We've only had to replace one of these chairs in the past 15 years and that was because a dog ate it. They last forever. We've taken them everywhere. Backpacking, car camping, bleacher seating and boating. We did a 2 week dive trip in the Pacific and these were great a) they packed in our luggage, b) we were the only ones on the dive boat with back support as we were bouncing over the waves, c) even after getting soaked in salt water and gasoline, these baby's have lasted the test of time.
