Review on Premium FISH&NAP Cat Tree: Ultimate Cat Tower Condo with Jump Platform, Scratching Posts, and Play House - Grey by Alicia Fraser

It is very easy to assemble. I didn't want a tall cat tower. Only one fits perfectly on the edge of the windowsill. As you can see from the picture it is perfect. Each cat tower is unique, so just measure it and read the description. There was no padding on the top so I added a towel as you can see in the picture. Also easier to wash. My cat is small for her breed but she is stocky. Any less and it wouldn't work for her. She loves it. If you have more than one cat I would recommend getting a large cat tower.
