Surprisingly, I found the civic with fabric seats (mine) to be more comfortable than the one with leather seats (my brother's car). A lot more cushioning and comfort in non leather version. In fact, even when I got the seats leather wrapped, they maintained superior comfort over the factory leather seats. This was with reference to the 9th gen civic.
My boss has a prado 2010 with factory leather seats. The seats in my ex Surf 2003 (fabric, covered in leather locally) were more comfortable for him than in his prado. In fact, he asked me if I had added some cushioning in the seats when he hitched a ride with me.
Are the seats in your civic oem leather or fabric?
