My cats loves these! Used them in combination with other Wayfair cat furniture. Mounting was easy, I made sure to hit at least one wall stud, and the shelf came with the needed drywall plugs for the second mounting screw. Like another review showed, there were gaps in some of the areas where the seat area attached to the support bracketwall mount board, but I happened to have a tube of caulk handy, so I ran a bead of caulk along the seams and now they look great. We have eight indoor cats, and these are holding up well, even with our chunkier fur babies.
