It's only been a day, but I can already say that the new Model Y Performance has the most comfortable seats of any Tesla that I've ever experienced. • The powered thigh extenders are great for comfort on longer drives, or for taller people who want extra leg support. • The bottom seat cushion has less aggressive bolstering than the Model 3 Performance seats, making it easier to get in and out of the vehicle. And if you're a bigger individual, the cushion won't hug your legs too tightly. • The side bolstering on the back seat cushion hugs you perfectly and is amazing. I wish I had this in my Model Y Premium AWD.
