Instructions for unfolding/folding the Harmony Folding Booster

At 17.5 inches wide, the Harmony Folding Booster is fairly narrow and tends to work well in three across situations. Here it is with the RECARO Performance BOOSTER and the Combi Coccoro. Unlike other less expensive boosters, this seat offers deep head and torso support. This makes staying upright while sleeping much easier. Top headrest position is around 19 inches. It is able to be adjusted to the top position in the third row of the Town and Country van, but barely. Any taller and it would run into the top and start to tilt. It does have slight retraction issues if the child leans forward, but not as bad as some and not enough to not recommend the seat.

The coolest thing about this booster is it folds! So if grandma wants to keep a booster in her car or you’re flying and want to use it as a carry on, perfect. It’s very easy to fold and has a strap to keep it closed and be able to carry it by. It would be great for carpooling and carrying to school as well.

100% of the Harmony Folding Booster must be on the vehicle seat


The biggest drawback to this seat is it requires 100% of the booster to be on the vehicle seat. This can be a concern in smaller vehicles with shallow backseats.



Harmony Folding Booster – 7 yrs., 62 lbs., 47.5 inches

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. This model just turned 7 and is 62 lbs. and 47.5 inches. This booster seat fits her very well. 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 lay low on the hips, touching the tops of the thighs. Even though this seat fits her well, it was given a Check Fit rating in 2014 by the IIHS.
