If you are looking for a lightweight infant car seat, the Aria is here to deliver. At just under six pounds, this infant car seat is not only the lightest seat from UPPAbaby, it's one of the lightest car seats on the market.

It also features easy-to-use auto-retracting LATCH connectors and clear visual indicators that turn from red to green when the seat is correctly installed. We also love that the base itself is fortified with an adjustable load leg and an anti-rebound panel, enhancing stability and absorbing energy upon impact.

The Alta V2 High-Back Booster Seat is intended for older children who have outgrown their convertible car seat but still require proper belt positioning while in the backseat.

It comes with rigid LATCH anchors that lock the seat in place, and a 7-position high-back headrest can be adjusted to fit your growing child. The headrest also includes dense side foam for protection in the event of a crash.

Side impact pods are also included to disperse crash forces, and double armrests add an extra dash of comfort.
