Holy smokes......I am going to be scared to sit in a chair ever again.
I think I'll start sitting on a phone book.
In the mean while the chair made right after that one won’t stay up.
There was a kid in my high school class who was leaning back on a high metal stool. It collapsed and one of the pieces went directly up his keister—deep. They had to call an ambulance. I never sat on one of those stools again.
