Thanks! We got it in a flatpack at Costco. This particular one is cedar, and after looking cedar up, Toby decided to go ahead and put the water sealant on it*. And the screw holes were wonky or something, which mean he ended up stripping one, so he went to the hardware store and picked up some metal plate things to join the top to the bottom. It's probably sturdier now than it would have been previously.

*Turns out old-growth cedar has internal oils and stuff that makes it extremely water-resistant, but almost everything available in cedar nowadays is young, and it hasn't built that protection up, so it's recommended to seal it.
