We already have a two Clek Fllo carseats for our 4 year old, and we just purchased 2 more for our one year old, who is outgrowing his infant seat. The color name on this seat is appropriate, because that's what we call it -- the Tank. I feel so confident and comfortable having my children in these seats. They are solid and comfortable. We have two cars, and one of them is an older and smaller model than most -- a 2007 Honda Fit. It feels so small now, with our family of four, that I really wanted a strong child seat in there. The Fllo gives me the confidence I need that my kids are seated as safely as possible. Note on fit in the Fit: We've squeezed the Fllo in WITH the anti-rebound bar, behind the passenger seat side of the car. It does leave for very little legroom for the front passenger seat (we make it work, but we're fairly short and my husband generally drives the car with the passenger seat empty). However, the anti-rebound bar is optional, so if you left that off I think there would be plenty of passenger seat legroom (well, as much legroom as you'll get in a Fit ;)). Our other car is a Subaru Outback, and these fit great.
ProsSolid like a tank
comfortably upright, so kids have great view
Anti-Rebound bar is a great feature not found in a lot of US carseats
less toxic flame retardants than many other brands
Can do super extended rear-facing -- make sure you don't exceed rear facing Latch weight (we did at age 3) -- seat belt is actually a better install with this seat, esp for older kids.
ConsExtra large size and heavy weight make this seat a hassle for travel. does not fit thru TSA X-ray scanner, so needs to be swabbed at airport.
Best Usesage 9 months
