Foldable - lightweight and folding design for easy transportation and storage. Material used is weather resistant and easy to clean. Adjustable - easy-to-use twist knobs effectively locks to chair in any position.
For the money, this is a good deal. Construction is decent and the double 'stitching' that hold the eyelets to the frame is a nice feature. If I get 3 seasons out of these chairs, it would be a good thing. In my case they will be kept out of direct sunlight as much as possible since that is what causes the most breakdown in the fabric. I'm on the East coast and shipping from Cali was super fast (way to go FedEx).
