Provide mix of rustic and modern vibes
Size: 48in, Color: 3tier, Size: 48in, Color: 3tier
Absolutely love how these turned out! The black pipes and chunky wooden shelves give off a perfect mix of rustic and modern vibes. Super sturdy too—they hold a good amount of weight, so I’ve been using them for books and a few decor pieces. They’re really versatile—would look great in home office or living room as well. Assembly was easy, nothing too tricky. Overall, a great way to save space and add some style to the room!

Beautiful but…
Size: 48in, Color: 3tier
I have bought a half dozen of these shelves over the years and installed them in my own home and family members homes. They are beautiful once they are up. The quality of the pipe and wood are great, heavy duty. BUT Somehow I seem to forget that the installation is a complete nightmare-borderline not worth it. The pipe never likes to line up properly and when it does it’s just not tight leaving the whole thing feeling wobbly. Once installed it is very beautiful and sturdy. The other part I also seem to forget is that the anchors are complete and utter crap! Save yourself the frustration and TOSS THEM immediately. Its a huge waste of time attempting to use them and your so pissed off by the time you realize it that you almost don’t even want the shelf anymore😂 In summary- Beautiful, quality shelf but buy your own anchors and round up you patience prior to install.

I like to have a three-dimensional wall shelf at home. I can display plants, photos and other items well. It is great. I haven't taken care of it yet. I need to put more beautiful items. Oh, by the way, it is of good quality. It is a little heavy. The merchant provides expansion screws for hanging it on the wall. It is also very simple to assemble... I am very satisfied with the effect and I like it very much.
