This is a beautiful shelf--easy to put together; lovely, solid wood shelves.  My only criticism is that once it's standing (per the instructions), it's impossible to tighten the screws on the bottom shelf without moving it up to the table again, but that is a very minor issue.  With the exception of moving it down to the floor, I did everything by myself: I am an over-65 aged woman.  It did take a bit longer than 30 minutes, probably close to 2 hours, but much of that was the figuring out how to accomplish a couple of tasks alone rather than actual construction.  If you're looking for a solid shelf that is "open" in feel, this one is what you want.
