Abstract
A lightweight chair capable of stacking for storage purposes is provided with collapsible, adjustable arms. The arms can be raised to a desired height where they automatically lock in place for use. The lock assembly can be manually released in order to adjust the height of the arms and coil springs prevent the arms from inadvertently collapsing against the seat frame and possibly injuring the hand of the user.
