The seats in the Prius are very comfortable. Lumbar support is sufficient, but not adjustable. Neither is seat height. I would like both of those features, even if they were not electric but mechanical, however that isn’t offered.

But I have found the seats to be very comfortable on longer drives. The fixed lumbar seems to be in the correct position and the correct firmness to be comfortable but not annoying. The cushions are firm, but supportive. The back seat is also very nice and comfortable, if that means anything to you.
