seat lumbar support suggestions

I too am finding a tough time getting 100% comfortable in the seat for longer durations. Not sure if it's that the cushioning isn't broken in yet (if that's a thing), that I'm a bigger guy @ 245 lbs, or if it's residual back issue from my car accident in Oct that wrote off my last 3 (rear ended pretty damn good on the hwy). That was a 2010 GT with no adjustable lumbar support, but had memory seat which was amazing, and I could go for hrs in that thing.

I find myself fiddling with the seat here and there still after a little over 3 months and 11,000 kms - it's my only real issue with the car.

Hasn't been bad enough that I've wanted to buy a support or anything but if there's something that works, especially one that will go inside the seat, i may be interested in getting it installed.

Unfortunately there's no memory seat like my 10 had, so as soon as I think I get it damn close to just right and I need to fold the rear seat down I have to move my seat position because the back seat won't fold flat with where I had it set and it takes me forever to get it back close to where it was.

I've made 3 adjustments to my seat and my regular daily commute (1+ hrs each way) has become much more comfortable in the un-modified seat. After reading around I did the following:

- raised the seat as high as I could - a fist worth of space between my head and the headliner
- tilted the seat back more upright
- reduced the lumbar support adjustment
- also pulled the steering wheel closer to my body so I wasn't reaching for the top of the wheel.

Although it now feels like I'm a tad close to the wheel compared to what I'm used to I am now much more comfortable both upper and lower body. The only downside is my left arm no longer reaches the armrest on the door even when fully relaxed (I have short T-Rex arms). However left elbow on the window edge and hand-to wheel is much more comfortable.

At this point I actually haven't touched the seat controls since before the drive home Monday afternoon, whereas prior to that I was fiddling with them at least once a day.

With all that said I still intend to install that electric air bladder lumbar support I ordered - I can't cancel it anyways as it's already been shipped. Although I am now much more comfortable than before I feel the OEM lumbar adjustment just isn't in the exact right spot for me and if this kit offers me greater flexibility and customization it can only be a good thing for me.

Having the seat foam modified was not an option for me. I want it adjustable in case my needs change down the road or my wife needs to drive the car so she can make it comfortable for herself.

It took me about 3 months to get comfortable in my car whereas it normally only takes about 1 month for me in a new car.

What I eventually figured out by getting out of the car and kneeling down right next to the seat and then adjusting it and closely watching the seat movement as I made different adjustments was that the seat height adjuster also moves you incrementally closer to the steering wheel as you raise the height. So if you get the fore/aft distance right and then adjust the height after that it changes the fore/aft distance slightly, just enough to throw you off as you think the fore/aft is set right and then as you drive it feels off because the height has changed this distance. I've never seen this before but I think this may be the reason some people find it hard to get comfortable in these seats.

Once you are aware of this behaviour it makes it easier to adjust accordingly. In a roundabout way this is actually a benefit as it allows you to make smaller fore/aft adjustments by using the height adjuster, raise it one or two settings to move closer and lower to move further away without having to use the seat slider adjustment.

I am aware. It's due to the linkage in the seats for the adjustments. Rake of the seat back does the same.

For these reasons I adjust in this order:
- Seat height
- Seat back rake
- Seat position fore / aft
- Steering column (for arms / reach)

Of course there's always little tweaks here and there in the process, but that's the main order I aim for.

And as a follow up I have been MUCH more comfortable in the car since my last post about seemingly finding my sweet spot. I haven't touched it since and discomfort / lower body pain on a daily basis is gone.

No multi-hr drives to really test it since then, but I've been in the car for 3+ hrs in a day and have been good.
