Polar is a task chair that ensures maximum customization in terms of ergonomics. The backrest has a nylon frame with a breathable, flexible polyester mesh for a sense of transparency. The injected-moulded polypropylene support at the lumbar area may be covered in the same fabric as the seat. The seat, in polyurethane foam, can move via a special mechanism that allows its depth to be adjusted. The chair guarantees excellent comfort thanks to its weight-activated, synchro-tilt mechanism that is able to regulate the degree of tilting autonomously according to the user’s body weight. The armrests can be adjusted in height, depth and width, and can be orientated to suit the user’s needs. The swivel base in die-cast aluminium is height-adjustable.
