As another purchaser said, the screws did not fit -- in my case, it was the bottom rail under the seat. The screw-holes in the rail were too big for the screws to screw in tightly, so the chair looks pretty awful with a huge gap of visible screw between the legs and the rail. 

Also, unlike in the pictures, the screw heads are not recessed in the wood frame. Even if they had been, no screw covers matching the wood were provided anyway. So the chair's wood frame is dotted with large, blazing-silver visible screw heads. 

I'm definitely sorry I bought this.
