Metal step stools

My cousin is about 4"11 height and sometimes her husband joked about how tiny she is that she can't even reach some stuff in their kitchen. Her husband once had joked about getting a metal step stools for her to use whenever she needs to reach the spices up at the cabinet. I don't see anything wrong about it though. I personally have to buy them myself as i have also the same problem reaching items i needed specially the spices in the kitchen that are hiding back in there, gotta have them for sure.
