A pillow has traditionally been used as a head and neck support providing relative comfort in the alignment of the cervical spine while lying on one's back, side or prone position while resting or sleeping. Improvements to the traditional pillow configurations and structures have been made to provide a better positioning of head and neck while lying on the pillow. These changes were made in order to provide a comfortable resting position as well as orthopedically correct alignment for head and neck. To do so a number of curvatures and shapes has been introduced to the traditional pillow structure. The TRAINING PILLOW is invented by considering these changes as well as addition of a certain considerations to provide the ultimate comfort and orthopaedic support. The fact that each individual has different neck and shoulder size has been ignored in all the pillows invented to this time. It has simply been assumed that one particular pillow size can provide the best support and comfort for every one as long as it provides a certain curvature. Although introducing certain curvatures in a pillow promotes proper head and neck positioning, size of the pillow's height and curvature has determintal rule in achieving comfort and support. Moreover, the position of body and consequently head and neck while lying on the pillow has been also ignored in the previous inventions. They have simply assumed that the same curvature is sufficient for lying supine (on the back), lateral recumbent (on the side) and prone (on the stomach).
