Red Haired Girl In The Bed With Pillows

Orthopedic
Neck pillows support the neck by providing a deep area for the head to rest and a supportive area to keep the neck in alignment with the spine while sleeping. These can also be known as cervical pillows.
Travel pillows provide support for the neck and head in a sitting position. Their "U" shape fits around the back of the neck and keeps the head from slipping into an uncomfortable and possibly harmful position during sleep. However, U-shaped pillows can sometimes force the head forwards creating neck stiffness. They can also be known as a Bucky pillow.
