I was looking at a second HBB for my bf's little sister for his car and was thinking the Harmony folding booster would be great since he could fold it away when not in use. He is getting the Defender 360 for my DD in his car. Then I realized that the folding booster only has a 6year expiration Seriously this makes no sense to me because the Defender same company that came out at the same time has a 10year expiration. Anybody know the reason for the short expiration? I know 6 is pretty standard but it seems that if they can make a 10year seat they could make them all 10year ya know?
