Abstract
Abstract The lounge chair is not only pivotal from an upright position into a reclined position via the use of telescoping arms of the arm frame but also collapsible from the upright position into a folded position via hinges at the rear of the chair. The chair can be easily transported and stored in the collapsed condition by either laying flat or by standing upright.
