Abstract: An example easy change mattress sheet attachment system includes a bed sheet having four sewn-on fabric casings in an arch shape and a cord inserted through the casings forming a set of accessible sections of drawstring at exposed between-casing cord regions at four corners, and a bottom mat having means for trapping drawstrings at four corners. After having installed the bottom mat under the mattress, one can install and remove the top sheet onto and from the mattress without having to lift up the mattress. To install the top sheet, first put the top sheet on the mattress, then execute drawstring-trapping maneuvers at four bed corners. To remove the top sheet, detach the engaged drawstrings at four bed corners.
