Polar is a task chair that ensures ergonomic customization. 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 swivel base in die-cast aluminium is height-adjustable.
