Can I add filing storage under a corner desk return?

Yes — a mobile pedestal or under-desk file cabinet slides under most 24"-deep returns with standard 28"–29" clearance height. Box/box/file pedestals on casters are the most flexible option since they roll out when you need files and tuck back under when not in use. Make sure to measure the clearance under your specific desk model before ordering a pedestal. FindOfficeFurniture.com has matching pedestals for most corner desk configurations — call 888-719-4960.
