Unbearably cheap wood. Braces were warped in the box. When trying to adjust shelf (with not very much pressure) it broke as you see in the picture. If it were made with better wood, this would be a very good piece. As is, it was WAY TOO EXPENSIVE. This, as is, should cost no more than $12-$15. Then hope you're lucky enough not to break it. Treat it like an infant.
