I worked with metal studs with the help of an installer and the requested hardware in shipping. I emailed Elexis an embarrassing amount of times with questions and her response is very helpful. Between the unboxing/inventory, pre-assembly, install, and re-evaluation of the furniture, it was certainly a process, but one very worth the investment! I have 5 cats and all together 5 pieces from Catastrophic Creations. I live in a small apartment so I especially wanted to take advantage of vertical space. Over the past two months the furniture itself is durable and can withstand daily use with a minor setback with screws coming loose from the wall. This was fixed with zip togglers provided by an install service. I am still in the process of getting all of the studs fastened down in this fashion. I like that the store has extra replacement pieces, the diversity of the furniture offers all of my cats satisfaction from boredom. All of them used it right away. Future consideration should include 3D modular configuration software that would have allowed for the pieces to move around and applied to a "see how it looks on your wall" before purchase. I had a real hard time visualizing how to create my own design outside of the suggested templates without going over on space while also keeping it functional. All in all, a great unique find that enhaces the quality of life to our home! Thank you, Catastrophic Creations!
