I chose this for the height and the aesthetic. Love that it isn't covered in the usual ugly carpeting on cat trees. Easy enough to build by one person. Make sure you read the directions carefully because a lot of the parts look the same, but are different, and they're all individually labeled for clarity. The wooden shelves have rounded edges. There are 3 removable cushions with elastics to attach to the shelf. The cushions are soft but thin, so I may attach an actual bed to the top shelf. It is stable in the sense that it wont fall over, but it is a little wobbly when the cat jumps from each level. If youre concerned about that, it has a strap to mount to the wall.
