Looks Fabulous!
Love this shelving unit. The golden honey with dark colors wood looks real even though it's a laminate. I like the open look. It's strong and holds a lot. Super easy to put together. I absolutely love mine.

Very cute
I really like the look of these shelves. They are very cute and give that 'industrial' vibe to my kitchen. The assembly instructions are absolutely useless. The shelves are pretty straight forward and I was able to assemble simply from looking at the picture of the finished product. Really like that they bolt into the wall.

No regrets
Went together perfectly in no time. I would say that builds best with two people. Incredibly happy with this purchase. Arrived when it said it would! Very pleased 😀

It's a perfect shoe rack for a small apartment!
The quality is good, and the shelf looks perfect. It also fits exactly how it should in my studio apartment!
A maintenance guy has put it all together and up within 45 min!
I'm very happy.

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
