READ the article before commenting. DRUNKS? All stairs are dangerous when you're drunk! Cantivered thick steel plates welded to angled steel beam with additional steel stiffeners WAY stronger than your flimsy standard plywood stairs. THE DANGER is what keeps you safe. Mentally you will naturally slow down, walk on the wall side away from edge. KIDS fall down normal stairs all the time even will code required handrails / guardrails. BEAUTIFUL feat of art & science in one.
