Mobile filing cabinets are commonly made from medium‑density fiberboard (MDF), metal, or wood. These three material types appear most often across models and listings.
Mobility features vary but commonly include four or five casters (wheels), with many models offering lockable or removable casters. Some units also include anti‑tilt wheels or mechanisms to improve stability during movement.
Taller mobile cabinets often include anti‑tilt interlocking mechanisms that limit how many drawers can open at once, and some use anti‑tilt or anti‑tipping wheels to reduce the risk of tipping when a drawer is extended.
Most mobile filing cabinets require adult assembly. Some listings include tools, others do not, and a few models arrive mostly preassembled (commonly requiring only caster attachment).
Many mobile cabinets use full‑extension ball‑bearing slides (often steel) so drawers glide smoothly and open fully, providing easier access to files.
