Abstract
A zero gravity chair generally holds an occupant in a position where the angle between the legs and the torso may be greater than 90 degrees. Typically, the legs may also be elevated such that the legs are even with or above a user's heart. The disclosed zero gravity chair, in some embodiments, enables the backrest portion to pivot relative to the seat portion allowing the user to adjust an angle between the seat portion and the backrest portion. The disclosed zero gravity chair further enables both the backrest and the seat portions to pivot as a unit independent of the angle adjustment. In certain embodiments, the chair also rotates 360 degrees about a vertical axis.
