We purchased a set of Rollerblade office caster wheels.
We picked up a set of these office caster wheels that essentially have Rollerblade wheels on the bottom of them. Why you ask? Initially I wanted skateboard wheels for the bottom of my chair to maintain the aesthetic however those didn’t exist and Rollerblade wheels was the next best thing. Since Rollerblade wheels have a low Shore A rating of around 75A it meant that the polyurethane is soft and thus will not make any noise on hard wood floors. In less then a month of having these I ran into some problems!
