In the 2nd row of seats of a Sienna Limited Toyota how do you lay the seat back flat on the seat?

To lay the second-row seats of a Toyota Sienna Limited flat, locate the release lever or button on the side of the seat. Pull the lever or press the button while gently pushing the seatback forward until it is flat. Ensure the headrests are lowered to create a more level surface. Repeat this process for the other seat if necessary.
