The legs of my chair are broken and I want to fix them. One of the legs of the chair is broken. The leg is off of the chair and the screws won’t keep it in. because I fell off my chair because of it. The problem is located in my house. So no one else falls off the chair. You can probably print out another leg. The color would need to be brown or black.
