Pretty hard to build a seat that firs every different shape of mankind. (Although Volvos are close).
For every one complaint here there are likely more than ten times that amount that don’t have an issue.
Unless one can feel, with their hands, lumps or ridges, actual deformities in the seat, it's the seater(?) The seat should be supporting the entire contact area, the pressure uniformly distributed, not just the sit bones or hips. It will otherwise feel like lumps at the higher pressure areas, ie, the sit bones. If, after trying the adjustments in the manual, it has not improved, go back to the dealer and driver another of the same model and trim level. Feel the same,? have the dealer go thru the driver seat adjustments with you. Yes, I know, you've driven cars for x number of years, you don't need no instructions! Me too, 60 years+, until I followed the instructions, ...the ones in the manual...my butt and back stubbornly refused to "get used to it".
