From my Patent Application 08/2023:
Swan Neck Cervical Deformity (reversal of normal lordosis)
For years my sleeping position mirrored the sleeping position in foreign patent JP 2011-240098. The person’s head is only supported on the forehead. In subsequent pictures the person uses their arms to support their head. In this position the weight of the head is not completely supported and the effect is for the chin and jaw to pull downward, while the forehead tilts upward in relation to the body. Over time you could damage the vertebrae in your neck, like I did.
Surgical Repair Swan Neck Cervical Deformity
Repaired Cervical Lordosis
The cervical deformity was the driving factor for me to invent the Pure Prone Position (PPP) mattress. When I filed the patent in August 2023, I knew the numbness in my arm and tingling in my fingers was getting worse. By December 2023, I was informed I needed surgery As Soon As Possible (ASAP). The surgical repair was completed in March 2024.
