What to Look for in a Good Ergonomic Chair
A good ergonomic chair should fit users
comfortably and support different working
positions

• Generous cushions and waterfall edge that
  encourage movement and circulation

• Synchronized tilt that mimics the bodys movement
  without straining the back. Good ergonomic tilts
  do not cause the front edge of the chair to rise
  during recline, ensuring proper circulation to
  the legs.
• Tilt tension that adjusts the recline resistance
  to the users preferred amount.

• Supportive foam that prevents bottoming out and
  pressure points.

• Soft edges on cushions that promote comfort in
  different seated positions. They also protect
  surrounding worksurfaces.
  
• The chair back that does not hinder arm movement
  while seated

• Tilt lock that supports the back in the upright
  position and variable position stop tailors the
  recline range.

• Adjustment knobs that are intuitive and easy to
  grip
  
• Simple, east-to-reach adjustments (for ADA
  accessibility.)

• Back height adjustment that controls the height
  of the entire back for lumbar and upper back
  support. (about 3-4 covers the full lumbar
  range.)

• Forward tilt that creates a forward incline of
  the seat and back with the ability to recline and
  lock in this mode. Forward tilt allows the chair
  to support the body in the position most people
  assume when typing.

• Arms that are recessed to allow the user to get
  close to the worksurface. Four-way adjustable
  arms include height, arm support width, fixed
  rotation and pad slide.
• Removable/retrofittable arms that adapt the chair
  to the users preferences and enable easy
  upgrades.
  

• Seat depth adjustment that changes the seat depth
  to accommodate different height users.

• Pneumatic seat height adjustment that includes
  optional cylinder sizes to accommodate different
  users.
