Superday White 3 Drawer Mobile Locking File Cabinet - Under Desk

In this review the Superday White 3 Drawer Mobile Locking File Cabinet is examined for home office users and small workplaces who need compact, secure under-desk storage. The bottom line: it is a sturdy, space-saving vertical cabinet that secures three drawers with a single lock and fits neatly under most desks, making it a sensible choice for anyone who values organization and security without a large footprint. Assembly is minimal - wheels only - and the product arrives nearly fully assembled for quick setup.

Key Features

• Locking system: One keyed lock secures all three drawers and includes two keys so sensitive documents can be kept secure.
• Flexible file storage: Two adjustable hanging racks allow the file cabinet to accept A4, Letter, Legal and F4 sizes or be used without folders by dividing the bucket drawer into sections.
• Compact footprint: At about 14.9in W x 17.32in D x 23.8in H the cabinet fits under most desks or beside seating to save floor space.
• Durable construction: Constructed from 0.8 mm cold-rolled steel plate with ball-bearing glides for smooth drawer action and a rated support up to 330 lbs.
• Mobility and stability: Five 360-degree casters allow flexible placement and include locking capability to prevent unwanted movement.
• Organizational extras: A stationery tray is included and pull-out handles make it easier to access supplies and files quickly.

Who It's For

This cabinet is best for remote workers, small office teams or students who need a compact, lockable storage solution that slides under a desk. The steel construction and secure lock make it a good fit where document security and durability matter more than decorative finishes.

Those who need large-capacity vertical filing or drawer customization beyond three drawers and two hanging racks should look at taller, multi-drawer models. Buyers who prefer a wood finish or fully assembled caster bases out of the box might prefer other styles.
