I searched in stores and online for a nice sturdy tall, wide and deep shelving unit. Not only does it fit all those criteria but it was so easy to put together with no screws or tools needed beyond a soft headed mallet. We bought 2 units to put side by side in our basement work room. Everything is now up off the floor and neatly stored. My husband and I put them together quickly with relative ease. Can’t tell you how happy I am with them.

Pretty heavy duty, it holds up to heavy weight from raw bars of Aluminum, Brass, and plastics for my shop. You can arrange the shelving to make long shelves or stack them to have 5 tiers. You can adjust the height of each individual shelf for storing totes or whatever you want with different heights, short or tall.
