This car seat has been better than I even hoped it would be. I had read reviews about children that hated their infant car seats but love this one. I thought they were exaggerating, but my daughter does it too. She squeals with delight whenever I got to buckle her in, she even tries to help fasten it.
Okay, now to what really matters: SAFETY! This car seat is solidly constructed and has amazing stats. Sunshine Kids has a youtube channel that shows their NCAP testing, which is much higher than the industry standard that most car seats use. (As a side note: they also have helpful videos about installation and properly fitting it on your child.) It is also rear-facing up to 45 pound which should easily meet the current AAP recommendation that all children under 2 should rear-face.
We have a Buick Rendezvous and we could easily fit 3 in the backseat. I've heard people say that it didn't fit in their smaller cars, but as long as you can get the proper 45 degree angle the NTSB says a car seat can touch the front seats and be effective (as of 2011). When we have baby #2, I'll probably buy this seat outright and skip the infant seat. Time will tell.
Sunshine Kids strives to use ecologically-friendly materials and production methods and is chemical-free.
All this being said, the best car seat for your child is a car seat that fits in your car and your child and that you'll both enjoy using.
