The rear seats in the 2012 Toyota Prius V slide, recline, fold flat, and, if you're willing to take a socket set to your car, are easily removed. Taking out one or both seats really increases the cargo space. I cut one of the plastic covers to make it even easier to remove the seats.
Step 1: Remove plastic covers
Remove the four plastic covers at the ends of the seat rails. Three of the four come off easily; the fourth runs almost the entire width of the door, covers some wires, and has a few plastic things and connectors. After removing this larger cover once, I opted to cut it.
Step 2: Unscrew bolts and remove seat
Unscrew the bolts and remove the seat. Look at all that extra cargo space!
Step 3: Cut cover
I anticipate removing the seats more often than I want to remove the large plastic cover. So, I cut a hole in the cover with a Dremel.
