The elegant office swivel chair AC 5 Work is equipped with a range of sophisticated functions that not only guarantee healthy seating comfort, but are also discreetly out of sight. This clean look enhances the graceful lines of AC 5 Work, whose distinctive design and uncompromising functionality make it a perfect seating option for well-appointed offices. The sophisticated structure of the AC 5 Work backrest with three different zones – lumbar zone, sink-in zone and shoulder zone – provides optimum support for the neck and prevents muscle tension. Further ergonomic features of AC 5 Work include the FlowMotion mechanism with synchronized forward tilt and seat depth adjustment, as well as the innovative FreeFloat armrests.

– Seat mechanism: FlowMotion mechanism with synchronized forward tilt (can be disengaged) and with seat depth adjustment. Seat mechanism powder-coated in basic dark.

– Backrest and seat: self-supporting backrest structure with horizontally stitched padding. Backrest mount in polished die-cast aluminum. Optional height-adjustable lumbar cushion. Seat cushion in polyurethane foam. Cover in fabric or leather.

– Armrests: optionally equipped with fixed, polished die-cast aluminum ring armrests for conference areas (optional leather covers matched to the leather upholstery; for chairs with fabric covers, the leather armrest covers are in the color nero) or with FreeFloat armrests with polyurethane pads in basic dark.

– Base: five-star polyamide base in basic dark or polished die-cast aluminum base with double casters (2.3″) in basic dark.
