My three-year-old has a ton of toys. I live in a small house and googled toy storage ideas for small houses. This was one of the ones that popped up and I was sold. They're in my foyer as three of these would have been too much in my son's bedroom. The first one took over two hours but I was doing other things while I was working (texting, picking songs to listen to, etc).  The second one I was able to do faster, but I'm not going to lie, those wheels you have to put on the bottom are time-consuming. It took me 22 mins to put those wheels on.The third one, which I did the next day, was a breeze. I believe I was sitting when I put the wheels on initially and actually getting on my knees gave me more leverage. Still holds the title as the worst part of the building process. Oh and they did have minor flaws here and there, little blemishes and marks, but nothing glaring or worth returning.
