The POLAR 3770 is an ergonomic office chair designed for optimal customization and comfort. Its nylon-framed backrest features a breathable polyester mesh, providing flexibility and a sense of transparency. The lumbar area is supported by an injected-moulded polypropylene structure, which can be upholstered in the same fabric as the polyurethane foam seat. This seat is equipped with a mechanism that allows for depth adjustment, enhancing user comfort. The chair's weight-activated synchro-tilt mechanism autonomously adjusts the tilt according to the user's body weight. A height-adjustable swivel base made from die-cast aluminium completes this modern office solution, making it suitable for corporate offices, coworking spaces, and educational institutions seeking collaborative workspace furniture.
