This is such a sturdy and nice unit! The directions were easy to follow, and it went together quickly. The middle shelf is able to adjust to the height needed. I altered the unit a little bit, leaving off the casters and building it inside a closet for hanging and shelving space...it works great and is just what I needed. I may buy another unit and use it as intended, as a freestanding rolling garment rack. It is a pleasure to find something that is as nice or nicer than its description! This garment rack is great!
