Introducing my knex stool. The stool is 15" high, 15 1/2" wide at the base, and 12 1/2" wide at the top. As far as I have tested, it can support up to 200lb. When you sit on it, it may creak, but it has never collapsed when I've sat on it. I would suggest if you weigh over 150lb. that you should add a extra cross brace. Enjoy the pictures and please vote. WARNING! This is not a stool to stand on, it is a stool to sit on. Click here for instructions.
