The Baby Backseat Mirror for Car by So Peep is created from baby-safe shatterproof acrylic glass and includes an ultra-strong double strap system to ensure that the mirror stays exactly where you position it. The strap system also ensures that the mirror doesn’t shake or rattle while the car is in transit. This means that you are less likely to be distracted and your child will be not be disturbed by unusually noises or movement. The simple-to-install mirror requires no assembly, and the extra-large convex mirror gives you the best possible view of your child. The mirror also pivots so that it can be adjusted to meet your specific needs. The mirror is not suitable for use with fixed headrests.
