EFG task chair is as comfortable as it looks. The design of this chair is ergonomic and contours the proportions of the user providing excellent comfort and support. This provides both durable support and a desirable level of flex to achieve a continuous and comfortable ride. Choosing Refurbished Chairs: Our chairs are fully tested, and we love bringing these back to life with it being newly upholstered. Parts remain: The arms, castors and base may show signs of wear and tear. This will not affect the functionality of the chair.
