The Importance of Differentiated Density Foaming in Long-Distance Driving

Core Principle: Softness does not equal comfort; support is key. Differentiated firmness is used, with each layer addressing the specific needs of the next. This ensures even pressure distribution, reduces muscle compensation (S_s), provides vibration damping and cushioning, and enhances safety. In a collision, the different density foam deforms as expected to absorb energy. During sudden braking and lateral movements, the high-density areas in the side wing provide support and reduce body sway. Differentiated density foaming allows the seat to adapt to the body, rather than the other way around. A gentle surface, shock absorption in the middle, and support in the lower part primarily address the issues of sinking into the seat and a hard, uncomfortable feel on the buttocks during long journeys.
