This was extremely easy to put together. Literally all you do is put the sides on, then climb yourself up inserting each layer which gets into place with hex screws. The hex screw turns easily, and like that over your traditional screws. It took 10 minutes of minimal effort, nor did you need instructions. Even the shelves are dual-sided so can't even go wrong there.
My only complaint is that I cannot put 3 pairs of size 11.5 shoes in them. It is just about 1” short of that in width. So I can either have them facing different directions, but all facing inwards is too snug. I don't feel 11 is even remotely big, so you'd only get two pairs unless my Nike's just happen to be larger but they are regular running shoes.
For the price, value, and ease of assembly (which I despise point things together), it's a perfect 5.
