A very nice Faultless-Doerner Aluminum Frame rolling swivel stool. From the style it looks to have been made in the 1960’s or 70’s. It is in excellent condition with hardly any issues and looks like it was not used much. The vinyl seat fabric looks perfect, but there are two tiny needle sized punctures and a tiny cut that is only around 1/16” long. These three defects are really hard to see except under close inspection. The only other issue with the stool is that after we acquired it and were inspecting it we found one of the casters was missing it’s ball bearings that allow it to swivel. After some searching at local hardware stores we found one that was nearly identical to the other 3, so we removed the old one and installed it. The stool rolls perfectly now and since the new caster is the same height as the other 3 it does not wobble at all. The last 2 photos show the slight differences between the old caster and the new one.
