My son has a Bolt and has no problem with the seats. I have ridden it many times and the seats are no problem. The seat "issue" is blown out of proportion. Unless (unlikely) they are making these cars differently, I don't understand why most people would. There are always a few exceptions...
I've been following this issue as I've considered leasing a Bolt. The seat problem has too or even three components:
* Seat design. The seats are too narrow for larger people who are used to seats that fit them. This is present in all the cars, but doesn't affect all people.
* Seat production defects. The padding in many - but NOT all - of the seats is inadequate. Since the padding is preformed, it's apparently a problem with some of the padding units being either too thin or too soft. Some of the seats have the wrong size (too long) bolt in a critical spot right under the padding where the driver's left thigh rests. Or they may all have it, but it only impinges on the thigh in seats where to padding is also inadequate - I'm not clear on that.
I sat in two Bolts last Winter. Neither had immediately perceptible padding issues (although my left thigh was less comfortable in one of them), but then it often only becomes a problem on longer drives, which I didn't take. Both of the seats felt too narrow for me to be truly comfortable. Lots of people get a Bolt that they find to be perfectly comfortable. Quite a few (like me) find the Bolt to be noticeably less comfortable than the Leaf and similar EVs, and a few people just can't stand to sit in their seats for longer than 10 minutes.
