An ultra low-profile workstation that adjusts between sitting and standing working heights: With a storage depth of just 10,2 cm ( 4 inch ) (10.2 cm), it is the perfect solution for space-constrained high-traffic areas and hallways. Move the entire system-monitor, keyboard and mouse-in a single motion. It includes an auto-retracting tray that returns the keyboard to the storage position when not in use.
