Just created an account here to share the mystery of uncomfortable seat in Tesla
After getting no help from Tesla for 6 month I went to Uphostery Shop and asked for their help.
Here is what I can tell you. Tesla workers who designed the seat should be fired for such a bad design. The cause of the pain you are guys having is a direct result from a bad frame seat design. It should be a crime to make people suffer like that
here is the Tesla frame. Sorry but in that picture the depth is not very visible, but there is deepening hole where the springs are, that is why bigger people just sink into that hole and the thighs/butt are starting to push hard against that frame part that causing the pain

And this is how any other normal seat deigned (the guy in the shop was kind enough to show me), almost flat design, so there is no chance to sink down, because the frame is flat

Here is the original foam

The upholstery shop needed to add 1.5 inch foam in order to even up the bottom cushion so the butt will not sink down.

No more pain! but Tesla seriously needs to learn some basics of seat making and take the responsibility for what they are done and offer that fix to people who are in pain
here is the shop I used (costed me $200 +tax), very nice people
