By Liz White, UT staffUS neurosurgeon Joseph Berke has designed a pillow made of viscoelastic polyurethane foam that not only has the now familiar lop-sided balloon-shaped contour for good neck support, but also has cut out areas underneath the pillow. These allow users to put their arms in various positions, giving relief from neck and shoulder pain. Berke patented the 'Sleep Better Pillow' following his own private battle with arm, shoulder and neck pain, according to the bettersleeppillow website. The retired neurosurgeon said in a company statement that conventional and orthopaedic pillows made from latex foam, polyester, and goose feathers did not work for him, so he decided to invent one himself. The innovative pillow has a cut out all along the front width of the pillow. This can comfortably accommodate a person's shoulder. The centre is also tunneled right through, allowing a person to put an arm right underneath their head. Also, the sides are sculpted to accommodate those who prefer to sleep on their stomach or side. Whether a sleeper lies on their stomach, side, or back, this design "evenly distributes and reduces pressure on a person's arm, shoulder, and neck," also helping align the head, neck, and spine for improved breathing, claims the bettersleeppillow statement. This in turn, keeps the nasal and throat air passages open, reducing snoring as well as sleep apnea-a disturbing condition in which a sleeper stops breathing for a while, and then gasps for breath. "
