Legs seem decently thick. They could be a little sturdier. The paint has stayed with no chips or flakes. Color has not faded. It sits at the perfect height for a desk. Screws and hardware do the job. No welds to speak of, everything screws together. I’ve used these for a year and a half as a school desk and has held up well. I took a sheet of project board with stain and polyurethane as my top. Works excellent
