Harmony Olympian – 9 years, 60 lbs., 49 inches


For short-term use, a 6+ age rating would be appropriate. This seat does come with a seat belt adjuster as well to help obtain proper fit. All three of my kids fit pretty well in this seat. The 10-year-old did say it was a bit tight to buckle and complained it was hard when asked how it felt. The other two children had no complaints. This seat requires head support at all times and has a 6 year expiration.

This is a big booster, not one that will easily work for three across. Not only because it’s wide, but also because of its narrow belt path under the armrests. With such little space, it can be very hard for kiddo to get buckled. It was great that is was so wide and deep, it fit a large 10-year-old well. The booster itself is so high though that it felt he was almost too boosted. This actually fit the 7 and 9 year olds because they were shorter and a little extra boost wasn’t a big deal. This would be a good seat though for a kid with long legs who needed more support. Check out some other suggestions for boosters for your bigger kid HERE.

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 neck; the lap belt should be lying low on the hips, touching the tops of the thighs. Read more HERE about correct seat belt positioning with a booster. This booster was awarded a Best Bet rating from the IIHS for 2013 for models built after May 2010.
