Unique Boss Task Features:

  • Massive Construction: Everything about the Boss Task Series is designed for tough use. The massive backrest upright is of a heat-treated alloy that will never bend or break.
  • 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.
  • Exceptional Lumbar Bolster: The pronounced lumbar bolster, the thoracic reliefs and the gentle seat contours provide support along the entire torso for all day comfort.
  • Easy Ratchet Back: No handwheels to twist! This ratchet back is one of the simplest and ergonomically friendly ways to adjust lumbar height. Click it into eight positions over a generous 4" range.
  • Seamless, Intensive-Use Base: Safety is ensured with this specially engineered, five star base. Cast as a single piece, there are no welds to break.

Boss Task, full-scale with the advanced ergonomics you expect from Sitmatic.
