For extra-snug security when they haven't quite grown into their car seat yet, this infant body support from JJ Cole makes all the difference. It fits snugly around infants of all sizes, and the head support is both adjustable and detachable, giving it the flexibility to accommodate your baby's growth. It's even reversible, with plush chamois on one side and a soft fabric blend on the other, for superior comfort no matter what the season.
