I didn't notice that this cat tree is better for the corner of a room than next to a window. The perch sits at an angle on the platform - I didn't look closely enough at the pictures to see it cannot fit parallel to the window as I wanted it to. It was easy to assemble, seems sturdy, and is a compact size while the perch and box are large enough for my 16 pound male Siamese. Unfortunately, he quickly destroyed the rope portion of the support pole but he loves to scratch frequently. This is an okay product - just not what I had hoped for and would not re-buy.
