Color: Black, Size: 35 Inch, Style: 3 Pack, Color: Black, Size: 35 Inch, Style: 3 Pack
Easy to install. Sturdy enough for 2 large rambunctious kitties to play on and look very nice. I was working on a vertical play space for the cats and since these come in many sizes it worked great. I did add grip tape to some.

Not the best quality
Color: Rustic Brown, Size: 35 Inch, Style: 2 Pack, Color: Rustic Brown, Size: 35 Inch, Style: 2 Pack
The shelving unit was not as I had expected. It arrived damaged. The damage is on the under side though. They are hollow and not hardwood as I had expected. Save your money if you want something of good quality. These are like 3 pieces of pressed wood glued together. They are space saving and look great in my space. The mounting hardware it comes with was plenty enough to hang these but make sure you hang them in the studs if at all possible. Assembly was simple. It does come with a micro level. Which a kid or pet could accidentally swallow. It’s like pill capsule sized so just be careful when opening the package.
