Universal Office Chair Wheels

These 3-inch replacement casters use a 10mm stem mount and fit 98% of standard office, gaming and stool chairs. They are sold new in a purple finish and are not compatible with IKEA chairs. The grip-ring stem measures 11 by 22mm for a secure push-in fit.

Heavy-Duty Steel Construction

Each set of five supports up to 650 lbs thanks to a high-grade steel bracket and internal components. High-quality polyurethane treads roll quietly on hardwood, tile, carpet and cement without scratching. Installation requires only pulling out the old wheels and pressing the new ones into place.

Upgrade From Worn Plastic Casters

The steel frame and polyurethane surface replace brittle plastic wheels that crack, mark floors or squeak. The jump is worth it when a chair sees daily use on mixed flooring and needs a higher load rating. Buyers who need IKEA-specific stems or a different stem diameter cannot use this model.

Questions about this item

What stem diameter does the 10 mm wheel use, and which chairs does it fit?

The grip-ring stem is 11 mm wide by 22 mm long, fitting 98 % of standard office, computer, gaming and stool chairs but not IKEA models.

What floor clearance and mounting space do the 3-inch wheels need?

Each wheel is 3 inches in diameter and mounts via a stem, so the chair base must accept an 11 mm stem and have room for the 3-inch wheel to swivel freely.

How are the casters installed, and what mistake should I avoid?

Pull the old casters straight out, then press the new stems in until the grip ring seats; do not twist or hammer the stem, or the ring will not lock.
