Excerpt: It's simple to secure your child in Graco's Nautilus 3-in-1 car seat. We found it easy to tighten and loosen the harness, and install with a seatbelt or LATCH system (though adjusting the angle proved more tricky). The Nautilus can also convert from forward-facing with a harness to forward-facing with a belt positioning booster to forward-facing with bottom booster as your child grows. And — bonus — the car seat cover is machine washable.
Pros: Easy to install with a seatbelt, Easy to install with LATCH, Easy to tighten and loosen harness, Easy to secure child (We used our 8-lb. GHRI test dummy), Car seat cover is machine washable
Cons: Some minor assembly is required, Harness height has to be rethreaded, which is difficult to do, Car seat cover is tough to remove
