How do I maintain the leather seats in my Nissan Qashqai?

I recently purchased a Nissan Qashqai with leather seats and I want to make sure I'm properly maintaining them. What products should I use and how often should I clean and condition the seats?

You can protect your leather seats by using a high-quality leather conditioner once every 3-4 months. Make sure to clean any spills immediately to prevent stains.
