We really like it, and our cats LOVE it. However, I am very concerned about one of the platforms. Right from the start (when we assembled it), the platform post was already leaning and wobbly. When our cats climb on the platform, it sways quite a bit. This extra stress and movement isn't good for the plastic disc which holds the screws in place (located on the end of the post). We have had other cat trees (different brands) and they are a similar construction but have larger, sturdier posts (circumference of 9.5 inches vs. the 8.5 inch posts on this cat tree). I'm not sure if that is a factor here, but it seems like a thicker post would offer a bit more stability.
