Bed was missing a piece. There were two pieces of wood on the inside frame that I was supposed to have 4x of each. I had 5x of one, and 3x of the other. I ended up just drilling a few holes in one of the boards and made it work. Secondly, if you're buying this frame for a Casper mattress, Casper recommends the slats are 4" apart at max. This bed frame has slats 6"+ apart. Again, easily fixed-- I added a couple planks in between. On the positive: It was fairly straightforward to put together. It took a lot of effort! But it was really easy to follow the instructions. And it's the correct size for a King size mattress.
