2013 sonata car cloth seat issue

Hi I purchased a Hyundai Sonata 2013 2 weeks ago and i am really pleased with the vehicle. I just have a question about the cloth seating. Is it me or do the sides of the front seats seem not very firm or strong like other cars. I sit down to drive and i have some creases along the sides of the drive seat where the edges of the seat curve up. Its noticable and then the next day it doesn't look as bad but still kinda there. Im a big guy so I know ill probably put ware on the seats but i dunno.

Is this normal? cheap material? or am i just knit picking?
