When our senior cat found it difficult to get to her favorite location, this stair way was perfect. It is lightweight but stable so you can move it wherever. The fact that it folds is a big plus       when it is not in use you can just tuck it away under a bed or in a closet.  We purchased a second one for our other cats who like to use it as a perch by our family room sliders. Well priced, well made.
