UPPAbaby Aria Lightweight Infant Car Seat

A safe, featherweight design with a foolproof, intuitive installation.

Weighing just under 6 lbs, the Aria offers lightweight portability without compromising your child’s comfort and safety. Designed for busy families on the go, the Aria combines advanced safety features with a fuss-free install—base or no base—for everyday flexibility and peace of mind.

The Aria’s innovative SMARTSecure system eliminates the guesswork and guarantees a snug, straightforward installation every time. An indicator window changes from red to green for a quick visual confirmation your base is correctly installed. Unique self-retracting LATCH connectors tighten with zero effort, minimizing installation errors, and a built-in lock-off ensures securing your car seat takes only seconds. The base has an adjustable load leg and anti-rebound panel that absorb impact and minimize crash forces.

European routing allows for easy installation without the base, making the Aria ideal for travel or city living. An adjustable, reinforced headrest with EPP foam provides added side impact protection, and a fourth rebound handle position reduces motion during rear-impact collisions. No-rethread harness straps ensure a perfect fit as your baby grows, and buckle storage pockets simplify securing your little one without hassle.

The ergonomic carry handle has a comfy grip for easy toting, and a large UPF 25 hideaway canopy keeps your baby shielded from bright sunlight. The Aria is made with DualTech FR-free fabrics and is GREENGUARD Gold Certified, ensuring your baby’s environment is as safe as it is cozy.

The Aria clicks right into VISTA and CRUZ strollers without adapters, making your switch from car to stroll smooth and easy. And if you’re using MINU or RIDGE, quick-to-attach adapters convert your stroller into an adventure-ready travel system.
