I found two of these stools about 15 miles from Woodstock at a yard sale on Memorial Day weekend. I could have hit about 200 sales between Phoenicia and Woodstock that day.
The stools are made by Cosco in Columbus, IN and they seem pretty bullet proof. Cosco is famous for their kitchen step stool. The 60's chair/step stool that allowed ladies in high heels to get to groceries in hard to reach areas.
I guess ladies just aren't classy anymore.
These have a little wear on them but a little rust never hurt and the red vinyl looks great.
