MOVABLE SEAT CUSHION AND BACK REST In humans, the spine acts to stabilize the head. It allows the pelvis and chest to rotate in opposite directions, stabilizing movement of the head even while walking or jogging. To recreate this movement in car seats, the seat cushion and back rest were designed to move kinetically with occupant weight and external forces. Simply sitting in the seat helps stabilize head movement caused by vehicle motion, keeping the field of vision steady, improving ease of driving and comfort. SYNTHETIC SPIDER SILK The threads at the back rest of the spider web-pattern construction are made from environmentally-friendly, synthetic spider silk materials* instead of petroleum-derived materials. The main component of this material is protein, which is created through microbial fermentation, then spun and processed into a new material offering superior shock absorbance. *QMONOSTM material developed by Spiber Inc.
