Floating desk converts any desk or table into a Sit-to-Stand desk and allows you to use your computer in a sitting or standing position. Switching from sitting to standing, whenever you desire, is healthier, burns calories and will make you feel better. The elegant, contemporary desk riser allows one-touch movement to adjust your work space from a sitting to standing position. Monitor mount can be adjusted separately from the keyboard to get that perfect ergonomic position. The design is extremely sturdy and offers a stable worksurface. Large keyboard and mouse tray (26.4" x 9.1") give you a lot of flexibility and work space. The tray swings up and out of the way when you want to use your desk. Ergonomic floating desk can attach to the back, the side or the middle of your desk (through a grommet hole). Additional monitor arm/support bar and a steel accessory tray are sold separately..
