Definitely awesome. You don't even KNOW how hot your ass is until you flip the switch sometimes.
When it's humid, you'll wish you had ventilated seats.

Haven't had a lot of experience with these -
A friends S4 I drove had impressive seat cooling. Like WOOOOOSH - things are all good - kinda cooling.
Drove a Lexus GX460 and I could notice some cooling but not like the Audi's.
Any manufacturers out there leaders in stopping the swamp seat?
I went from 0 of my cars having ventilated seats for 22 yrs in the Carolinas to now 2 cars having them (both which work very well), and it's a night and day difference in driving comfort. Totally worth it. If I had to buy a new car and cooled seats was a $1K+ standalone option...I wouldn't even blink.
I've had cars with and without them. When the seats are hot they blow hot air, rendering them kind of useless. I've found it's better to get light interior/exterior colors and tinted windows. If they were actually cooled with refrigerant I think they'd be worth it but personally I wouldn't let them sway purchasing decisions.
Bought the wife a Subaru Ascent with ventilated seats back in September when it was still 100F outside here. Can confirm that they are really nice in hot/humid climates, and never felt like they were just blowing hot air (even though I believe the Ascent's seats are just ventilated, not actively cooled). It's a feature that should be offered more widely.
