The seat is way too small for an adult. Could be used for a small child

This stool had a weight limit of 330lbs. I used it today for the very first time. My weight is 225lbs. This piece of junk crumbled under me and I fell, not only injuring myself, but also feeling humiliated as I was on a public fishing pier along with about 30 strangers. I could make this worse, but I'm an honest man. My elbow will heal, as will my pride, but I'll be dammed if I pay to return this broken rubish!
