This cabinet was purchased with the smaller wall unit that matched it perfectly. A friend put them both together in record time. Since I rent, I did not attach the smaller upper cabinet to the wall but rather set it on top of the standing unit and they both look very comfy in my bedroom corner..They are very stable and sturdy but I would not set them on top of each other if small children or pets live with you. I live alone so the risk factor of them being knocked over are slim. Highly recommend and great quality for little cost!
