it seemed stiff and hard. I gave 3 stars. It's possible I just didn't pull off a shipping cover, but I didn't get it assembled. It seemed sturdy. The sides slid on easily and seemed secure. I didn't attach the remote.
