Product description

The Orthopaedica 90 Series Synchronised Mechanism Task Chair, from Torasen, is a no-arms office chair built around a synchronised mechanism with back locking function, so the seat and height-adjustable ratchet back move together and can be locked in place once you've found your position. It runs on 60mm hard wheel castors and adjusts from 1070mm to 1260mm overall height, with a 670mm width, 640mm depth, 510mm seat width, 480mm seat depth and a seat height that adjusts from 460mm to 570mm. For anyone who needs more from their seating, it can be specified with optional extras including 50mm seat depth adjustment, inflatable lumbar support, inflatable thoracic support, an AirTech seat, a coccyx cut-out, or soft wheel castors for hard floors. Shop direct today from DBI Furniture Solutions for ergonomic support built into every adjustment.
