Looooove these shelves. I bought four of them because I have around 350 books right now. They’re beautiful, sturdy, easy to put together, and they’re the perfect height for me. I use the tops of mine for all my Harry Potter stuff but also for some plants. The shelves are a good sturdy wood, so they seem resistant to bowing under weight. Might need pliers and a hammer to adjust the little pegs, they can be hard to get inout of the wood. Overall, very very happy with these.
