I have 2!
Color: Coal Black
My office is in my loft. But there are things along the wall I don’t want to look at. These work great. Hides what I don’t want to see & is a classy look in the room. Sturdy, easy to assemble, well made.

Horrible Product, Even Worse Packaging!
DO NOT BUY THESE! These are junk. Cheap wood - like balsa. Poorly packaged - no protection between wood and packaging. Crap experience, lesson learned!

Cute tall shelves but not depth enough!
These are nice, but although they aren't depth enough from the wall. They are no bigger than 2.5-3 inches depth. If you have photos or any other narrow items, you'll be perfectly happy. But for books they are not good at all. Unfortunately I returned them.

Misinformed dimensions
This product misinformed me of size. It’s 47.235” in length not 48” as advertised. This is just another means of manufacture cheating customers with false information. I did not return as I was just moving into home. I was also in a hurry to finish the installation since I bought three of these not knowing the truth. You can make your own choice but I needed 48” and paid for 48” and got shorted. I used the shipping box to make an template to install brackets that manufacture did not provide.
