It is actually a little more complex. There are three types of headrests that can be on a W221 S-Class. The first is the standard one-piece headrest. (I agree they are ugly). These can be found on early build S550s. Any S550 that is being sold now should have the two piece headrest. The purpose of the two piece is that the headrests are "active" in that in a rear collision they come forward to help protect your head from whiplash. The last type is the two piece "luxury" headrest that is standard on both the S600 and S65 AMG. These have the rear collision safety feature as well, but also there are more adjudstments for comfort. I don't know how they adjust though...maybe there are S600 or S65 owners that can comment?
