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. Fixed surfaces are tested to meet ANSI/SOHO standards for safety and performance while the mechanical lift is rigorously tested to Bush Furniture quality standards. Backed by a 6-Year Warranty.
