I'm 6'-2" 210lbs. My back is all jacked up and the stock seats are the only ones I can sit in for long periods of time. I love them. I can't even sit in my lexus for a long time and they're made for comfort.

 

I'm 5'10" 150lbs. I go to the chiropractor regularly too. IMO the stock seats don't have enough lumbar support. My friend's 15,000 mile cloth seats feel more supportive than my 30,000 mile leather ones do. Maybe mine are just broke in more.

 

these are the 2nd most comfortable seats i've sat in (#1 for lumbar support tho). My 745Li was just so comfy esp due to the ride quality on that car. The seats are like 19way adjustable or something with massage/heated/AC seats. God i miss that boat

 

I'd love to have the massage in my EVO. That would be great, especially if it had the happy ending button.
How are the seats in your turbo'd phantom?
