Enable an ergonomic, healthy workspace using the white Mount-It! Single Motor Electric Standing Desk Base. This frame provides 28.3 to 46.5' of height adjustment and a weight capacity of 154 lb for both a separately purchased tabletop and the computer setup on top of that. The legs expand from the middle between 35.4 and 53.1' to accommodate different sizes of tabletops. The touch panel which attaches to your tabletop allows you to save three heights you can return to later for consistent use.
