Designed to retrofit to work surfaces up to 3” thick. Height-adjustable so you can enjoy the ergonomic benefits of a standing desk without refurnishing. Manually adjustable, this workstation is easy to operate and provides personalized ergonomic positioning for right- and left-handed users. Made from steel and aluminum with a powder coat finish, the workstation is durable and aesthetically appealing. Supporting up to 11 lbs., the monitor arm is VESA compatible, and attaches by C-clamp to the back edge of your desk or table. The arm also provides cable management for an organized, cordless desktop. Monitor and keyboard tray height are individually adjustable to accommodate user preference, and the workstation also offers monitor tilt adjustment to help alleviate strain on the eyes. All height adjustments are made manually without the use of knobs or levers, and the entire assembly swivels left and right for desktop access. The adjustable keyboard tray is extendible/retractable for custom positioning, and is rubber-coated and texturized to help hold the keyboard securely in place. In addition to its ergonomic benefits, this sit-stand workstation occupies a relatively small surface area compared to similar products.
