A couple of seat related questions....

I was wondering what the orthopedic seats were like that were available on the W123's as an option. I also noticed that there was an option for reinforced seat bottoms as well.
Anyone know more about them?

Dont know much about them technically, but as far as comfort goes, they are exemplary. My father had a 190D 2.7 years ago that had them. They seemed to be highly sprung, but more on the firm side as far as support goes. They blocked out alot of the ride inconsistencies, had ample lumbar support, and they almost seemed to mold to the shape of your back, supporting in all the right spots.

Id actually be interested in retro-fitting them on my 300DT when I prepare to re-upholster my seats and re-spring them.

I guess I'd be interested in getting a set for my '85 300D as my original seats are very uncomfortable for any long drives. There are absolutely no rips or tears in my seats but the drivers side seat bottom feels like the left front corner is broken or something as it does seem to have as much support as the other corner. Funny thing though I don't remember what sitting on the right side is like because I've only been a passenger in it once and that was to let my wife drive it.

My driver's seat has collasped completely.. the raised columns in the leather are virtually flat...guess the felt inlays have deteriated with the seat pad..

Are your springs squeeky? Mine sure are.. Did I read or dream that MB fixed the noise problem with the springs?

My seat springs don't seem to be that squeeky but the plastic trim pads sure make a lot of squeeking noises when the interior is cold. My interior is in surprisingly great condition considering that it has over 225K miles on it. That's a lot of time spent sitting on the seats. BTW I have M-B Tex in mine.

Here are a few tips to homebrew seat rebuilding:
1. Remove seat, separate into bottom and back
2. Remove seat slider adjustment assemblies.
3. Clip hogrings retaining the seat cover on seat bottom and peel off.
4. Inspect spring frame for broken springs/wires. Replace spring frame (seat pan) or repair. Repair can be done with same gauge or heavier wire looped/tied, etc. to hold the broken sections together. Make sure cut ends point DOWN or you'll get a surprise when you sit in it. Pool noodles cut to 3/4 the length of the front coil springs in the spring frame and twisted into the springs really firm up the seat.
5. Inspect foam or horsehair pad. Sometimes the spring has "eaten" or cut into the foam causing it to lean to one side. A piece of industrial carpet, like office carpet, tied to the top of the seat frame with mild steel wire will keep this from happening. You can also build up flattened pads with pieces of foam sleeping bag pads (the cheap closed-cell type) stuck in place with 3M spray adhesive. Strips of the foam can also be threaded into the "raised inlays" to replace of restore them.
6. Reassemble by flipping over seat bottom and kneeling on it to compress the padding/springs so you can pull the cover into position and reattach it with either hog rings and a hogring pliers (Upolstery shop) or small pieces of 1/16" mild steel wire in the same locations as tthe originials.
7. Lumber support in seat back can be improved by installing pieces of sleeping bag pads with spray adhesive in the areas you need them. I try to cut the size/shape I want and try it out before I take the seat apart.
This is a whole lot cheaper than buying new parts or paying someone to do it. RT

I did the pool noodle & carpet trick on the 420SEL a couple of weeks ago. Made a world of difference. Did not have to separate the back from the bottom, or remove the track assembly.
Simply pulled the cover off the the front of the seat bottoms and peeled the cover and pad back to expose the springs.
Leave the pool noodles about twice the length of the springs, then cut them off flush. It makes twisting them in so much easier.

Took about 2.5 - 3 hours for both seats.

Time well invested.

What are pool noodles? Do you have a photo of them?

Great Advice RT.. I;ll try the molded foam on the seat back when I get around to that project and report back...

lietuviai,

Those pool noodles are a sort of poly-foam product about 3.5" in diameter and about 6' long. As the name implies they are used as flotation devices in pools. Popular with kids and are found at Wally World in spring and summer.

I should've known that that's all they are.
