Abstract: A blanket support device slidably insertable between the mattress and box spring of a conventional bed. The blanket support device extends outward from the mattress providing a surface area for placement of blankets thereon. A leg support is formed integral and hingeably secured thereto to maintain the blanket support in a horizontal position should blankets of heavy material be placed thereon. The leg support is adaptable to different size beds by trimming a portion of the leg support along a pre-defined location. The leg support may also be rotated into an upward position providing a blanket support so as to raise the blanket above an individual's feet during the sleeping process. The blanket support device is stored by placement of the leg support into a horizontal position allowing insertion between the mattress and box spring.
