All wood indoor and outdoor trees
The Outdoor trees are built with western red cedar for longevity. The indoor trees are made with spruce. The standard tree will be polyurethaned (water-based) or left untreated (by request). The platforms are circular and flat, as shown. All of the Classic trees and the Stratus trees designs (without enclosures or ramps) can be made for indoor and outdoor use.

This is the four-tier Classic tree with a large top platform in western red cedar. The lower levels are 16 inches in diameter and the top platform is twenty inches. The base is also cedar, twenty-two inches square.

This the five-tier Stratus, five feet tall in cedar.
