CAN OTHER CHAIRS DUPLICATE ZACKBACK’s UNIQUE SITTING POSTURE?
No. Due to the precise sacral and lower thoracic support adjustments in height, depth, and angle; the firmness of the back supports; the angle of the backrest frame; and the seat slope, shape, and special fabric – it is not possible to duplicate ZACKBACK’s optimal healthy sitting posture in other chairs. It is just as critical to the success of the ZACKBACK concept and chair to avoid support in areas that are almost always supported in other chairs. ZACKBACK’s critical areas of no support include the posterior buttocks, the lumbar spine, and the scapulae (shoulder blades). Supporting these areas distorts one’s sitting posture and results in a relaxation of critical trunk muscles and an inhibition of proper diaphragmatic breathing.
