Unique Beta² Features:

  • 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.
  • Lumbar Support: The scientifically engineered shape hugs and supports the back from lumbar to thorax.
  • 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.
  • Cast Aluminum Base: The cast aluminum base is stronger and more durable than comparable plastic bases and is easier to recycle.

Beta², versatility and value in professional quality ergonomic seating.
