A lot of my books fit on here and there’s still more room left if I wanted to buy more books. It’s a simple looking bookshelf but it’s really pretty. It’s also sturdy the only reason I gave it a 4 stars instead of 5 was because it comes with its own plastic screw anchors and they are crap. The shelves were wobbly when we installed them using the plastic screw anchors that came with the packaging. My dad set mine up and luckily he had a bunch of his own so he switched them out with better screw anchors. Once we made that switch it was perfect, there was no wobble or shaking at all. So that’s my only piece of advice. Besides for the screw anchors everything else is perfect

Super easy to install. I use different wall anchors. The anchors like all anchors that come with shelves are not great. The shelves look very clean on the wall.

This product exceeded my expectations. The installation process was incredibly straightforward—even for someone with little to no experience—and the instructions were clear and easy to follow. Once installed, it feels very sturdy and secure, with no wobbling or shifting at all. You can tell it’s well-designed and made with quality materials. I also appreciated how quickly I was able to set everything up without needing any extra tools or help. Overall, it’s a reliable, user-friendly product that I would absolutely recommend to anyone looking for something dependable and easy to install. Drill is required though.
