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.

12. The device of claim 1 , further comprising a bridge positioned at least partially in the first aperture, the bridge being configured to prevent the sides of the aperture from separating.
13. The device of claim 1 , wherein the body defines a fourth lateral side and wherein the body is substantially symmetrical about a line of axis that passes through the first aperture and is substantially parallel to at least one of the second lateral side or the fourth lateral side.
14. The device of claim 1 , wherein the body is constructed of high-density foam.
15. The device of claim 4 , wherein a width associated with at least one of the second lateral side or the fourth lateral side is not equal to the length associated with at least one of the third lateral side or first lateral side.
16. The device of claim 1 , wherein the body further comprises an aperture to inject a pillow-filling material into the body and to remove pillow-filling material from the body.
17. The device of claim 1 , wherein at least one of the first and second lobes has a thickness greater than a thickness of the body adjacent the at least one of the first and second lobes.
