I’ve had this up for about a year along with other lotus leaf shelves, and they are really awesome! It took my cat a few weeks to figure out that it was ok to be up there on the wall, catnip helps. They are well made and sturdy. They mount up in a few minutes and it’s pretty self explanatory with everything you need. I used power tools to speed it up and you will need a helper to hold them while you secure it. My favorite thing about this is that it satisfies my cat with a high safe place to go to In uncomfortable cat situations, like company, vacuum cleaners, etc...,at the same time it’s really very attractive a wall decor so you don’t look like the crazy cat lover you are. Make sure you measure your space and check for stud placement, they are substantially made.
