I purchased this step stool because I am only 4 ft. 111/2 inches tall...lol. The one I currently have is so so hard to open and hard to store and will rust if left outside. This Cosco 3 step step stool is sooo sturdy and very easy to carry and open, you can almost open and carry it with one hand! I don't recommend this but if left outside it probably won't rust because of the rubber type coating on it. The only thing I noticed is that the bottom step is just a little wiggly but once you step on it, it's good and sturdy. Even at my height if I stand on the top step I can reach the ceiling. If you stand on the second step and don't need the top step as a step you can use it as a tray/platform for holding items...it is a bit wider than the other two steps. When folded it stores very well in the smallest of spaces like between the fridge and cabinet. I am TOTALLY satisfied with this 3 -step step stool!!
