I forget the weight, but the seats themselves are fairly light considering they are leather. The carbon fiber backs I'm sure helps offset the leather a little. The sliders and brackets are what weigh so much. When comparing weights between the factory seats the Misanos complete with sliders and brackets they were a few pounds lighter than the manual passenger seat. So on the power drivers probably like 30 lbs lighter or so.Those are some NICE seats! How much do they weigh?
