I bought a 2006 LX, which has leather seats. I found them uncomfortable from day 1 after 15-20 minutes of driving. I tried every adjustmet possible but it just doesn't get much better. My complaint is a achiness in my back thighs. I was on a business trip and was offered a sonata to rent. I figured what the heck. It was a 2006 GX V6 with cloth seaths. I found these to be more comfortable (more in line with my previous car), and did not suffer from the aches. I know the LX is supposed to have "better" seats, but this is one area that is subjective and depends on individual body contour. But will the lx seats "break in" (the rental had 9k miles), or will I be facing this forever? Are the cushions of the LX and GX the same? or is it the wrapping that is making the LX seats appear harder? Thanks
