This is a 4-tier cat tree made with natural wood. The pillars are driftwood, but the type is unknown. The platforms are made of: * Hinoki (Japanese cypress): Approximately 40cm x approximately 26cm * Sugi (Japanese cedar): Almost a 33cm diameter circle * Kaizuka Ibuki (Chinese juniper): Maximum width approximately 23cm * Kaizuka Ibuki (Chinese juniper): Maximum length approximately 40cm The base is made of Sugi (Japanese cedar): Length: Approximately 61cm, Width: Approximately 43cm Maximum height: Approximately 108cm Because the assembled product exceeds the size limit (200cm) for shipping, the base and the top platform are detached. Therefore, we apologize for the inconvenience, but you will need to attach the base with 3 screws and the top platform with 2 screws each from the top and bottom using a screwdriver. The screws will secure the pieces firmly, but if you notice any slight wobbling, you can resolve it by applying wood glue to the gaps. The tree is coated with wax made from homemade Japanese honeybee beeswax, giving it a beautiful luster. Thank you for viewing.
