Final Thoughts: Why You Need a Standing Desk with Drawers
Some of the very standing gaming desk may not even have crossbars. Of those that do, models that have “T-leg” frames, meaning the lifting columns are located in the center between the front and back edges of the desk, will have the least amount of free draft. Those with cantilevered, or “C-leg” frames will have deeper drafts, but even these can sometimes be as shallow as only 11″ deep. To measure the free draft under your desktop, simply measure the distance between the user edge of your desk and the crossbar.

The Fezibo standing computer desk does everything a keyboard tray needs to, does it well, and comes in at a surprisingly low street price. 15º of negative tilt is an industry standard for adjustable trays, and while the 5º that the Stowaway adds to that doesn’t sound like much, some users will find the extra tilt essential to finding a comfortable, ergonomic position especially when using a treadmill desk. A wide range of height adjustment is complemented by removable gel/foam wrist pads (perfect for accommodating ergonomic keyboards).
