How easy is it to replace Nautilus harness?


New member
Background: 6yo outgrowing Nautilus harness and when I tried her in it for booster fit (pulling harness to the side, putting seat belt on through guides, and without going anywhere) some months ago, it did not look like a good fit.

However, when I tried her now (in a different car, so that may have made the difference), it looks like it does fit her as a booster (belt low over legs, shoulder belt over mid shoulder), so I'm considering removing the harness and seeing how she does. but, I'm feeling a little intimidated by removing the harness. If she does not do well or we decide we need this seat for DD2, will it be easy to put the harness back in?

Also, I thought I could use latch and tether with this seat during booster use and that is important to me. but I just read a recent thread disputing that. I don't know what to think. If I cannot, I might prefer a dedicated booster. Are there any other advantages to using a dedicated booster versus nauti in booster mode? Thanks!

Also, as long as I'm asking questions, how often do vehicle head rests go up high enough to use the boosters that require head rest behind them (e.g. monterey, vivo) to capacity? I was noticing that our car's head rests don't go much higher than the nautilus head piece and that doesn't seem that tall.

The GN harness removal/replacement is easy-peasy.

Take off the cover and lay the back down. There are two arms that go through loops in the harness. Release those to slide the harness off or on. The worst parts to replacing are getting the crotch buckle back in, and routing the top over those stupid rollers and boxes.

eta: you only have to remove the cover on the bottom- just enough to lower the back and access the arms.
