I was looking at the 2007 CLK63 on ebay and noticed a lot more bolster in the new models, plus they seem to look a bit less bulky than the rather large seats in the W208.

Has anyone attempted a retrofit of these or any other seats from another mercedes model? I feel like I have two mattresses in my car right now.

These are the seats: http://images2.auction123.com/sizequ....jpg?web001lnw

They are still a little bulky on top, but the bottom looks very supportive.

 

i dont see why this cant be done at all all you need is accurate measurements of the rack of those seats and could make for a greater diy project
