SPACELEAD Office Chair Caster Wheels Universal Size Stem Polyurethane Rollerblade Style No Tools Required Replacement

These office chair caster wheels are replacement wheels for upgrading a rolling desk chair. The rollerblade-style wheels are encased in soft polyurethane to help prevent scratches or marks on hardwood, carpet, tile, laminate, and other floor surfaces. Installation requires no tools and takes less than 30 seconds by pulling out the old caster wheels and popping these in. The universal size stem fits almost every office chair on the market, and the product carries a lifetime warranty that never expires. The original design was invented in 2016, and over 1,000,000 sets have been sold by a small American family business.
