Putting it together was quick and easy. The unit seemed pretty sturdy BUT I had meticulously sought long and hard for a wire rack that would fit my microwave on the upper middle shelves. Unfortunately the dimensions provided are for the outer most dimensions. The poles are positioned so they they take up a small amount of shelf space on each corner. There is only about 19" between poles on the width and 11.75" between poles on the depth. This seemed like a great product but unfortunately doesn't meet the needs of what I bought it for. I'll probably use it in the garage or shed- I bought it before I actually needed it because we just moved into a new house so now it's too late to return :(
