Car seat impact on driver's sitting behavior and perceived discomfort during prolonged real driving on varied road types.

Prolonged driving under real conditions can entail discomfort linked to driving posture, seat design features, and road properties like whole-body vibrations (WBV). This study evaluated the effect of three different seats (S1 = soft; S2 = firm; S3 = soft with suspension system) on driver's sitt...
