Pretty and practical
Color: Rustic Brown, Size: 31.5 Inch
I love the rustic wood and iron look. It’s sturdy, spacious, and exactly what I needed in my basement apartment. I ended up buying another one to make it one long shelving unit. I highly recommend them!

Very handsome and functional shelf with a ton of space!
I was looking for a black wall shelf to go above our coffee bar that included a bar with hanging hooks for empty glasses and a bar towel. This shelf met those needs, and I'm very impressed with it overall. It's a bit pricey for how simplistic it is, but it doesn’t feel or look cheap. Assembly and installation with the provided hardware was easy with help of a drill. The shelves are deep and work well for storage baskets and larger items. It’s a sharp-looking piece that really improved the look of our expanded coffee bar.

Wonderful shelf but difficult to install!
Size: 41 Inch Extra Long, Color: Rustic Brown, Size: 41 Inch Extra Long, Color: Rustic Brown
I absolutely love this shelf. It's perfect over our coffee bar and is extremely sturdy. Assembling it was very easy, but hanging it was challenging. The design could definitely use a little improvement. My husband had to order an angles drill adapter to be able to get the screws in. He also bought different anchors than what came with it. But now that it's up it looks fantastic!
