Amazon sent the wrong item so I had to return it. Worse, it was too late to replace it so I had to use a camping chair at the beach.That would have been bad enough, but that chair got sand in the slider/closing mechanism was are impossible to close, had to leave itat the beach the second day. 3rd day had no chair until I bought a boring overpriced beach chair on the boardwalk.
