This is a super solid shelving unit that is fairly simple to put together. You will never worry that it is going to bend or break due to putting heavy items on it, as has happened to me, using flimsier metal shelving. It is great for basement or garage storage of heavy items - honestly I was not aware that they made such sturdy shelving available commercially, but I will likely buy more to hold more of my storage bins. I will have these for life! And I wouldn't want to toss them (as I have with other shelving that bent or rusted). Be aware that this sturdiness is the result of the unit is extremely heavy - like 125 lbs total? - I could not carry it by myself. I ended up having to carry it in pieces to my basement before I assembled, so that was not ideal, but that is what required for such sturdy shelving.
