Description

BACKGROUND

The disclosure generally relates to pillows or body support systems to support and comfort the human anatomy.
All sorts of pillows have been developed to support the human anatomy including for example pillows for the head, neck, and back. Pillows have been developed for supporting the neck while sitting, the back while sitting, and the head and neck while lying down, e.g., a bed-time pillow. Pillows have also been developed for sitting on.
The known pillows, however, have not provided the desired support for the human back while sitting upright, particularly for pregnant women, and thus have not reduced or alleviated the discomfort experienced by pregnant women. Also, the needs of the working pregnant women have not been adequately addressed. The disclosed pillow, body support or cushioning system has particular application to the needs of the pregnant women as they function and undertake their daily activities.
It is an object of the disclosed pillow or body support system to provide proper back support while sitting upright, particularly for pregnant women while sitting upright. These and other objects will become apparent from the disclosure and description of the pillow and/or body support system.
