These chairs are dangerously defective. They are not safe. The back legs are attached to the body of the chair only by then metal staples that easily sheer off or pull away from the rest of the chair. When you assemble it, you are given sturdy bolts that make you think it will be a sturdy chair, but actually you're just attaching the leg to a piece of wood that's been stapled in place. We bought 4 chairs a month ago, one has already had a leg come off, and two others are beginning to fail. These chairs are dangerous and should not be used by anyone!
