How do a monitor arm and keyboard tray work together ergonomically?

A monitor arm and keyboard tray address ergonomics at two levels simultaneously: the monitor arm optimizes screen height (top of monitor at or slightly below eye level, screen at arm's length distance), while the keyboard tray optimizes hand/wrist position (keyboard at elbow height, slight negative tilt to keep wrists neutral). Together, they create a fully ergonomic workstation without compromising desk surface space. Without a keyboard tray, a monitor arm alone can improve screen position, but typing at desk height may still cause wrist elevation. Without a monitor arm, even a perfect keyboard position is undermined by poor screen height. The combination is the complete ergonomic solution. FindOfficeFurniture.com — 888-719-4960.
