I just bought a 2007 4r sr5. I love everything about the truck except for the drivers seat. It is a manual adjust seat and it's about the most uncomfortable seat I've ever sat in. I am 6'3" and 200lbs and I can't get comfy in it. It is beyond stiff and I actually get a sore neck and shoulders after a day of driving. The fabric is beginning to pull away where the seat and the back meet. Has anyone experienced similar issues?
