    UPPAbaby ® Aria ™ Declan Oat Melange Infant Car Seat and Base
    Clearance $349.99 reg. $499.99

    This infant car seat may be ultra-light—only 6 pounds!—but it's a heavyweight when it comes to smart features. A red-to-green visual indicator, adjustable foot for leveling, and auto-retracting LATCH system ensure no-fuss installation. Cushy, machine-washable fabrics—along with a back panel for ventilation and sun canopy for protection—maximize comfort for infants. And it's engineered to be ultra-sturdy in case of collision, with an anti-rebound side panel and optional anti-rebound handle position. The UPPAbaby ® Aria car seat is compatible with various UPPAbaby strollers, making for easy car-to-stroll transitions.
