I'm not exaggerating when i say i feel noticeable warmth in under 60 seconds. By the time i've backed out of my driveway, the cushion is toasty. This is a massive improvement over old-school "hot wire" cushions that took ages. Even heating: the warmth is perfectly distributed. You don't get those weird, uncomfortable "hot stripes" or cold spots. It's just a consistent, pleasant warmth across the entire seat and lower back. The plush material itself is quite comfortable, and the cushion adds a bit of padding that's nice on my long commute. The high setting gets very warm (perfect for sub-zero days), and the low setting is great for just taking the chill off.

It was well cultivated.
