If you lug your child's car seat between two cars (or from car to trunk), this innovative booster will make life easier! It weighs just 10 lbs., has a built-in handle, and folds in half for easy carrying. Yet it provides cushy, full-size protection to kids up to 100 lbs. And unlike other height-adjustable boosters, the backrest extends completely, so kids are totally supported, even in the highest position. For kids 30-100 lbs. Imported. For ages 3 and up.
