Mercedes® Sedan/Wagon Backrest Cushion, MB-Tex, 1977-1985 (123)

Do you get a sinking feeling every time you sit in your Mercedes? Better check out the seat pads and seat springs. The seat pads are made from a foam rubber-horse hair type material that deteriorates over time. One way to check if the seat pads are bad is to look underneath the seat, if you can see bits and chunks of the padding, it's definitely time to replace the pads.
