Features & details Flexible height adjustment: Adjust the desk height to a level that perfectly suits you with versatile height settings. Extra spacious work surface: Feel free to spread out with an extra large desktop for your computer monitor, paperwork, and desk accessories as well as an oversized U-shaped keyboard tray that accommodates flexible setup options like a 17-inch laptop or a full-sized keyboard and mouse. Quick-release, removable keyboard tray: Easy one-step attachment and release gives you the option to use the desk riser with or without the keyboard tray. Integrated air technology: Smart “x” structure and gas spring hovering system provide smooth and even support so transitioning from sitting to standing is safer and more reliable than other brands. Straight up and down movement: Our workstation rises and folds vertically, within its own footprint. There's no need to make spatial accommodations, as may be required in comparable products.
