Sturdy. Good looking and easy to assemble. The only problem is that the pictures do not show that this item is missing the corner that actually touches the wall which leaves a hole just big enough for your cat to run in and out of all day long which makes it really hard to use since they want to hide and play in it all day.  Ended up setting up a television in that space stuck to the wall permanently with a shelf above it so that my cats would finally leave it along. Other than that, nice desk.
