So I believe these car seats changed names but they're the same thing. We're expecting baby 3 and don't really want to upgrade our SUV. We have a santa fe which is mid size and should fit these car seats 3 across. Does anyone have these car seats? Are you happy with them? Do you have 3 across and how well does it fit?
We will likely keep DS1 in a 5 point harness type seat for another 2-3 years as he is small for his age and I just feel more comfortable with him in it. The biggest down side I can see right now is not being able to have an infant car seat to get the baby in and out easily but I barely even used one with DS2 so I'm really not that worried. I plan to baby wear anyways.

Re: Diono Radian?(Sunshine Radian)
We have these car seats and three of them fit in our Nissan Sentra. Two Radians fit with our infant car seat (Baby Trend) as well. I imagine you could easily fit two Radians and an infant seat in a Santa Fe.
The seats are fine, the kids fit fine in them and I like that the back is high for FF purposes. They're a pain to RF in a small car, though. There's a separate wedge you can buy to RF but we just use them as FF seats. My biggest complaint is that they weigh a lot and are annoying to transfer from one car to another. We don't move them often though so it's not that bad for us.
