The construction is sturdy, and while this isn't solid wood, it's better made than the standard particle board.  The instructions to put this together are pretty straightforward and simple, though there are a couple of small issues.  One, some of the pilot holes aren't drilled well so thy can be a bit tough to locate and two, there's one place in the instructions where is says to use screws where nails are called for.  Once you get past those small issues, everything fits together well.  It comes with both casters and feet so you have a choice as to which to use.
