Chair Adjustments for Ergonomics
 copyright 2007, DISPATCH Monthly Magazine Seat height adjustment--The best chairs use a compressed gas lift mechanism to provide continuous and easy adjustment of the seat height from the floor. One chair will usually not provide enough height adjustment for everyone in your comm center--you may need a chair sized for smaller and larger-frame persons. Seat glide--The seat cushion should move forward and backward to accommodate different anatomies. Arm height adjustment--The arms should adjust up and down to accommodate different arm lengths. Arm contoured--The contour of the arm cushions should mold to the arm to relieve pressure. Like other parts of the chair, this may be a compromise for smaller and larger persons. Back & seat tilt--The seat and back should be tiltable as a unit, both to encourage proper adjustment of other chair parts, and for overall comfort when seated. Seat back height--The seat back should raise and lower to fit the person's back. Back lumbar support--The lower portion of the back should allow some adjustment for the lower hip/spine area of the person. Arm width adjustment--The arms of the chair should adjust in and out, to accommodate smaller and larger persons, and their preference of arm support. Non-tip base--More than just ergonomics, safety dictates that the chair have a sturdy and tilt-resistant base. Chairs with five wheels are most common now--avoid older chairs with just three spokes. |
