This Step is used in our home.  My wife is 5'1" and I can't always be there to reach the tall stuff.  This was purchased specifically for her and she loves it.  We have completely hardwood/tile flooring so moving the step around on it's spring loaded wheels is easy.  Not only is it a step, but a decent stool when needed as well.
It arrived in two parts and was extremely easy to piece together.
It is a strong step and even supports my large frame.
Overall, worth every penny.
