Upgrade your personal workspace with the ergonomic 3 Position Sit to Stand L Shaped Desk. 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 built-in mechanical Lift-n-Lock system allows the desktop to lock into place at standing heights of 37, 40, and 43 inches and easily return to a seated position. The Return has a counter-balanced design for stability and supports up to 20 pounds when elevated. The 72W x 24D Office Desk includes a file drawer that opens on full-extension ball-bearing slides for easy access to legal and letter size documents in addition to a box drawer for supplies and utensils. Both the Desk and Return feature finished backsides that allow the L Desk to look great no matter where it's positioned in the room. Wire management grommets are included on both surfaces to keep cords and cables secure and out of sight. Available with contemporary metal hardware and tapered leg accents, the height-adjustable corner desk has an appealing look that works with virtually any decor. Fixed surfaces are tested to meet ANSI/SOHO standards for safety and performance while the mechanical lift system is rigorously tested to our own quality standards.
