Bottom board in two spots indicated the boring process for locking the sidewalls in place we’re too deep. When tightening sidewalls in place illustrated swell/bulges in show side of bottom board. I called for parts and was told there is no bottom board available and to package everything up and contact Watfair ??? Of course everything was totally assembled and there was no way I was going to disassemble .. but not happy fhat I cannot get bottom board!!!
