The l-shape executive/standing desk with a mobile file cabinet offers an ergonomic workspace solution for the health-conscious professional. An office desk and sit-to-stand return attach to form a space-saving corner desk design and both feature scratch-resistant 1-inch thick thermally fused laminate surfaces with wire management. As a quality alternative to desktop risers, the innovative sit-to-stand return offers all the health benefits of a standing desk with the versatility of more expensive electric height-adjustable options. The mechanical lift and lock system allows the desktop to lock into place at standing heights of 37, 40, and 43" from the floor and easily return to a seated position. The 3-drawer filing cabinet's bottom drawer opens on smooth full-extension ball-bearing slides and holds legal, letter, and A4 size files while a built-in lock protects sensitive documents. The l desk and mobile file cabinet have finished backs that allow them to look great in a private office or open workspace. Fixed desks and storage are tested to meet ANSI/bitmap standards for safety and performance.
