Open Up™ High-back

Designed by Mathias Seiler for Sedus Design Group

An innovation in seating, the trim profile in elegant mesh expands your comfort zone with advanced features in ergonomic design

High-Back works with you — the articulating head-rest is adjustable in both height and pitch

Eases movement, minimizes back strain and supports bodies at rest or in motion; the synchronized tilt with accessible side tension control and the generous recline with multiple tilt-lock positions provide easy, natural adjustments and extraordinary comfort

Dorsokinetic backrest suspension naturally follows the movements of the upper body

Height-adjustable lumbar cushion enhances back support

4° forward tilt eliminates strain during intensive keyboarding

Optional techno-gel or leather-covered armpads available

Five-year multi-shift warranty
