With a statement like this, it really helps to state what seat revisions you have:
- 1.0, the original seats from 2012 and 2013 with vertical stitching down the middle of the back
- 1.1, the original seats + a spring TSB to have more give in the seat
- 1.5, the 2014 and onward "standard" seats with the taller and closer to your neck headrests and deeper thicker cushions than 1.1
- 2.0, the 2014 and onward "next gen" seats made by Recaro that have horizontal stitching on the back and serious side-bolstering
Generalizing, comfort has been said to get better with each revision, but my 1.1s are very comfortable and not troublesome at all after a 400 mile road trip. The 1.5s in the loaner I drove had thicker cushions, but felt just as comfortable for my workday commute. They works great in launches (my test drives also had 1.5s).
What is "a spring TSB". I have 1.0 or 1.1 and would like to know how to tell the difference (car delivered early March 2013). The loaner with 1.5's I had were terrible, the neck rest was way to low in and I could not adjust the seat for comfort. I could not have gotten the car if I had to live with the 1.5's and the neck rest issue.
