Abstract
A chair is provided that is configurable to provide a substantially horizontal seating surface when the chair is disposed on an angled ground surface. The chair comprises a back frame having a pair of telescoping back legs including an upper back leg tube and a lower back leg tube slidingly disposed within the upper back leg tube. The chair additionally includes a pair of locking mechanisms comprising a locking key that includes a locking aperture through which the respective lower back leg tube extends. Each locking mechanism is structured and operable to selectively position the respective locking key in an engaged position that binds the lower back leg tube such that the lower back leg tube cannot slide into the upper back leg tube, and a disengaged position that allows the lower back leg tube to freely slide within the upper back leg tube.
