Maybe not great for big boys (or girls). I bought this so he could look out the window. It's the right height for sure. Top shelf is small, as you can see. It's not very sturdy though. I tightened everything as much as possible, but it's not designed with good balance so it wobbles when he stands up or turns around. Might have to attach to the wall somehow. I'm not happy with the exposed screw heads (they're not in any of the photos) but all in all this is a case of "you get what you pay for.
