I think they actually suck the air through the pores on the seat and push it under the seat, creating a cooling effect.

 

On my Lexus NX450h+ the conditioned, cool cabin air only blows through the seat back and the seat warmer only heats the seat bottom.

 

So today I went to the local landfill. AC was on. Left the car "running", READY mode, as the MRS was with me. Nothing but the best road trips for her.

After I ditched the junk, I stepped back into my car and immediately noticed how cool the seat bottom was. I had shorts on.

When we first got our first car with ventilated seats, we noticed the cool air and it gave us a feeling of having peed our pants (). So I guess if you're in the car while it's operating, your body doesn't notice how cool your but is as it gets cooled over time. I suggest, just to convince yourself that the seats do indeed cool, make a dump run and observe your butt temp when you get back in.

All tongue in cheek of course!

 

Compared to the cooled seats I had in my F150, the cooled or ventilated seats on the Lexus is a joke.

 

On my 2012 Lexus ISF I had a 3D printed plastic A/C duct. It took the air from the rear seat center console. Directed down and to the bottom of the driver seat. Then pointed it up

I bought it from someone on ClubLexus about 8 years ago. I looked all over for the ad or posting. But couldn't find it

The closest I could find was on Etsy. It worked great when I lived in the Mojave desert

I would go as far as technically calling that a trip to the dump is 'a date' after 30 years of marriage! Just don't let my wife know .
