Uncaged Ergonomics CHANGEdesk, Black (CDMb)

1. Taller height range: CHANGEdesk elevates monitors to 5 settings between 4-21.5" above your desk. This is much higher than other standing desks and ensures that your monitor will be properly positioned at eye-level to prevent hunching. 2. Adjustable keyboard tray: the keyboard tray height isn't fixed, but rather moves in the proper proportion to your monitor. As you raise your monitor higher, the distance between your monitor and keyboard increases. This helps ensure that your keyboard is always positioned at the proper height (about elbow-height). 3. Super quick adjustment: effortlessly move between sitting & standing ... it takes just seconds! 4. Simple, effective, versatile design: ships assembled. Requires no installation.
