difference about 11.1 (14.83.7) cm from head to bed surface in
crown plane and in sagittal plane. That means when lateral sleep, a
pillow height of 14.8 cm is needed for compensation to maintain
spine in natural position and when supine sleep, a pillow height of
3.7 cm is needed for compensation to maintain spine in natural
position. The difference of pillow height in lateral and supine position
is as many as 11.1 cm. The length from neck to wall is 6.7 cm
and from hindbrain to wall is 3.7 cm. For the same reason, an
additional neck support with 3.0 (6.73.7) cm is needed for
compensation in supine position.
For the female, the stature and weight are 158.6 cm and 57.5 kg.
This is similar to the Taiwanese stature and weight (156.7 cm and
