Q: Does the 2 year head fall over when asleep?
A: Thank you for your interest in our products! The Nautilus 2.0 LX 3-in-1 Harness Booster Car Seat is not designed for sleeping. However, we understand that children often fall asleep while riding. It’s normal for a child’s head to fall forward or to the side during sleep, as their neck muscles are still developing. This can also be influenced by the car seat’s recline angle, harness positioning, and the contour of your vehicle’s seat. We hope this helps! - The Graco Team

Q: Can this seat be installed in a car with a seatbelt only.
A: Thanks for your interest in our Nautilus 2.0 LX 3-in-1 Harness Booster Car Seat! You can install the 5-point harness mode with the vehicle's seat belt rather then the included latches. When in the high-back and no-back booster modes the vehicle's seat belt should be used to secure your child into the seat. In the booster modes you can use the latch system up to 100lb but it is not required we do recommend to make sure that the seat is secured no matter what when the seat is not in use. Hopefully this helps! - The Graco Team
