This tray allows easy height, tilt, and swivel positioning of your keyboard. While it does offer both height and tilt adjustment these cannot be adjusted independent of each other, i.e. any adjustment requires resetting of both height and tilt. It includes a full-width leatherette-covered gel palm pad (with anti-microbial protection; 3M model WR340LE) and a 7.25" x 6.25" 3M Precise Optical Mousing Surface (MP200PS) that can be positioned to the left or right. Installation is done without tools in four easy steps, typically in less than 10 minutes. The sliding track is attached via an adhesive strip and the front is secured by hooking the front lip over the desk edge. Also, the keyboard tray is storable, but not fully under the desk (3.0" protrusion); and the tray itself is made of coated MDF (Medium Density Fiber) board.

The ClickIt-4ARM Adjustable Work Surface from SmartMotion Technology is a height and tilt adjustable work surface designed to support the forearms, upper arms, shoulders and neck while maintaining neutral positioning of the wrists. It tilts the entire work area, including keyboard and mouse, at an angle permitting the user to relax against their backrest while maintaining an open thigh-torso angle. Optional Left or Right forearm cushion accessories (shown in the image) are attached after installation, which allows the size of the user pocket to be determined by the pad placement. The 27" W x 20" deep work surface attaches to a heavy duty storable arm that permits partial storage of the work surface below the desk as well as providing the height and angle adjustment.
