I see these for sale all over the place:
And I always feel surprised at the prices they fetch. $150-$300.
These chairs were common when I was a kid. We had quite a few of them, but they were inexpensive, and fiberglass wasn’t thought of as a “classy” material, so we tore them up! I mean, we’d lean back in them, leave them sitting out back, and basically were difficult on them. Abuse them enough and the legs pull out of the fiberglass.
So whenever I see them selling for over $25, and they always do, I have to chuckle about how we thought of them as just cheap old chairs!
