UPPAbaby ALTA Booster Car Seat



UPPAbaby's first high-back booster car seat for older children, the UPPAbaby ALTA includes numerous features that keep your child comfortable and help parents safely install the car seat.

The UPPAbaby ALTA is fully lined with EPP foam, the toughest type of protective foam used in motorcycle helmets. In a unique feature, a lap belt positioner tab in the bottom of the seat keeps the vehicle seatbelt in place, preventing the belt from riding up into an unsafe position.

Rigid (metal) LATCH connectors provide the most secure connection to your car and make the seat easier to install, too. Side impact pods on the side of the seat absorb energy in a crash, helping to divert forces away from your child.

A spacious design and adjustable headrest with seven positions ensure your child stays comfortable in the ALTA as she grows from 40 to 100 pounds (approximately age 5 to 10).


  • SECUREfit belt routing system ensures proper fit for both lap and shoulder belt
  • Rigid LATCH connectors secure the car seat and ensure easy installation
  • Seven-position adjustable headrest and spacious design accommodate growing children
  • Active Response Headrest utilizes absorption and recovery properties of foam including EPP to deliver protection to the head and neck

  • Included dishwasher-safe cup holder can be attached to either side of the seat

Looks great

I love the design of it. Especially that it seats low. It also connects easily. The only reason I am giving it a 4 star is that for most kids who are going to use this, you need to move up the backrest a lot and that leaves very thin padding on the back. For a simple car seat from a top brand that costs $180, I expected thicker padding.

The Latch connectors may not work for the center seat

I’m so bummer because the seat itself is very nice looking and the structure you can tell is just safe. Unfortunately the hooks in the back are straight and so they don’t fit in the middle of my car... only hooks into the side seats... this is a big bummer because I don’t feel it’s super safe. And the seat belt is def tricky for kids if the buckle is in the seat. My son was able to get in and out of his seat easy with his actual car seat. I thought this one would be easier but unfortunate it does take a lot of effort to strap in. My sons name is Lucca so I was super excited about the seat, maybe its not a good fit for every car.
