Compatibility: fits under legs, corners, and bases of sofas, dining tables, chairs, cabinets, bookshelves and appliances where small height adjustments are needed. Simple to use: slide a shim under the low corner, test stability, then add or remove shims until the furniture sits level. No tools required. Practical use scenarios Dining table that wobbles on an uneven floor: insert one or more shims at the low leg, stacking as needed until the table is stable for safe, spill meals. Recliner or sofa with a rocking corner: place shims under the short leg to eliminate rocking and reduce stress on frame joints.
