Product Overview

The UPPAbaby Alta Car Seat

The UPPAbaby Alta booster seat balances comfort, ease of use, and key safety features for older kids. With its spacious design and thick padding, it keeps kids cozy while proper belt positioning helps keep them secure.

The Alta is a high-back booster meant for older children, approximately ages 5-10 years old. Its design accommodates growing kids, with a weight range of 40-100 lbs and height range of 38-57 inches.

Key Features

What features set this car seat apart from others?

  • Rigid LATCH connectors for easy, accurate installation and added stability when not in use
  • Seven-position headrest that adjusts as kids grow
  • SecureFit belt routing system with guides and a lap belt positioner for proper seatbelt positioning. The SecureFit system combines well marked belt guides with a recessed shoulder belt well.
  • Side impact protection pods on the seat shell absorb crash forces
  • Machine washable seat pad and removable cup holder simplify cleanup

What Real Owners Think

Here's what actual owners of the UPPAbaby Alta had to say based on hundreds to thousands of reviews we've analyzed from Amazon.

Pros Cons
  • Many parents found the booster seat easy to install, specifically using UPPAbaby's rigid LATCH system.
  • It was also widely reported that the kids themselves found the booster seat comfortable
  • The aesthetics (beautiful colors), spaciousness, and easy maintenance (cleaning) were frequently called out as positives.
  • Issues with the shoulder belt slipping out of position repeatedly came up. There is a possible design flaw with the shoulder strap slot that allows the belt to frequently slip out.
  • For some, the cup holder sticks out from the booster seat so far that they are unable to close their car door.

Who Should Buy the UPPAbaby Alta?

Families with kids between 5-10 years old who have outgrown their forward-facing harnessed seats will appreciate the Alta's belt positioning features. Its spacious, padded seat and adjustable headrest accommodate growing children in this age range. For parents who drive bigger vehicles like SUVs or minivans with ample rear seat space, the Alta's wide base provides comfort without cramping smaller backseats. Since it is on the heavier side, the Alta may not be the best choice for families who need a lightweight, portable booster. The Alta's size and secure installation make it a sensible choice for families with one larger car looking for an adjustable, long-lasting booster for their older child.

Final Verdict

The UPPAbaby Alta earns high marks for its emphasis on proper belt positioning and ease of use. While a few users faced challenges with shoulder belts staying put, most found the seat secured their child well. Between its padding, spacious design, and adjustability, the Alta keeps kids comfortable. For families seeking a safe, high-quality booster as their child grows, the Alta combines thoughtful amenities with conscientious safety features. Periodically double checking belt placement is recommended, but overall the Alta delivers when it comes to protection and comfort.
