Alpha Features:

  • PressureCast 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.
  • Ergonomic Foot Perch: Textured ridges on the end or our bases provide excellent traction when the base is used as a foot perch. Our safe cast aluminum bases are shatter-proof and will withstand decades of use and abuse.

Alpha, a full family of highly refined seating, designed to exceed corporation's most rigorous standards.
