May I ask how many KM yours has done? Leather will crack when it's dry, and someone sits/rubs on it. The dry leather isn't pliable, so it folds over and cracks. Keep the leather hydrated through the summer months is the best way to prevent this, with a water based (not silicone) cleaner or conditioner. 99% of modern leather will have a polyurethane top coating which products with silicone in them are not suitable for.
This is my drivers seat after 207,000km.
