For those of you that have leather seats...

Is your seat (not the seat bak) leather tight or are you starting or have wrinkles on the seat bottom...kind of toward the rear of the seat - they would be fine wrinkles near the seams or edges.... or is your seat still stretched tight without any wrinkles... I've got them and I've heard that's normal and I also have heard that it's supposed to remain tight without wrinkles.... I'll try to post pictures later today if I need too....just wanted to see what people thought.... Thanks
