How do I remove the rear seat in a 2011 Toyota Avalon?

To remove the rear seats in Your Toyota Avalon, slide the front seats forward and secure any seatbelts to prevent sensor damage. Pull the rear seat cushions up and remove. Next push the rear seatbacks forward to reveal 3 bolts attached to the floor. Unbolt these and push the seats backward to reveal the same configuration at the front of the assembly. Unbolt them from the floorboard of the car. The assembly can be removed after unbolting at least 6 bolts and lifting the part out of the metal tracks still screwed to the floor. Make sure to put the bolts back in their holes to prevent loss.
