The Humanscale 500 Big Keyboard Tray design ensures that users type and mouse within their neutral reach zone, creating a safe, comfortable and sustainable work environment. The neutral zone in a standard office workspace is defined as the area where a user sits and works at a desk and can easily reach and interact with surrounding computer accessories, including a keyboard and mouse. Unlike older generation keyboard and mouse solutions, Humanscale keyboard trays are designed to ensure that nearly all users are able to work consistently within their Neutral Reach Zone, and thus maintain a low-risk posture. These boards keep everything on one worksurface rather than use a mousing platform; this keeps a mouse on the same tilt as a keyboard in use. If you prefer to set the mousing surface angle separately, any of the other Humanscale keyboard trays aside from the 400 keyboard tray platform offer this option.

The track mounts to the underside of your work surface and is what the mechanism slides forward and back on. Standard length on this mechanism is 21 5/8". If you do not have enough depth under your work surface to clear this, please see our Humanscale 500 & 550 Big Keyboard Tray - Design Your Own listing. Be sure to measure the depth under your desk (front to back) to confirm the track will fit; you need to have a track at least 1/2" shorter than the overall depth of your desk.
Choose no palm support or a 27'' long foam or gel filled palm support. Both palm supports are easy to clean and removable.
The Goldtouch Go! Travel Notebook and Tablet Stand will come in handy not only when you're traveling, but anytime you want to set your laptop or tablet in an ergonomic position.

This item also works well as a document holder, allowing you to input data without having to move your neck repeatedly from document to screen. The stand is lightweight and easily portable, yet strong enough to support laptops up to 17'' in length. Best of all, it's free!
