How much room does she have left in the harness?
IIRC you said in your booster post that she has about an inch in the Regent. I am curious because I am trying to help decide between a Regent and a Nautilus for my 4.5yo niece with Autism. She is at the top slots on the Cargo. She still fits the Futura, but it is expiring in 5 months and she needs more padding(sensory issues). I am hoping that the Galaxy cover is plush so that she will like it. She loves her cousins Apex, but they don't have head support in their Suburban, so that one is out.
I'm not entirely sure how much room she has left, measurement-wise. I didn't measure. By the time I sat her in the Nautilus to take the pics we had already been wrestling with the KDMF install seats for 2.5 hours, and she was hungry and annoyed that I was forcing her into the harness.
Just by looking at the pics, I'd say she's got at least half an inch, possibly a full inch left. When I sat her in a Regent over the weekend the straps were in the second-to-top slots and I didn't have time to move them up, where she would need them, so I just stuck my finger in the top slots and based on that, I think she had an inch left, maybe an inch and a half. In my experience the Regent's height room can differ greatly depending on the install method and vehicle it's being installed in. In our Husky I thought she had more like two inches left; I'm wondering if the Regent has slightly shorter top slots than the Husky
or if it just fit differently because of the seat it was sitting on, or if dd's torso has really grown an inch since the last time I sat her in the Husky.
Either way, dd has been too tall for the Futura for quite awhile, so if your niece still fits the Futura I'd say she's got quite awhile in the Nautilus. Most folks are reporting that the Nautilus has top slots ALMOST as high as the Regent. H has put on some weight recently (thanks, school lunches
) and is 59 pounds, so it's a toss-up on whether she'd outgrow the Nautilus harness by height or by weight. I think that's awesome, because sooo many seats are outgrown by height long before the harnessed weight limit.
