I have a few different sizes and colors of these types of racks. I like the one’s that have wheels so you can unlock them and move them around if you need to.  These are super easy to put together,  just make sure the pieces that hold the shelves in place have “top” at the top of the piece when putting on bars, and they’re all the same heighth on adjacent bars, and your good to go. Make sure to screw any addition bars together before adding the last few plastic holders and the last one or two shelves. The shelf heights are adjustable so you can store a lot of different items, and they hold a lot of weight.  Easy to clean and look nice.
