Abstract
A height adjustable chair has an upper portion that moves relative to a lower portion. Push-off arm rests are provided so that a person need not leave the chair to adjust the seat height upwardly. A seated person can transfer their body weight to the push-off arm rests supported directly by the stationary lower portion while the seat is being adjusted upwardly.
