These are the height-adjustable, articulating platforms that allow computer users to quickly switch from a seated to a standing work position. The monitor stand raises a laptop or flat screen monitor up to 24" and rotates 360 degrees in 15 degree increments to place it at eye level. The keyboard tray raises a keyboard up to 18", rotates 180 degrees, and can be angled downward—an ergonomically correct typing position that helps prevent wrist fatigue. Each component has push-button joints that easily rotate for fast, easy adjustment and lock securely in place. A 7" x 7" adjustable mouse pad attaches to either side of the keyboard tray to keep the mouse at the optimal height and angle. Made from commercial grade aluminum that naturally dissipates heat from laptops. Supports up to 13 lbs. Black. Monitor stand: 2"-24" H x 18" W x 11" D; keyboard platform: 2"-18" H x 18" W x 11" D.
