Abstract
Six-sided furniture parts are manufactured by pressing a cellulosic fiber-containing mat to consolidate said mat into a unitary blank, cutting the blank to a size larger than interior dimensions of a closed mold in every dimension and with two to four generally shaped or profiled edges disposed between a top surface and a bottom surface of the blank. The cut blank is then molded at a temperature of at least 500.degree. F. for a period of time sufficient to permanently transfer the interior shape and design of the mold cavity to every surface of the blank.
