An adjustable bed sheet includes a sheet made of a first material. The sheet spans at least the length and the width of the mattress. A perimeter of the sheet is defined by edges thereof. The bed sheet also includes an elongated strip made of a second material that is more stretchable than the first material. The strip has a first elongated side opposite a second elongated side. The strip is attached, via the first elongated side, to an edge of the sheet such that, when the adjustable bed sheet is applied to the mattress, the strip is positioned, with respect to the mattress, to extend around at least one corner of the mattress from the length side of the mattress to the width side of the mattress. An end flap is attached to and hanging from the second elongated side of the strip.
1. A bed sheet sized to cover a mattress defined by a dimension that extends in a first direction and a dimension that extends in a second direction that is perpendicular to the first direction, the bed sheet comprising:
a first sheet portion sized, with respect to the mattress:
to extend in the first direction of the mattress across a surface thereof, and
to extend in the second direction of the mattress across the surface thereof to include hanging portions that hang over opposing first and second sides of the mattress, respectively, so as to hang off the mattress in the second direction;
a second sheet portion attached to the first sheet portion at an end thereof that extends in the first direction so as to hang over a third side of the mattress, the third side separating the first and second sides, and the second sheet portion having elongated segments that extend wider than the surface of the mattress in the second direction on both of the first and second sides,
wherein each elongated segment of the second sheet is attached to an underside of the first sheet portion at the respective first and second opposing sides the mattress, such that the elongated segments extend in the first direction while hanging from the opposing first and second sides of the mattress beneath the respective hanging portions of the first sheet portion,
wherein a third sheet portion hangs from an end of the second sheet portion.
2. The bed sheet of claim 1 , wherein the second sheet portion includes a material different than the first sheet portion.
3. The bed sheet of claim 2 , wherein the material of the second sheet portion includes elastane.
4. The bed sheet of claim 1 , wherein the third sheet portion is formed of a same material as the first sheet portion.
5. The bed sheet of claim 1 , wherein the second sheet portion includes a slit opening positioned to allow air to escape from under the bed sheet when applied to the mattress.
