Graco Nautilus SnugLock LX 3-in-1 Harness Booster Car Seat 2018 - North

This item is discontinued.
CLICK! That?s the sound of a secure install. The Graco Nautilus? SnugLock? LX is equipped with SnugLock? Technology for a hassle-free installation using either vehicle seat belt or LATCH. In three easy steps you can feel confident you've got a secure install. The 3-in-1 Harness Booster converts from a 5-point harness booster (22-65 lb), to a high back booster (40-100 lb) and to a backless booster (40-100 lb) to a low profile backless booster (40 ? 120 lb). The Simply Safe? Adjust harness allows you to adjust the harness and headrest together as your child grows , and then the harness stores away easily in belt-positioning booster mode. You?ll appreciate the ease of the fuss-free harness for easy in and out, and machine-washable fabrics. Little passengers will enjoy the dual cup holders, armrest storage and recline. Nautilus? SnugLock? LX grows with your child and is the last car seat you'll ever buy.

Great seat
August 31, 2022
4 years and still going strong. My son loves it and his sister is always wanting to ride in it. My only complaint would be the weight when moving it but otherwise it's great. My kids love all of the "secret hiding spots" for their things

Can't go wrong with Graco

We have several brands of carseats and Graco is by far our favorite. Cup holders on this sit a little lower than other Graco car seats, but we still like the fit and overall style.

My 4 year old says the car seat is comfortable with riding around town, have not gone on long trip yet. He likes the idea of 2 cup holders. My husband has some difficulty getting the bottom buckle to move forward but eventually able to do it.
  • 2 cup holders built in so more stable than the attachment on britax convertible seat

This car seat was incredibly easy to set up and install. It has lots of padding and seems comfortable without being overly bulky. So far we are very happy with this purchase.

Easy install, solid seat!
January 3, 2019
This is the third Nautilus that I have had in my car as a nanny over the last 7 years. I cannot believe how easy this seat is to install now with the SnugLock. Love! The LATCH connections have also improved. It's not the most cushioned seat that I have ever used, but I have never had a kid complain about the comfort. The pockets to stick the buckle connectors in *actually hold them* (this is new!) so they are out of the way while getting a kid out/in. I really appreciate Graco's commitment to safety and testing beyond the required levels. The only thing that is not an easy adjust is moving the buckle strap from one slot to another--but it's doable. I love that everything stores in the seat and the fact that this seat can go from 5 point to HBB to backless.
