I dunno about 'best all time' but the stock seat (split bench) in my '92 Dakota is pretty comfortable to me, that point was driven home today when I drove my Wife's Kia Soul up to Houston.

I didn't feel sore while I was driving, but, DANG, I almost fell face first when I tried to climb out because I was so stiff and my tailbone hurt so bad.

Part of the comfort with my Dakota is that the armrest fall where they actually work. Not so on the KIA.
