This is a natural wooden 3-tier cat tree that uses driftwood for the posts. While the type of driftwood is unknown, the base is made of beautiful keyaki (Japanese zelkova) wood, known for its striking grain, and the platforms are made of hinoki (Japanese cypress). The dimensions are: Height: Approximately 129cm Top platform: Maximum width approximately 40cm 2nd and 3rd tier platforms: Maximum width approximately 31cm Base: Maximum width approximately 50cm Shipping via Kuroneko Yamato (Japan's parcel delivery service) is limited to a total of 200cm for the three sides. As this product exceeds that size, the top platform and base will be shipped separately. Therefore, the customer will need to attach the top platform with two screws and the base with four screws using a Phillips head screwdriver, but it's not particularly difficult. The driftwood has been repaired to address any dirt (especially seaweed and barnacle attachments) and scratches, and then coated with beeswax. Please feel free to ask any questions. Thank you for viewing.
