What Is Zero Gravity?
Zero gravity describes a reclined position in which the knees sit above the heart, distributing body weight across the chair rather than through the spine.

Why chairs list multiple stages
Chairs commonly list two or three zero gravity stages. Each is simply a preset recline angle; more stages means more choice, not a different massage program.
Recline and wall clearance
Most chairs slide forward as they recline, so the stated wall clearance figure matters when planning placement. Check the reclined dimensions as well as the upright ones.
