Steel is strong in slim sections, so the stool looks light while carrying a heavy load; it does not swell, crack or warp with kitchen humidity; and a baked finish wipes clean and resists chips. It is also the material that allows custom seat heights.
The weak points of cheap metal stools are not the steel but what is done with it: bolted joints that loosen, thin tube that flexes and wet paint that, in our experience, can chip at the footrest within months. Check those three things, joints, tube and finish, before the look. Our guide to wood vs metal bar stools compares steel with oak.
