Baby KNOX is modern, sleek, and stylish, with several unique and innovative security features. KNOX contains a multidirectional strap that can be worn backward or forwards.

The use of the multidirectional belt is optional if you are looking backward, but UPPA strongly recommends using it whenever possible as it will reduce rotation in the event of a head-on collision with the car and will attach to the tether belt of the vehicle seat.

Each of our 3 models goes very well with the KNOX. Once the trim is removed by 25 lbs, a smaller child can have a significant gap between your body and the unique crotch strap/buckle location.

It is important to note that in hindsight, UPPAbaby does not require the usual “on or under” belt-positioning. His manual states that with active support, the headrest should be positioned so that it leaves some space between the lower wings of the head and the child’s shoulders.

Buying Guide Best Convertible Car Seat

Before buying any convertible car seat you should read the buying guide.


Each convertible car seat has the size and weight restrictions on rear-facing, forward-facing, and, if applicable, booster seats. Always make sure that your car seat is configured according to your child’s current size


If your vehicle is not LATCH compliant, you will likely install your car seat using your vehicle’s seat belt. Consult a professional if you need help adjusting according to your car seat manual.

Seat adjustments

Because a convertible car seat can watch your child from newborn to toddler, look for one that can grow with multiple headrest positions and tilt options. With an unthreaded belt, you can easily adjust the seat settings without having to reconfigure your seat belt.


Over time, the materials in a car seat can compress or wear out, which is why all convertible car seats have a stamped expiration date. If you plan to use the same seat for many years or for several children, consider the recommended use.


If you have decided on a convertible child seat, you should test immediately upon receipt how well it fits on the back seat of your vehicle. That way you can change it and install a new one if it doesn’t work before your baby comes.
