I am using 4 of these, stacked 2 high. They work great for what we need. I put them together by myself easily enough, but 2 people would have made it easier and faster. There are a lot of screws. I am able to put 5 pairs of shoes on one shelf, angled down. I put them together so they are flat for my husbands shoes and can get 4 pair per shelf. They are very sturdy!
