The Bush Business Furniture Series C 3 Position Sit to Stand L Shaped Desk with Mobile File Cabinet offers an ergonomic workspace solution for the health-conscious professional. A 72W x 30D Office Desk and 42W x 24D 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-n-Lock system allows the desktop to lock into place at standing heights of 36, 39 and 42 inches from the floor and easily returns 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\/BIFMA standards for safety and performance, and the mechanical lift system is rigorously tested to meet Bush Business Furniture's own quality standards. This office furniture set comes in your choice of stylish Mocha Cherry or Hansen Cherry with Graphite Gray finishes and is backed by a 10 year manufacturer's warranty. American made with U.S. and imported parts.
