Review on 🐱 Enhance Your Indoor Cat's Playtime with rabbitgoo's 38" Tall Adjustable Base Cat Tree - A Multi-Level Condo for Small Kittens, Includes Scratching Posts, Large Perch, and Climbing Stand! by Matt Pratt

The quality is a little worse than I hoped, one of my biggest complaints. The top stacking platform has no continuous side walls. It's just a sewn tube of lint that doesn't hold up very well. My cats shed it, it doesn't hold up that well. After a while, one side sags halfway. They could have given you really solid sidewalls for the top main stack area, but they didn't. I wouldn't buy this again for myself. It's not difficult to assemble, although I find it a bit awkward with a movable floor. I would prefer a solid base.
