This is a cat tree that uses driftwood for the pillars. The pillars and base are driftwood, but the type is unknown. The top board is Japanese cedar, and the other two boards are made of Japanese cypress, a very hard type of wood. The base is made by cutting off the root part of a tree with a chainsaw, and has a unique wave-like shape. The size is: Height: Approximately 99cm Top platform: Maximum width approximately 34cm 2nd 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 please understand that you will need to fix 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 putting wood glue in the gaps. We have applied wax made from homemade Japanese honeybee beeswax, which gives it a nice shine. Thank you for looking.
