uncomfortable drivers seat

Yea, I hate the seat. There's just not enough leg room for me.

If I understand this correctly, what is lacking is seat base cushion length - it's not long enough for the upper leg length of some of us.

I like the power-adjustable seat in our 2004 LE... except for this lack of length.

Is it just me or is the passenger seat longer in length than the driver's seat?

While the power-adjustable driver's seat and manual front passenger seat in our 2004 LE look the same, they're obviously different underneath, and I wouldn't be surprised if there is a bit of difference in the base cushion length. I have not really noticed this myself, and have not measured to confirm, but it's an interesting possibility.

I'm 5'10" and I also find the seat very comfortable...

I just did a wiki on average heights based on nationality and it shows the average Japanese man is 5'7" (5'2" for women) and average north american is 5'9"-5'10" (5'4-5'5" for woman). Just a suggestion that maybe there is an influence on design there...

The Sienna is specific to the North American market, but perhaps there is still some connection.

It makes sense that if the seat fits well for robaer and not for those of us a couple of inches taller, perhaps we're outside of the target range. That might be a significant miscalculation by Toyota.

Good theory, but average heights (and weights) are on their way up in many countries which we have thought of as having short (or small) people. A big issue for the Sumo wrestlers...

Well said!

Now... how do I adapt the environment under my rear end to have a longer cushion?
Actually, I'll just live with it, but I would interested to hear of any good ideas.

I have built seat mounting hardware for our race-prepared car, but I suggest caution in doing this, as substantial forces can exist in a crash situation, and the seat mounting is part of the system of restraints which holds the occupant for safety.
