The Baby Car Mirror by COZY GREENS provides a fully adjustable, crystal clear view of your child while he or she is in a rear-facing car seat. The mirror is constructed from strong, sturdy materials, including a shatterproof mirror surface, and has undergone crash testing to meet both US and EU standards. It includes a secure strap system that keeps the mirror in place while driving. The mirror requires no assembly. It just needs to be strapped to the headrest and adjusted to give the best possible view. Requires an adjustable headrest to fit correctly.
