1 Sacral support adjusts in height, depth, and angle- critical for stabilizing the pelvis in its proper neutral position. Also stabilizes the lumbar spine and sacroiliac joints.
2 Lower thoracic support adjusts in height and depth- critical for proper alignment of the trunk, shoulder girdle, head, and neck. Elevates and stabilizes the rib cage, elongates the spine, prevents slumped posture, and promotes proper diaphragmatic breathing.
3 No support to upper back and shoulder blades-
detrimental to healthy sitting posture by pushing the shoulders and head forward, and inhibiting diaphragmatic breathing.
4 No lumbar support - detrimental to healthy sitting posture by distorting the proper upright relationship of the rib cage and pelvis, with the upper trunk being displaced behind the hips. Sitting with lumbar support will relax the lower abdominal muscles, shorten and compress the spine, and increase stress to the neck and upper back.
5 No support to the posterior buttocks- detrimental to healthy sitting posture by pushing the buttocks forward on the seat, thereby preventing proper pelvic and spinal stabilization.
6 Armrests adjust in height & width- are positioned on chair to facilitate use of backrest and to prevent collapsing body weight forward on the armrests.
7 Firm, contoured seat- facilitates use of backrest, stabilizes the pelvis, and prevents weight bearing on the tail bone.
8 Pneumatic, adjustable seat height- critical for proper sitting stability with feet firmly on the floor.
9 Scuff Pads - Provide protection from scratching base & furniture. (Not available on 2007 chair base)
10 Casters- Available for carpets (hard casters) or hard floors (soft casters).
