The rotational movement of seat cushion and back rest simulates the fundamental spinal movements of human mobility to help enhance head stabilisation.
In humans, the spine acts to stabilise the head. It allows the pelvis and chest to rotate in opposite directions, stabilising movement of the head even while walking or jogging. In order to recreate this movement in car seats, the seat cushion and back rest were designed to move kinetically with occupant weight and external forces. Thus, simply sitting in the seat helps stabilise head movement caused by vehicle motion, keeping the field of vision steady. This reduces the burden on occupants, improving ease of driving and comfort.
The spider web-pattern flexible net closely fits body shape, dispersing load for prolonged seat comfort and optimal body support.
The seat frame “upholstery” comprises a spider web-pattern net with threads that spread out radially from the center of the backrest. The net is sufficiently flexible to closely fit body shape, dispersing the load to make it possible to sit comfortably for prolonged periods.
The centre of the back rest is at shoulder blade height, which induces rotational movement of the chest around the seat’s pivotal axis. This helps to stabilise the head and ensure a high level of support. The seat has also been made slimmer, making the overall car lighter in weight.
The threads at the backrest 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 properties. 
Opel is obsessed with seat engineering.
