The Optum 60x30 Desk features a unique two-sided top that lets you choose from walnut or espresso with a 3mm gray edge band when assembling. The silver-finished steel base is adjustable in width so it could be used with a smaller top if you ever decide to downsize. The commercial-grade, ANSI-BIFMA approved work surface is water, scratch and stain-resistant. The base includes two full size O-legs and one short O-leg that can be used on top of a cabinet to create L or U-shaped configurations. Leveling floor glides help keep it stable on uneven floors. Other sizes and colors are also available. NOTE: The top will attach to the base with screws, so it's no longer reversible after it's been assembled.
