The arch does not securely fit into the stand and there are only two drill holes, one of which wasn't even drilled all the way and the arch just gets pushed into the holes, no screws or anything to secure the arch to the stand, so anytime my cats try to push against it the arch falls over/off and is pretty much useless as something for them to brush against and walk under. My cats still like rubbing their faces on the arch part but I have to hold the arch up for them to rub against it.
