Query: Nice chair but not very sturdy

Very nice chair. Comfortable, easy to assemble, and light weight. However, chair collapsed first time on boat. We weren't 5 miles from the dock when we hit a wave and the chair collapsed. A total loss. Probably should not sit in chair while the boat is underway. Took chair to dumpster on way home. I would recommend this chair for the deck or dock, maybe in calm water. I would not call this an offshore chair. We were definitely inshore when it crumbled. Just glad no one was hurt.
