Ive never had heated/cooled seats before the Murano. So its still a bit of a novelty to me, and I didnt really know what to expect. But it did indeed cool and heat. Its not super aggressive, but it works well enough that it keeps the leather from feeling too hot, and warms up my back well enough that I can use it to relieve my sore back on the drive home from work. Could it be better? Yeah, probably.
