A fabulous seven-year warranty and the fact that this can serve as “the only car seat you’ll ever need!” make Cosco’s Alpha Omega 3-Stage Car Seat hard to beat. Three seats in one (an infant, toddler, and auto booster seat), the Alpha Omega can be used for children from 5 to 80 pounds. Infants from 5 to 35 pounds should be seated in the rear-facing position (though the seat doesn’t recline as much as one might like and takes up a lot of car space, and some parents say small babies get swallowed up by all that seat); toddlers from 22 to 40 pounds should be seated in the forward-facing position; and kids from 30 to 80 pounds should be seated in a booster (no tools are required for conversion to booster). A tether option is included with the award-winning car seat, and installation and usage are a breeze thanks to an instructional video. Features include a parent-friendly five-point harness; a three-position recline for infants and toddlers; generous padding for extra comfort; soft, removable and washable pads; an adjustable headrest; and much more. Added applause from parents goes to the clever harness height adjustment feature, which, unlike most car seats, never requires tedious re-threading. The headrest and harness adjust easily as the child grows, and the booster is designed so vehicle lap and shoulder belts are positioned properly and safely for children.
