I've driven dozens of recent model media vehicles, almost always loaded. Seat heaters and ventilation/cooling vary a lot. Some actively cool almost the entire surface. The R4P system is one of the weakest I've encountered. Better than unventilated black pleather for sure but not competitive with some other systems. They are not cooled direct by the A/C system like some other vehicles that can really conduct the heat away from you and precool the seats as well. They are only ventilated, presumably for efficiency, and they do not turn on with the app, at least they didn't before my trial ended. They blow cabin temp air, so you can't run just seat ventilators on a hot day with the windows down and expect them to keep it cool like you can on some other vehicles. Plus, it only blows air at the thighs and mid back, not at your butt or lower back. It's OK if you have the windows up and A/C on. If you leave off eco drive and climate modes, the ventilator fan will blow a little faster at max speed as per manual. The seat heaters are equally weak. Max setting is about the same as the lowest setting on our Honda Insight, for example. Still nice in the winter but they can take a very long time to manage luke warm when it's really cold.
Cloth seats vary widely, too. Depends a lot on the material, weave and color. Our Highlander Hybrid fabric was pretty good. I've been in other vehicles that are no better than perforated pleather. Niro comes to mind offhand.
