    Very easy to mount on the wall. Very sturdy with about 10-12 lbs on each shelf. Only took about 15 minutes to hang each one.

    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.

    Very nice shelves they look great up and were easy to install. Same color shown in picture. They seem very sturdy on the wall and I love the look of them. They are light weight and a good size just a little plunder 40 inches. Good quality for the price. I'll be buying again.
