Xiaomi SU7 Nappa Leather Seat Issues Explained
Q: Some users have noticed “bulging” and “patina” on display car seats in stores. What’s the situation?
A: Xiaomi SU7 display car seats use Nappa genuine leather, a natural material with inherent characteristics. Prolonged pressure can stretch the leather’s internal fiber structure, requiring “rest time” to gradually restore tightness after pressure is relieved.
During the initial launch period, high foot traffic caused continuous seat compression without adequate recovery time, leading to minor surface deformation. However, the seats will naturally regain tightness over time. Production vehicles additionally feature high-density composite foam beneath the Nappa leather to enhance rebound performance.
The so-called “patina” refers to surface stains from thousands of daily uses without timely cleaning. Xiaomi SU7 leather seats have stain-resistant treatment – specialized cleaners can restore them to like-new condition.
The seat assembly passed rigorous testing, including 25,000 entry/exit durability cycles (exceeding the 15,000-cycle industry standard QCT 740), and is covered by the vehicle warranty.
