Abstract
A folding chair is disclosed which can be used on sloping or uneven terrain. Individually adjustable legs and leveling feet provide flexibility of use, comfort, and stability where ordinary folding chairs cannot be used. In an alternative embodiment, ball and socket leveling feet are used to level the feet and distribute the leg loads. Grooved resilient pads on the bottom of the feet prevent slippage on hard surfaces such as rock or concrete. Closable storage compartments are provided in the arms for storage of small items,
