M3 Seats Uncomfortable?

haven't had the opportunity to sit in a M seat without all the adjustsments (side, lumbar) but they are by far the best seats i've sat in. i've owned 3 e46's and 1 e90, all had sport seats and every time i sit down in the seat, i remember why i don't want any other car. the side bolsters are just wide enough and the side supports for your thighs hold me in tightly.

one of the things i was very disappointed in when i bought my 335 was the lack of support in the seats compared to my e46. the inflatable pillow in the side bolsters is pathetic. i'm 5'3", weigh 150 lbs and am decently stocky and when i hit corners in my e90, i would slide right out of the supports, whereas in my e46 the side bolsters just hold you in. go look at pictures of the 2 seats, the e46 side bolster is enormous compared to the e90. also, the side thigh supports are bigger in the e46 versus the e90. all little things but go sit in both back to back and tell me which holds you tighter. i recently went to a dealership and sat in a used e90 and i got out about 5 seconds later thinking "yep, that's why i drive an e46".

the e90 seats are ok and i'm not a big guy but if i was any bigger, i'd be sitting on top of the bolsters, not being held in by them. that right there is the difference between the e90 and e46.

Took a road trip from Salem (Oregon) to Las Vegas, I personally never found the seats to be uncomfortable during that trip or any of the daily driving that I did with the car.. Have the full adjustable seats with the side bolster inflate/deflate switch and I also found that the lower leg extender was quite nice to change the pressure that was applied to the back of my legs.
