Both elevated beds are wobbly enough that our cat does not stand or rest on them. The base of the pillars are as tight as they will go, but there is still enough play to allow the pillars to rock, and consequently also the beds. Our cat is a jumper and loves sleeping in high spots, but not these beds, even with catnip inducement.  Another area that could be improved, is covering the smooth, hard inside walls of the "cottage" with the soft fluffy material that is used on all other surfaces.
