I purchased 4 of these shelves to create a significant amount of storage in my basement. The shelves go together pretty easily, I used a hammer with a small piece of wood to prevent damaging the rails (couldn’t find my rubber mallet). Overall the shelves feel sturdy and strong. The only con is that the shelves don’t have any way to level them which mean the floor they are place on needs to be pretty level. In addition, I had an issue with one of the boxes being ripped and missing some parts during shipping, however Wayfair went above and beyond to make sure I got all 4 shelves in working order.
