2003 Highlander Power Seat

Is there a way to raise the front of the driver's seat cuhsion higher that it currently goes on my 2003 Highlander. I have a driver power seat, but even at its maximum height adjustment the front edge of the seat is still too low. At the maximun adjustment downward, the front engde of the seat so low that I a am almost sliding onto the floor. Is there a mechanical adjustment to the seat assembly or the seat track that will solve my issue?

Thank you,

Logan
