Each shelf holds up to 15 pounds, and reviewers recommend putting your largest, heaviest books at the bottom of each shelf for more support.

Promising reviews: “These are so much fun! We ordered the small size, which fits standard hardback books (approximately 5–7 hardbacks in my experience). They’re a great way to add some extra storage to our very small home, and we’ve placed them in our hallway so people ask us about them all the time. I’d highly recommend!” —LaBuenaVidaMere

“I bought two of these in 2010, and in the last 10 years, I’ve used them in three different apartments. I just put them up in apartment number three and was once again blown away with how awesome they look. Every time I put them up, it’s like, ‘WOW WOW WOW these are AMAAAZZINNGGG!!‘ If you love decorating with books, this is a must-buy!”  —Jlands
