Most models use four swivel or universal casters for smooth movement. Many list locking brakes or lockable wheels (often two locks) so the cart can be secured in place.
Weight limits vary by model. Some three-tier carts list about 22 lb per shelf; drawer-style carts cite lower drawer limits (examples: large drawers ~5.5 lb, small drawers ~3 lb). One model also cited a 22 lb tabletop limit.
Reviewers commonly report smooth-rolling wheels and good maneuverability. Many listings and reviews also reference lockable wheels or casters for keeping the cart stable when needed.
Example dimensions include interior drawers about 13.5" x 10" x 2" for a 10-drawer unit, and for a 12-drawer option large drawers at about 14.5" x 11.5" x 5" with small drawers about 14.5" x 11.5" x 2.5".
Space-saving designs include V-shaped tiered shelves and compact vertical three-tier footprints; listings call out these V-shaped shelves and compact footprints as fitting narrow corners or tight rooms.
