Love the size and quality of this cat tree. Its perfect for 8ft ceiling height. Assembly was quick and easy, materials seem standard. Cat not currently interested in hammock options but we will see how she adjusts over time. My 8lb, middle age kitty loves this tree, climbing and hiding in cubbies. Great exercise and entertainment. Only draw back is the middle perch sticks out past the big cubby about 2 inches, so I cannot push it flush against the wall on that side (back). The extra anchor strap is great for safety if you have a permanent spot/wall - useful if you have bigger cats or multiple cats that could tip it, but it does not seem very tipsy/wobbly so far in the corner and on carpet where I placed it. Shipping & delivery were very quick and prompt and item arrived much sooner than expected. Well packed to protect materials.  WyFr communicates well about orders also, which is much appreciated.
