The Idea's rear seats combine 40:20:40 split/folding and 60-degree-reclining backrests with a 60:40 split, folding and sliding seat base — the rear seats slide forward or rearward to prioritize cargo or passenger space, recline for comfort lounging, as well as fold and tumble for maximum cargo. The front passenger seat folds flat to receive tall items and 25 storage compartments are distributed throughout the cabin. The Idea's seating was designed using biometric principles developed by Antonio Dal Monte at the Italian National Olympic Committee's sport medicine institute.
