Kinda flimsy…
Thought the assembly was metal, it’s some kind of PVC.

Stacking shelves
These work perfectly, even in rooms with high ceilings. One thing I didn’t really see mentioned or highlighted anywhere is that they can be stacked. I decided to try it anyway, and it turned out awesome. I purchased two units and placed one on top of the other, which essentially created one tall shelf. It ended up being a great way to maximize vertical space and made the setup look much more custom and intentional

Do not hesitate!
I was hesitant with some reviews saying it comes with scratches. This was packaged extremely well and it only had one or two very minimal scratches that you barely can even see. It is very sturdy and took about 40 minutes to build. It looks amazing and is not bulky but holds a lot which I love. After building this one, I immediately ordered a second one to go on the other side of my window. My son walks in and saw this bookcase and now wants one for his room, so I will be definitely ordering more.

I love this shelving unit!
We recently moved into a smaller home and I was struggling with storage. I found this and I’m so glad I did. It looks so good and I was able to assemble pretty quick, I think like 20 mins. I still need to get my husband to attach it to the wall but it’s the prefect size for my space. The only thing I wish was better is the instructions to assemble. It’s really easy once you figure it out but the instructions are just a few pictures on a small piece of paper. I love it!!!
