Ergonomics – The Right Chair

Are you using the right chair for you at your worksite? A properly designed and adjustable chair is critical to a workstation.

  • The chair should be fully adjustable— height, armrests, lumbar support, and backrest.
  • The height and tilt of the backrest should be adjustable. The tilt adjustment should be forward and backward.
  • The chair should be sized correctly for the user.
  • If a new chair is to be purchased, it is recommended the chair be loaned for a 3 – 5 day period so that the user can allow his/her body to adjust to the chair.
  • The front edge of the seat on the chair should not be in contact with the user’s legs while sitting. This will help to minimize poor leg circulation and allow the user to sit back against the backrest.
  • The chair should be supported by a five-leg base for stability, and glide easily along the floor surface.
  • Become familiar with the operations of your chair. Many people do not know how to use all of the adjustments on their chair.


The user must be positioned properly in the chair.

  1. Feet flat on the floor.
  2. Knees and hips at a 90º angle.
  3. Buttocks back in the chair.
  4. Lower back should be against the backrest and be supported in the lumbar region of the back.
