🥇【Universal Size】This gaming chair base replacement is compatible with most chairs on the market, such as Herman Miller office chairs, gaming chairs, desk chairs, and executive chairs. Fits casters with 7/16″ x 7/8″ (11 mm x 22 mm) stems and gas cylinders with a 2″ (5 cm) diameter.
🥇【Durable and Sturdy Materials】This heavy-duty base is made of chrome-plated metal with a matte finish. The solid tubular iron structure is reinforced with screws, providing enhanced load-bearing capacity and safety. It can support up to 2500 lbs.
