I use the pad in my BMW on beige leather seats. For me the pad fits perfectly. It is somewhat thicker and has a good feel. The backrest is padded breathable and super. Recesses are on the sides of the Isofix attachment. The installation is very simple: Seat besfestiggen it and by belt to the headrest. Feritg. I could not detect any odor while unpacking.
Conclusion: A bit more expensive, but the price is justified by a good workmanship and good feel. I would buy again.
