2011 Middle Seat Car Seat Install

Hello! The rear middle seat in my 2011 Prius is a raised up and is quite a bit higher than the two side seats. Does this make it unsafe to put a car seat there? If part of the car seat base is hanging over either side of the bump, it seems like that would make it less safe. Thanks!
