How do you get a second row seat out of a Sienna if its stuck?

I have found that the seats come out easily but if they don't, it is because you have to move the front seats forward to allow the second row seat to fold forward a little more after you press the side lever to make it collapse and fold forward. After doing this, you should be able to lift the seat easily from the clamp bars on the floor.

This really works! I had to rock the driver's side second row seat a bit after pulling the underneath the seat strap. (See owner's manual re: strap.)
