Any way to adjust spring tension on the seat?
 

My seat seems to be too hard. I don't think my '88 300CE was this hard. My legs at the buttocks get numb. Wondered if there's some way to adjust the springs underneath to make them softer?

Maybe the seat pad is worn out. Check www.worlduph.com for replacement pads. Rather than spend on replacement pads, I added patio chair foam between the pad and the upholstery.

Sixto
... stay tuned

My 82 300sd had a bad seat. I found a new spring and pad on ebay. Holy cow, what a difference. Very firm and comforable.

Been watching ebay for another set for my 87 sel.

It IS worth the money to buy these two items

Springs are TOO tight
 

Oh, I'm sure my springs are just fine. The seat is comfy for a short trip, but seems it should be a bit softer. The problem is, the springs are TOO tight. A weaker spring would be good!

MB designs their seats to be more taut than the typical foam seats. I think you will find it difficult to weaken the springs. A more common complaint is the weakening of the seat box springs at the driver outboard side in the front.

Every MB I have owned has that problem. MB actually offers a custom foam piece to firm up that side. I know it exists for the W124 model.

I had a '90 300E. I bought a new seat box and pad, which, when installed, firmed up the seat bringing it back to new. Then I traded for my '92 Sportline with the Recaro seating. For the first month I seriously considered selling the interior and replacing with standard W124 seats. Then my body grew accustomed to the firmer seats with stiff side bolstering. I have driven that car over 143K miles mostly very long interstate traveling. Suits me fine.

Maybe you could just buy one of those memory foam car seat cushions you can find on the internet.
