Harmony Youth Booster Review

(Last Updated On: October 27, 2017)

Ready for a backless booster for your not so little Little or maybe you need to have spare boosters on hand for friends or when your child travels with others? The price of the Harmony Youth booster and compact size make it a great option for many reasons. Let’s check it out!

CSFTL Quick Stats

  • Weight range: 30-100 lbs. (Canadian versions are 40-100 lbs.)
  • Height range: 34-57″
  • Expiration: 6 years
  • IIHS Best Bet



For shorter trips, a 6+ age rating would be appropriate if the child can remain upright even while sleeping. We generally recommend using a high back booster until the back has been outgrown as it does often position the seat belt better on small children and the back helps draw limits for children who aren’t used to the freedom a backless booster brings. The Youth does come with a seat belt adjuster to help the shoulder belt fit. This can be helpful when petite kids need to use this seat or odd belt geometry requires the guide to perfect belt fit.  Like all backless boosters, the Youth requires head support up to the top of the child’s ears.

This seat is very narrow and can work well in 3 across situations. Because it is so narrow, it can be hard for bigger kids to get the belts under the short armrests as required. You can see here how the belt is peeking out from under the armrest. It does not have LATCH so can be a bit wobbly when kids are getting themselves buckled in because of its narrow design.


Fit to Child

Harmony Youth- Olivia, 6.5 years, 55 pounds, 48 inches


Olivia is 6.5 years old, 55 lbs., and 48″ tall. She doesn’t use a backless booster full-time, but does well in one as a spare when traveling with other people. The Youth provides a proper belt fit on her and is light enough for her to carry to school or a friend’s house if needed. It’s also very narrow so helpful when riding with other children next to her. She fit well without the belt adjuster but using it makes it better still.



Ilana is almost 9, 54″ tall, and wears a 12/14. She fits great in the Youth even though it’s a more narrow booster. It does make it a little harder to get the lap belt under the armrests though. Ilana is still just a few inches short of being able to safely pass the five step test and her bones are too immature to withstand crash forces alone. Even though it does come with a belt adjuster, she’s plenty tall enough to not need one to keep the belt properly positioned across her collar bone.



Important Information: Where to Find

domharmonyExpiration  The Youth has a 6 year expiration. The date of manufacture sticker is easily seen on the back of the seat. This seat was manufactured in 2010, so will expire in 2016 on that date.


Manual Storage  The manual can be stored under the cover for easy access and safe keeping.


FAA approval  The Youth requires a lap/shoulder belt so is not FAA approved. However, it’s small and light enough that carrying it on an airplane to use at your destination would be very easy.



  • Inexpensive
  • Lightweight
  • Narrow


  • Short, narrow armrests can be difficult to thread belt under
  • Not much padding
  • No lower anchors


Overall Thoughts

The most important part of using a booster seat is that the child is mature enough to sit properly for the entire ride, and that the belt fits properly. A good booster fit positions the shoulder belt even across the torso – not sliding off the shoulder or cutting into the face; the lap belt should be lying low on the hips, touching the tops of the thighs. This booster was awarded a Best Bet rating from the IIHS for 2013.

The Youth seat gives a proper belt fit, especially when using the shoulder belt adjuster. It’s price and size make it a top choice for three across and having extra boosters on hand.



You can get the Harmony Youth Booster at Wal-Mart for around $14.
