The chair is well built and sturdy. Of course no written instructions but it's easy to open and the adjustment from sitting to reclining is not hard to figure out. Just move the back supports while sitting up (no weight on the back) and they slide either way quickly and easily. Good design and light weight, I prefer this to the heavy cumbersome zero-gravity chair that I've been using when camping. Folds up quickly and fits back into the carrier for compact storing.
