3 Drawer File Cabinet with Lock - Mobile Metal Filing Cabinet

In this review the Aobabo 3 drawer file cabinet is evaluated as a compact, sturdy solution for home offices and small businesses that need secure, mobile document storage. The single biggest reason to buy is its combination of heavy-gauge steel construction and a built-in lock, which together provide reliable protection for letter and legal files while fitting neatly under a desk. The unit arrives fully assembled except for attaching the casters, so it is ready for use quickly and feels solid right out of the box.

Key Features

• Fully assembled: The cabinet ships with all drawers preassembled so setup is limited to attaching the casters, saving time and hassle.
• Large storage capacity: Each of the three drawers accepts a substantial number of hanging folders, helping organize both letter and legal size documents.
• Security lock: An integrated lock secures the top drawer and protects confidential paperwork when the cabinet is not in use.
• Durable steel build: Constructed from high-quality metal, the cabinet resists deformation and provides long-term durability in busy office environments.
• Mobile design with brakes: Five included casters, two with braking function and a center caster to reduce tipping, add stable mobility for repositioning the unit.

Who It's For

This cabinet is ideal for small business owners, remote workers, and home office users who need a compact, lockable storage solution that fits under a desk and moves when required. It suits those who store a mix of letter and legal documents and want a metal unit that feels robust.

It may be less suitable for buyers who need large-scale archival shelving or a fully assembled unit with no caster installation at all, since the wheels require simple attachment. Customers seeking soft-close drawers or decorative furniture finishes should look elsewhere.

Pros & Cons
