The top has been cut into a large circle using a router and a circle cutting jig. The top also has semi circular retention sides that prevent the chair from sliding off the platform. The base is has been cut into 3 inch wide strips and glued up into an octagonal frame that is attached to the top using pocket hole joinery.
