This is a natural wooden cat tower that uses driftwood for the pillars. The pillars and base are driftwood, but the type is unknown. The top board is cedar, and the other two boards are made of Japanese arborvitae, a very hard type of wood. The dimensions are: Height: Approximately 99cm Top platform: Maximum width approximately 34cm Second platform: Maximum width approximately 38cm Side platform: Maximum width approximately 24cm Base: Approximately 60cm x 44cm Because the packaged finished product exceeds the size limit (200cm) for shipping, the base, top platform, and side platform are detached. Therefore, we apologize for the inconvenience, but the customer will need to secure the base with 3 screws, the top platform with 3 screws, and the side platform with 1 screw using a screwdriver. The screws will secure them firmly, but if you are concerned about slight wobbling, you can eliminate it by applying wood glue to the gaps. It is coated with wax made from homemade Japanese honeybee beeswax, which gives it a nice shine. Thank you for viewing.
