A lockoff is a built-in feature that locks your seat belt for you. When a lockoff is present, you will not need to engage the locking mechanism of the seat belt.

A belt tensioner tightens the seat belt for you with little effort; it uses leverage to make the job easier. It presses the belt into a channel(s) to shorten it mechanically and create the tension.

Comments
Graco calls this a “3-in-1” carseat, but it’s not a traditional 3-in-1 carseat in that it doesn’t rear-face/forward-face/booster. It is forward-facing only for older kids with a harness mode and 2 booster modes.
