Tired of your office chair scratching up your nice floors or making that awful rolling noise? Swap out those old wheels for these quiet rubber casters! This set of five has a standard M10 screw thread (about 10mm), so they fit most office and desk chairs. The wheels are 1.5 inches in diameter and made from a soft, synthetic rubber that glides smoothly over hardwood, laminate, tile, and other hard surfaces without leaving marks or making much sound. They swivel 360 degrees for easy maneuvering, and each caster can handle up to 66 lbs, so the whole set supports around 330 lbs—plenty for any office chair. Installation is a breeze: just unscrew your old casters and screw these in. They're also great for other furniture like plant stands, small tables, or shop stools. A simple upgrade that protects your floors and makes rolling around much quieter.
