  • Scapular Relief: The freedom of movement that this back allows eliminates awkward postures when reaching about the work station.
  • PressureCast Seat Foam: PressureCast foam cushions are used rather than cut foam to ensure seating comfort. Upholstery contours are retained during the life of the chair. Your chair lasts longer and feels better.
  • Intuitive QuickBack: QuickBack allows you to move the backrest through an unprecedented 6" range in 27 increments. Fingertip control positions the lumbar bolster exactly where you need it. The visible lever encourages adjustment.
