Hard to assemble
Color: Grey
This is extremely hard to put together, but once its together it is pretty good. You will need to secure it to something. It falls over.

the best shelves

bought these after another set of floating shelves didn't work. these are great and an awesome value!! i've used these in my guest bathroom and also throughout my house. they look great everywhere and are much easier to hang compared to others. my husband was hesitant after the last shelves but these turned out amazing. they are very sturdy and hold a good amount of weight. i would recommend buying these compared to any others.

Great Wall Shelves – Sturdy, Easy to Install, and a Fantastic Value!
Size: 4 pcs: 15.7*5.7, Color: White
I’m really happy with these wall shelves! They’re sturdy, well-built, and hold up perfectly under weight—no concerns about them sagging or bending. The installation was super simple, and everything was clearly labeled with no missing parts, which made the whole process smooth and stress-free. I love that they come in a set of four, making them perfect for displaying books, plants, or decorative items in multiple spots around the room. The design is sleek and minimal, so they fit in with pretty much any style of decor. Overall, these shelves are a great value, and I would definitely purchase them again. Highly recommend if you’re looking for reliable and easy-to-install shelving!
