    FAQs

    The V1 is a tall, fully adjustable chair sized for users 150–190 cm. The seat adjusts from 47.5 to 57 cm high and 44.5 to 49.5 cm deep, is 53 cm wide, and the chair stands 116–137 cm tall overall, so it suits taller users and anyone who wants to fine-tune every part of the chair.
    The V1 is rated to a maximum user weight of 136 kg.
    Seat height (47.5–57 cm), seat depth (44.5–49.5 cm), the 3D headrest (height, angle and depth), the 4D armrests (height, depth, width and pivot, with 360° rotating pads), the cushioned lumbar support (height and depth), backrest recline from 90° to 140° with adjustable tension and multiple lock positions, 360° swivel and, on 'with Leg rest' options, the fold-away footrest.
    It is your choice. The V1 is sold in Black and Grey either with or without the leg rest; the 'with Leg rest' options add a padded footrest that slides out from under the seat for reclined breaks and folds away when you are working.
