The Foonf packs the most crash engineering into the narrowest shell here. Clek's REACT Safety System pairs Rigid-LATCH with energy-absorbing crumple technology, which Clek says reduces the forces transmitted to a child in a frontal collision and gives forward-facing performance comparable to a rear-facing installation. Rear-facing, it holds children from 14 to 50 lb and 25 to 43 in, and Clek says most kids can stay rear-facing until their fourth birthday. Forward-facing covers 26.5 to 65 lb and 30 to 49 in. An anti-rebound bar and rear-facing base come in the box. The 16.9 in seat width makes three across possible in many cars. The costs are real: the seat weighs 38 lb rear-facing, newborns need the infant-thingy insert sold separately, and it sells for $649.99 on sale. Clek includes a Lifetime Extended Warranty on new seats and a 9-year expiration.
