I dug up the root of a tree that had fallen from the mountains onto the coast and was buried in the sand, and brought it home. I used this as the base to create a 3-tiered cat tree. I don't know what kind of wood the base is, but I used natural wood (the top tier is Japanese cypress, the second tier is cedar, and the third tier is Chinese juniper). Size: Maximum height: Approximately 77cm Maximum width: Approximately 80cm Top tier (almost rectangular) Approximately 37cm x Approximately 25cm Second tier: Maximum width approximately 33cm Third tier: Maximum width approximately 36cm Due to the size of the product and to keep it within the 200 size for shipping, the top tier has been removed. Customers will need to assemble it. It can be securely fixed by tightening two screws with a Phillips screwdriver. Also, holes have been drilled in the base pillar, and support rods are inserted for easy stability. In addition, I made a wood wax using beeswax from the Japanese honeybees I keep as a hobby, and I applied it overall, giving it a nice shine. Please feel free to ask if you have any questions.
