OK you win, but I was close. I`ll start taking notes on which one`s I come across that have the fixed seats. From what I remember seeing, I thought it was the Turbo Diesels that had the adjustments.

I know my cheap azz 80 240 "had" the fixed seat.

Hey Jooseppi, nice work. Reason the seat skin came apart so easy is probably because I had the seat apart to replace the seat foam and spring which was sagging to one side badly. The PO must have been very heavy. The parts came from a 240D seat Jim Smith gave me. Have fun!

The coils in the front corners of the seat were an attempt to alleviate the broken sagging springs of the earlier 123 seats. They provide more support for the seat in the corners. They were not entirely successful and I believe MB has an actual pool noodle as an official part for installation inside those coils to provide yet more support.

Nice kitty by the way.

I just got done rebuilding the front seats from a 1979 240D. BOTH seats had fore/aft adjustment as well as height adjustment.

Here is a thread from back in 07 about firming up the W123 seat corners

Interesting, maybe all the early w123 seats had them.

I rebuilt both front seats in my 84 & 85 300D. I posted photos in another post. I also unbolted the bottom from top, and didn't fool with the top in both cars. My main additions are that I tied the top wires together with either "rebar tie wire" or a net of 1/4" poly rope, covered w/ spiked carpet runner, then a layer of thick rubber foam (garage shelf liner at 99c Store). The 85 had horsehair, which was more degraded, so covered the top w/ thick burlap. I hog-ringed the carpet runner and burlap to the steel frame. I glued the felt runners back to the seat covers. I repair broken springs by inserting the ends into 1/4" copper tubing w/ epoxy and crimping. I spent more time freeing up and lubing the seat tracks. I used harsh-weather bicycle chain lube since it is supposed to stay put and handle dirt. For the finale, I use sheepskin covers which feel fantastic.

I wanted to thank Jooseppi for this, I'll be rebuilding my seats at some point and will find it very useful. Looking forward to the rest.

So you're saying that later w123 300 models had non-adjustable "fixed" height? And when you state that "early w123 300 had an elevation adjustment on the passenger side" is there some actual authoritative info for that or is is just an opinion?

"Mercedes Option Code # 572 Vordersitz rechts mit Sitzhoehenverstellung - Right Front Sear with Height Adjuster"

Suggests that the Front Passenger(Right) seat was standard without height adjustment and that height adjustment was an extra option.

What options were included depended on who was ordering the vehicle, in the US often times it was the dealership in consultation with MBUSA, that's why most US vehicles had auto transmissions, the dealership and MBUSA decided based on their market research that US customers preferred automatics. It's likely that they specified the #572 option as most of the w123 300s I've ever seen have front Passenger height adjustment, in fact I can't recall ever seeing a w123 300 without it, except for Euro/Gray market cars. I suppose some US based customer could have ordered a car without the #572 option, but I doubt too many people would have passed up buying a car with that option just to order one without it.

Does the Data Card for your car list option Code # 572, that's the code for front passenger seat height adjustment?

Couldn't say. I junked the rotted shell of that car a few months ago. I saved the seats for rebuild and use in my '83.

Hi Jooseppi Luna,

Thank you so much for this! I'm currently restoring my 1985 w123 and at some point, i need to replace the upholstery as well. I was wondering whether you already finished the project. Is it hard to instal the new upholstery? Or is that the reverse? Is it easy to put the edges of the upholstery back to where they belong?

Thanks again!

Thanks for all the great upholstery info! My husband and I are working on a complete restoration of an '81 300TD.

Does anyone know if the seats are interchangeable from '85 300CD to an '82 300TD? I have a coupe that we're taking some parts off of and the seats are in much better shape. Would love to swap them to the wagon but they seem slightly different.

The seat upholstery is the same with the exception being the seat back release button hole in the coupe. The seat base is interchangeable on the TD, D, CD etc. The seat base (spring box) should be different in the coupe because of the seat back being hinged. If you are putting seat back skins from a D or TD in a CD, no problem. The other way around, you will have a hole in the vinyl where the seat back release was. You could just install the release button in your TD seat back to cover the hole, but it would not be hooked up to anything.....Rich
