I had replaced both bottom and back with OEM Lexus seat foam along with aftermarket heaters when I first recovered them with the LSeat leather. That was about 10 years ago.Jon,
You deserve to brag! Nice job. What did you do about seat foam? I now have a July 1 deadline in front of me and need to get busy.....finishing steering knuckle today hopefully!
Thanks for photos.
I'm not certain about this, but it sure feels like the Katzkin installer added some supplementary foam when they installed them. I'm sitting higher than before, and the back bolsters feel firmer.
In short, they're very comfortable and I'm a pretty happy camper.
