Interesting idea of creating my own personalized cushions.
Is there a shop around that does that?
Of course a problem may be that since my back is already bad, creating an "imprint" of my bad back may not be helpful at all!
This is a standard process for making seats in race cars. You purchase or build a simple seat shell ( like the Kirkey seats without the covers on them ) and sit in it while someone pours two part expanding foam into a trash bag behind you. When it's done the foam has solidified and you pull the foam out of the trash bags, shave it, and then put fabric over it.

It's really fun and not terribly expensive. You can also repeat the process as many times as you want until you get the cushions that feel right. After the foam has hardened it can still be supplemented with hand cut self adhesive memory foam sections if you find you need a little more support in a specific place.

During the few minutes that the foam is setting you would need to maintain good posture. If you can't do that you can find someone approximately your height, weight, and proportions to do it. This is where you can avoid making a "bad imprint".

I don't know how you can accomplish this with a seat that has a hinge in the middle so I'm afraid I'm no help there but you could leave the reclining passengers seat in the car in order to get rear seat access even with the fixed back drivers seat.

I recommend wearing a driving suit when creating the expanding foam seat mold. It gets rather warm/hot when the chemical reaction is going on. Fun though!

Thanks Chris & Dave.

Out of curiosity, is there a local shop that does this?

Reality is that it has been recommended to me by the docs and PT's to avoid fixed back seats because having the ability to change sitting positions is crucial especially on longer drives.

So.... Is there a local shop that specializes in sport and racing seats?
Someplace that has various seats to sit in and someplace that can help with fitment, ergonomics and installation?

Honestly, that sounds like a tall order, if on a budget. You may need to just bite the bullet and go with a high quality unit. I would contact a couple of high end race shops near you and start discussing your options. I'd love to know what they say. If they know your budget they can likely recommend something, or someone to help you find what you need.

Thanks Mike.

So, you guys have any recommendations for race shops here in the bay area?
I'd guess that GrantK would have some thoughts on the subject. Grant?
