Going to try it... my leather is good but seat feels a little flat so instead of trying to find a Sport seat I ordered the foam for the lower half of the driver's seat.

Part #124 910 23 50 in case anyone is interested.

I'll take photos.

Read on another site foam blocks available for more support:

Part #124 910 16 75

Trying to verify that.

I believe your seats already contain those foam supports. It's the early models that can benefit, since they lacked those features.

You might want to get a new spring box too, they are known to collapse after time and are probably the main cause of the problem.

Thanks. My seat may only need a foam replacement.

Do you have to go through all this just to change the seat bottom foam?

Yes.

Think carefully about just replacing the pad, it may be false economy.
You can buy a heavy duty spring box from MB now, seems they have understood the need to offer a solution to the collapsed box syndrome.

$297 for a new spring vs. $91 for a pad. The spring could be bad but I have to wait until I get the seat open to know at which point I can make a decision.

But foam vs. springs... think foam. My passenger seat is much more "foamy" feeling than the driver's side... that's without sitting on them just pressing them with my hand.

Are they still making seat pads out of "sea foam"?

When I had disassembled my seats for a similar sagging issue, the seaweed pad appeared fine. So I went to Home Depot and purchased some firm (but not hard) rubber blocks which I shaped and interspersed amongst the springs. Made a world of difference for only a couple bucks.

While doing that, you can also buy some firm foam pipe insulation, and place in the lumbar area of the seat back. Also well worth the time.

How much was the foam part? Aren't they originally horsehair?

chabanais, was was the final result of your project? Did you use the new pad on the old springs, and if so, did it fix the problem? I'm having a similar issue with my new wagon...

:crying
Ha I haven't done anything! Still have the damn spring base and pad in the garage. But I'll update the thread when I get 'er done... probably in the next few months.

Wasn't there an article on beefing up the seats with swimming "noodles"? As I vaguely remember they were bent in a square "u" shape. And yes, I would have no qualms at replacing the springs. That is probably the real problem.
