too lazy to condition the leather once a week, but every time you park the car you deflate your bolsters? Seems a bit off haha
But when I first got my e90 I was religious in cleaning the seats once a week, but my old habbits (or lack there of) kicked in and I clean them maybe once a month. If you're that worried, just do your seat and maybe the passenger seat. If you're like me, the back seats don't see too much use.
