Stretchable bedding components reconfigurable between a neutral or retracted configuration and an expanded configuration. In example embodiments, fabric is cut and sewn to form one or more bedding components with at least some dimensions being about 5%-30% less than those of conventional or traditional bedding components. In example embodiments, the length and/or width of the bedding component is expandable between about 5%-30%. In example embodiments, the stretchable bedding components include a biocomponent yarn having a helical structure that imparts elasticity therein so as to permit stretching of the one or more bedding components.
