Looking for advice on seat modification for lower back pain

[chumpygrumps]

Hello all - I know most people find the F-150 seats somewhere between comfortable and extremely comfortable. Unfortunately, I'm in the small set of people where the exact shape of the seat causes me lower back pain (2022 XLT 302A, PB, FX4). I had a similar issue with a Toyota Tacoma a number of years ago. I'm wondering if anyone on the forum has themselves or through a vehicle upholstery company to improve the seat comfort.

To give more detail on my issue, there are a couple areas:

• First, the bolsters on the bottom cushion are so high and firm that they press against my hips, activating my sciatica. I took the cushion cover off and trimmed down the bolstering near the rear of the seat and that issue is resolved.
• Second, the angle of the seat cushions where the bottom cushion means the back creates a cavity that I believe causes my hips to tilt too much, which compresses nerves, overextends muscles, etc. I can hold a position that I can tell is "better", but holding it against gravity causes my back muscles to get sore, after only 15 minutes in the seat. I have tried adjusting the lumbar support - but it is too high to be useful for this specific issue (8-way adjustable seats, so I cannot move up/down). I have looked at my other vehicles that are comfortable for me, and in those the back of the seat cushion raises higher, and in the F-150 it is slopes down, and I believe this to be related to the root of my issue.

I have seen on other forums that people have experienced this since the MY 15 onwards, even in some cases before, and all those threads are 90% "but the seats are comfortable for me!" and not a lot of solutions. Does anyone have experience with this in the 2021/2022 MY F-150? I'm iterating through different cushions to help, but looking for any concrete experience solving this kind of problem for anyone.

I would suggest before making major changes to get some other cushions or lumbar support pads to try different things. I would hate to do something expensive then figure out I made my problem worse
