UPPAbaby Alta High-Back Belt-Positioning Booster Seat Review

So, you’ve got a dilemma…Your little baby isn’t quite so little anymore! They’ve outgrown their convertible car seat, but they’re not quite big enough to safely sit in the back seat of your car yet.

Enter the Alta High-Back Belt-Positioning Booster Seat from UPPAbaby!

Designed with safety and style in mind, this booster is the perfect final seat for your child after transitioning from the Mesa V2 Infant Car Seat and the Knox Convertible Car Seat. Equipped with a high back and headrest, the UPPAbaby Alta provides your big kid with a safe and comfortable seat while they continue to grow into childhood.

A Safe Seat

Safety is always a top priority when it comes to your child's car seat, and the Alta's safety features make it stand out from the crowd. First, it boasts Side Impact Pods. These bad boys are positioned on the side of the shell and are designed to absorb and disperse crash forces. It may seem like a small feature, but it can make a huge difference in the event of an accident. You can rest easy knowing your little one is protected from every angle.

The Alta also features special foams that provide added side impact protection. These are strategically placed to provide extra cushioning and absorb energy in the event of a crash.

Finally, we can’t forget about the seven-position Active Support Headrest — a game-changer for parents with growing kids. The headrest can be adjusted to accommodate children of different heights, with a range of 25.5 to 33 inches, so your child will always be comfortable and supported, no matter how fast they grow!

Dreamy Booster Bliss

Let's talk about the comfort features that make kids love this booster seat.

The Alta’s spacious design is perfect for 6 to 10-year-olds. With a weight range of 40 to 100 pounds and a height range of 38 to 57 inches, there's plenty of room for your growing child to stretch out! The seat also has a width of 19 inches, so even the squirmiest of kids will have room to get comfy.

The Alta features dual armrests that provide extra comfort and support for your child's little arms. No more sore elbows from resting on hard surfaces — your little one can now relax in style.

Of course, no road trip is complete without snacks and drinks. The Alta includes a removable cup holder that can attach to either side of the seat so your little one can easily reach their favourite beverage, keeping them hydrated and happy during long car rides. You can also purchase a replacement (or second) cup holder if need be, and a travel safe bag is available for you to bring the seat on long journeys and keep it in tip-top shape!

No-Fuss Setup

Connecting the Alta to your vehicle is a breeze — you don't have to be a rocket scientist to do it (trust us)! The rigid LATCH connectors are like superheroes that swoop in to save the day. They secure the booster to the vehicle seat, guaranteeing proper alignment and positioning for everyday use. You can relax, knowing your little one is safe and secure in the back.

That's not all! The SecureFit belt routing system is here to make your life even easier. With its lap belt positioner, it ensures the proper fit for the lap and shoulder belt, while preventing slippage. This means you won't have to deal with any fidgety, squirming toddlers on the go!

Eye-Catching Upholstery

The ALTA is a stylish booster that comes in five different colours.

The first option is Noa, which features a heather blue back and a navy blue seat. This unique colour combination lends a touch of class and elegance, complementing a variety of car interiors.

Jake is your second option, with a dark grey back and black seat. This sleek look is perfect for parents who want a classic, timeless design. UPPAbaby’s Lucca features a teal seat back and a dark green seat, which adds a pop of colour to any car’s interior.

Morgan has a grey back and a black seat, for a neutral-yet-versatile combination, while Sasha uses a light grey back, a dark grey seat, and pink trim.

In addition to its stylish colours, the ALTA also features removable and washable seat fabrics, a super handy feature because spills and accidents are 100 % destined in your future!

Adventure-Ready Ride

The Alta High-Back Belt-Positioning Booster Seat is not only a safe and secure choice for parents but also a stylish one that offers big value in a small package. UPPAbaby serves up plenty of colour options, easy maintenance and setup, ideal safety specs, and cozy comfort features to make this one of the best booster seats for your little one. So, if you're a busy parent with a million things to do (who are we kidding, of course, you are!), rest assured that the ALTA makes life on the road stress-free, so both you and your child can simply sit back and enjoy the ride.
