  • Base Weight: 9 lbs. 
  • Orientation: Rear-facing 

The MESA V2 Infant Car Seat is the upgraded version of UPPAbaby’s MESA Infant Car Seat (you can read our comparison article here).

The V2 is UPPAbaby’s most popular car seat, evidenced by its many 5-star reviews.

For use from birth to age 2 (approximately), the MESA V2 is packed with comfort and safety features that keep your child snug and safe while in the car. Things like a large padded headrest, an infant insert for perfect positioning, and an anti-rebound bar keep baby and parent at ease during trips.

The V2 is easy to install in any backseat using either UPPAbaby’s SMARTSecure System or LATCH, and it also has European belt routing to keep it secure when used without its base.

Additionally, you can directly attach the V2 to UPPAbaby’s VISTA and CRUZ strollers or use adapters to attach the seat to the MINU and RIDGE strollers.

UPPAbaby also offers a range of accessories to complement the V2:

MESA Rainshield (wet weather) 
MESA Cozy Ganoosh Cover (cold weather) 
MESA Cabana Weathershield (all weather) 
MESA Safe Travel Bag 
MESA Infant Car Seat Base

  • Suitable for children from 14 to 65 lbs., or up to 49" tall (approximately 1 to 6 years) 
  • Infant Insert: 14 to 25 lbs. 
  • Rear-Facing: 14 to 40 lbs.
  • Forward-Facing: 25 to 65 lbs. 

Available in 4 striking colours, the KNOX is a convertible car seat — meaning it can be positioned rear-facing for an infant or forward-facing for older children.

Of note, it’s a stage 2 car seat (you could also use it as a secondary car seat). While the KNOX isn't designed for tiny newborns, the seat comes with an infant insert for babies that meet the minimum 14 lbs. threshold.

UPPAbaby packs the KNOX with safety features such as:

  • A Koroyd base that absorbs energy and crash forces
  • A tether strap that keeps the seat from rotating in the event of a crash 
  • Protective, dense EPP foam 
  • Side impact protection pods 

The KNOX installs via SMARTSecure or LATCH, includes a no-rethread harness, has machine-washable seat covers, and is reclinable for ultimate comfort.

Should you need to take the KNOX with you on a trip, you can pick up the KNOX Travel Safe Bag for easy transport.

  • Suitable for children from 40 to 100 lbs., and 38” to 57” in height (approximately 6 to 10 years old) 
  • Dimensions: 20” L x 19” W x 25.5–33” H (height headrest in lowest and highest positions) 

The ALTA 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. UPPAbaby throws in a cup holder (which can be attached to either armrest), and the seat’s fabric is removable for easy washing in the event your child spills anything on it (which will 100% happen at some point).

Accessories for the ALTA include:

UPPAbaby ALTA High-Back Booster Seat in Blue With Little Girl Sitting Inside, UPPAbaby ALTA High-Back Booster Seat in Black With Little Girl Smiling and Sitting Inside, UPPAbaby ALTA High-Back Booster Seat in Blue Side View


UPPAbaby designed each of these car seats with quality and care to ensure your child not only enjoys their time in the car but that they’re comfortable and safe during every trip.

You can use the MESA V2 for their first car ride coming home from the hospital, the KNOX as they enter toddlerhood and start school, and the ALTA to give them a boost until they reach double digits and are big enough to use a conventional seatbelt.

With these seats catering to each stage of your baby’s growth, UPPAbaby is there to help out every step of the way!
