Easy to assemble. Lots of fun things for my cat to explore. I'd been looking for a nice cat tree at a reasonable price, but having a hard time. When I saw the cat tree online I was excited but skeptical. Upon opening the box and checking out the pieces I was impressed that everything I needed came in the package. The quality of the tree really impressed me and the price was far less then anything I had seen before. Im truly impressed with my purchase and I know my cat will enjoy it in years to come.
