Tell you what. At least the ones I’d used were damn well built. The absolute beating those things took and withstood. Paint got chipped was about it. Maybe the arm drooped a bit from those days’ big kids.
This is tangentially related, as the Twitter thread focuses exclusively on seating, but if you're interested in the designers and companies that have shaped school and other aspects of children's lives, I highly recommend "The Design of Childhood" by Alexandra Lange.
I was working across the street from the high school today, and was watching some kids race down the street in office chairs. But they weren't cheap Costco ones, they were metal and obviously from the school. I was thinking that they must be really well made.
