I purchased two of these boxes for my patio and they are huge and sturdy and water proof. I can lay on them and don't feel like I'm compromising stability. They were easy to put together (with two people made it super quick) and the hing system makes it easy to open an close without pinching fingers. Make sure to put some sort of lock or closure on them to prevent the top from flying up in wind storms, we noticed it during a huge storm it blew it open twice, which is understandable.
