ABSTRACT:
The formation of wrinkles in bed sheets used on mattresses of the type having elevated side bolsters and the tendency of the sheets to come off when the mattress is articulated are reduced through the use of a fitted sheet having conforming pockets receiving the side bolsters. Stabilization of the upper sheet surface by the pockets is augmented in some embodiments through use of a stitch line placed along a seam on the inside of the pockets and/or by un-pocketed spans of the upper surface of the sheet connecting directly to an elastically retained skirt.
