Comfort and quality
Honest review: At first, these feel a little awkward when trying to get the right position so that you don't feel like you're being pushed up from the seat. I'm a short guy, so maybe that's why I needed more time to adjust to them pushing up on my lower back. However, the quality and materials are great. I would recommend them for aesthetic purposes, and comfort is there when you can adjust them to the right spot on the seat.
