5 Black 2-inch Office Chair Caster Cups

These five black 2-inch office chair caster cups/furniture wheel stops feature felt bottoms for a non-slip grip and to protect hardwood floors. They are suitable for cribs or office chairs with wheels. Their core function is shock absorption: when a crib stops after being pushed, or an office chair suddenly leans back, the felt bottom of the wheel stop, combined with the elastic structure of the cup, effectively absorbs impact and vibration, preventing the furniture from continuing to slide due to inertia or making loud noises. Especially for cribs, the shock absorption function prevents bumps that might wake the baby. The black color is stain-resistant, and the thickened cup body is less prone to cracking. The smooth felt bottom won’t damage the floor. Placing the wheels in the cups keeps the furniture firmly in place, dissipating vibrations and preventing wheel marks from appearing on the floor.
