How do I know if a mobile pedestal will actually slide under my desk?

Standard pedestals stand 27–28 inches tall (casters included) and are 15–16 inches wide — designed to roll under a standard 29–30 inch desk with minimal clearance. Before ordering, measure the knee clearance height on your desk from the floor to the underside of the surface — you need at least 28 inches. Depth is typically 20–22 inches, which fits under most 24-inch desk returns. Always check the assembled height including casters in the spec sheet. FindOfficeFurniture.com lists all these dimensions — call 888-719-4960 to confirm fit.
