Some of you may remember my threads about the 2012 MB C250 that I have been trying to help a friend sell. The driver seat bottom had a tear in the MB Tex material, and the tear was in the seam. Some people found this to be a deal breaker so I decided to replace the cover. MSRP for the cover from MB is $332 and the cost from an online MB dealer is in the $230 range. A local upholstery shop quoted $450 to repair the existing cover. So, the decision was easy - replace the cover myself. Surprisingly, this cover is not attached using hog rings. The perimeter of the cover has a "snap in" plastic channel. Each "fold" has 3 plastic clips on the cushion side which clip onto a metal rod that is built into the seat cover. I think the clips hold the material so tightly that overtime, the material will tear. The bottom seat cushion assembly is attached to the seat frame using two T30 bolts. The seat doesn't have to be removed from the car. In total, the entire job took under an hour. This is a good thing since they supposedly tear very often. MB made it very easy to replace the bottom seat cover; I just wished it lasted a bit longer.
