Caster Cups

Caster cups keep furniture with wheels or posts from marking your floors and drifting out of place. This furniture hardware spreads load across a wider footprint, reduces dents on hardwood, stops casters from cutting into vinyl, and prevents carpet divots. They also quiet movement, add traction on slick tile, and help lock beds, sofas, pianos, and chairs where you want them.

Options range from grip-heavy rubber and silicone to clear polyurethane and felt-lined designs that are gentle on finished wood. Deep-dish cups cradle round furniture casters, while low-profile pads suit square legs or glides. You’ll find round and square profiles, multiple diameters, and heavy-duty piano caster cups for grand instruments and oversized appliances.

To choose the right cup, measure the wheel or leg you’re supporting and match it to the internal diameter. Check load capacity per cup, then multiply by the number you’ll use under the piece. Match material to your surface: soft rubber for tile and laminate, non-marking polyurethane for hardwood, felt-bottom cups for delicate finishes, and spiked bases for carpeting. Look for anti-slip textures, recessed wells that prevent rolling, and UV- or moisture-resistant compounds for sunny rooms or damp basements.

Installation is tool-free: clean the floor, place the cups, then lower each caster into the recess. For tall items, slide cups in one at a time to maintain balance. Adhesive-backed styles help on uneven floors, and stacking shims can add a touch of leveling.

Maintain performance by wiping dust from cup bottoms, checking for compression wear, and replacing any that harden or crack. Compared to sliders, caster cups prioritize grip and floor protection over easy movement. If you need stationary stability, scratch prevention, and noise reduction for beds, dressers, file cabinets, and pianos, the right caster cups deliver long-lasting floor protection and reliable furniture control day after day.
