Chairs: Proper Adjustability and Quick Tips
  1. Backrest: Should follow the natural curvature of the spinal column and provide ample support to the lumbar and thoracic regions of the back.
    1. a. Height adjustability, tilt (approximately 15 degrees from a vertical position) with the ability to lock in place or allow movement with a certain amount of resistance
  2. Seat: Padded and comfortable for the user; it is recommended that the chair has the ability to adjust the height and seat pan depth (i.e. forward and backward), allowing for the use of the entire backrest. Correct size seat pan depth includes approximately one inch on each side of the seat (from the body to the edge of the seat)
  3. Armrests: If provided, should be soft; allow your shoulders to relax and your elbows to stay close to your body. The arm rests should not be utilized as a support throughout the day when using the chair.
  4. Base: A chair should have a study base with five legs and casters that allow easy movement along the floor.
