Please find these numbers and share as I am just getting ready to do my first seat -thanks!

Please share. My car has them, but they're getting a bit tired. EPC says it's not applicable to my model

I believe MB labeled the option as 'Front seats with reinforced frames' At least that is what my 1991 MB Sales Brochure shows.



Part number is: A - 126.914.22.15

They are about 5" tall and about 2" in diameter, in a dark grey color.



I will turn this thread on you guys now, anyone where where to order some of this high density foam?

Ok, looked on a euro 420SE. A1269142215, 2 per seat. Impex has them for $6/each.

Tidbit: Late W124 seats have large foam pads on each side, supporting 2 coil springs per side. W126 (and I assume w123?) seats have only one coil spring per side.

Does anyone have a photo of these cylinders? I took all my seats out last winter and stuffed them with pool noodles. I do think I have them too stiff though. I'm curious to see what the official method is to stiffen up the seats.

Early 123's did not have a coil spring at all. I found that out when I tried to repair my 240D's driver seat. it didn't have a coil spring in at all and was so badly broken i just threw it away and replaced it with one from a junkyard from a later car which did have the coils at each front corner. I still braced that with pool noodles though but thinking back to it in retrospect I went over the top and it was far too firm in the end. I have seen the parts kit offered by **************.com. I think I would now use that first and see how it works before going the pool noodle route again.

It's a small black cylinder that fits inside the coil spring.

A site called mercedes source.com offers a seat repair kit that might solve the problem. I have not personally used the seat repair kit for my 300D but have ordered several things from his site and have been impressed with their service. I just went to the site and searched seat repair to find the kit.

I've got an MB cushion pad for a W123 coupe in my stash of spares that consists of foam bonded to a sheet of what looks like Masonite. So for those considering the foam route, I'd suggest starting out with a composite sheet maybe 1/4 inch thick and then gluing the foam to that. You'd want to zip tie the board around the perimeter of the box spring to keep it from shifting about .

In the past, I've used the felt-like indoor-outdoor carpet found at Home-Depot or Lowes to line the seat-springs and keep them from wearing through the seat-padding.

An alternative to pool-noodles is the poly-foam (not rubber-foam) pipe insulation. You can put different diameters inside each other as needed, to adjust for thickness and firmness.
I recently did this on a 240D drivers seat where one of the outboard torsion-springs had snapped. The seat now feels balanced, instead of trying to dump me out of the car when I open the door!

I also used some steel brake tubing to secure the ends of that broken spring. It didn't restore the spring function, but it does keep the jagged ends from clicking, scraping and screeching against the seat-pan while I'm sitting there.

Happy Motoring, Mark
