Redesign Rational: Exceed the level of comfort and compliance, while maintaining the effectiveness of Gen I with the following improvements:

• Increased lateral stability by adding width and an additional rigid foam perimeter enclosing a soft support center pillow

• Perimeter foam also increases the head and neck support for more ergonomic head/neck positioning

• Improve longevity by removing 'strap and button' connection

• Ease manufacturing costs by reducing the amount of stuffing in the head component

• Unibody unit allows for easier customer manipulation and easer case removal for laundering

• Changed to a 3-layer internal foam stack to improve long-term support while maintaining comfort

• Sleek, professional/medical-grade appearance
