Knoll Act I Keyboard Platform
The Knoll Act I Keyboard Platform is a slim and sturdy keyboard tray system sized to support both your keyboard and mouse on the same plane. The Act I gives you the choice of a durable phenolic plastic platform, or a 100 percent recycled and recyclable medium-density fiberboard option for the more environmentally conscious. For an even more compact model with a separate swiveling mouse platform, be sure to check out the Act II Keyboard Platform.

The Knoll Act I Keyboard Platform is available with several different mechanism options. All mechanisms feature spring-assisted knobless height adjustment, 360 degrees of pivot at the mechanism, and a black textured metal finish.
Short Easy Lift Arm
The Short Easy Lift Arm is ideal for shallower work surfaces. It features negative tilt adjustment from 0° to 15° and 4.26'' of variable height adjustment (1.06'' above the track to 3.20'' below).
Easy Lift Arm
For more height adjustment, the Easy Lift Arm features 7.04'' of variable height adjustment (2.83'' above the track to 4.21'' below). It also features negative tilt adjustment from 0° to 15°.
For maximum height adjustment, the Sit-Stand Arm gives you a full 11.57'' of variable height adjustment, and negative tilt from 0° to 15°. The Sit-Stand Arm features torsion spring-assisted variable height adjustment from 6.40'' above the track to 5.17'' below.
The platform on the Act I Keyboard Tray is available in a phenolic plastic, or a 100 percent recycled and recyclable medium density fiberboard (MDF).
All Knoll keyboard platform mechanisms come standard with 360 degrees of rotation at the mechanism. For even more flexibility and adjustment, you can add a second pivot point at the platform. This allows the platform to move independently from the arm, so that it can remain parallel to your desktop when the arm is rotated.
The Knoll Act I Keyboard Platform is available with five different track lengths to accommodate desktops of various depths. The minimum clearance required under your desktop is the length of the track plus 1/2''.
- 16'' track
- 17.75'' track
- 21.63'' track
- 22.63'' track
- 25'' track

Professor Ergo's Thoughts:
The Knoll Act I Keyboard Platform includes a detachable, comfortable foam-filled sliding wrist rest that is easy to remove and clean and can slide left to right to accommodate ambidextrous mousing. We recommend switching your mousing hand from left to right periodically to help combat or prevent pain and injury.
