Tired of your office chair scratching up your hardwood floors or making loud rolling noises? Swap out those old plastic casters for these heavy-duty rubber wheels. The set includes five casters with polyurethane treads that protect floors from scratches and dents. The stem size is 11mm x 22mm (standard for most office chairs), and they’re made from stainless steel and high-carbon steel for durability. Each caster supports up to 99 lbs, so the whole set can handle nearly 500 lbs. They roll quietly and smoothly on hardwood, tile, laminate, and even low-pile carpet. Installation is a breeze — just pop out your old wheels and push these in. No tools needed. If you work from home or spend hours at your desk, these upgraded wheels make moving around quieter, easier, and much kinder to your floors. A small change that makes a big difference.
