Chair Functions:

  • Pneumatic Seat Height Adjustment: Easy adjustment assures user's feet are flat on the floor and thighs are parallel to the floor, providing balanced support and better circulation to legs.
  • Tilt: For every inch you lean back, the front edge of the seat comes up an inch. Allows for a comfortable reclining motion that offers increased circulation and redistribution of pressure points.
  • Tilt Lock: Locks out tilt function when chair is in upright position.
  • Tilt Tension: Controls rate and ease with which chair reclines in relation to different body weights and strengths of users.
