I work at a veterinary clinic and we needed a narrow shelving unit to store extra cases of cat food. This is absolutely perfect. It is extremely sturdy and seems like it will hold up for many years. Being able to choose different heights and add on extra shelves allowed me to customize it to fit in our space. The 14 inch deep and wide shelves are really hard to find, so I was really excited to be able to order exactly what I needed. The unit arrived quickly and assembled easily.
