US Patent 9220345 Pressure-relief pillows

The invention is directed to a device comprising a body that defines a first surface and a second surface and defines a first, second, third and fourth lateral sides. In one embodiment, the first surface defines a first aperture and a second aperture. In one embodiment, the thickness of the body along the first lateral side is greater than the thickness of the body along the third lateral side such that the first surface slopes downwards from the first lateral side towards the third lateral side. The device not only reduces the pressure on the tailbone or on the hemorrhoids for a person in a seated position, but also reduces the discomfort or pain associated with settling into a seated position or emerging from a seated position.
