Took our handyman three hours to put together.  SO many parts.  Just be aware of this.  Any flat packed item is going to have lots of parts.  It's okay, not as roomy as we imagined it was going to be, but pretty handy having items in the bottom doors so that they come out to you instead of having to crawl inside searching for stuff.  We didn't anchor it because we may be relocating it, and also, we put towels in the top (we're using it as bathroom storage) and heavier items in the bottom.  Its wide base makes it pretty stable.  That said, we would think it's absolutely necessary to anchor it if you ever might possibly have a child in the house, even a visiting child.  Better safe than sorry.
