Cosco Summit High Back 3

I bought this model for a Toyota 4-Runner. Unfortunatetly, it is impossible to install in the vehicle in a rear facing position in the middle seat. The car seat itself does not have a rear belt path to use the middle seat lap belt and Toyota does make a middle seat seatbelt extender. The car seat instruction manual is also poorly written. Works fine in forward facing position and is highly rated in crash tests.
