    FAQS :

    What is the rebound bar, and how will it affect children who are forward-facing or booster-ready in the future?

    In order to control rebound or reactive motion in the opposite direction of impact during a collision, the anti-rebound bar is a steel bar that fastens to the foot end of the automobile seat. The anti-rebound bar is only utilized while rear-facing.

    Is there a weight restriction on the latch system?

    The weight restriction for the SuperLATCH is actually for the anchor points in the car; it applies to the combined weight of the kid's seat and the youngster. The maximum weight is 65 pounds.

    Does the cup holder fit into the slot securely?

    Yes, there are holes adjacent to the seat bottom on either side of the seat where you may enter the cup holder's metal stem to attach it. You will need to use your fingers to search for the hole because it is relatively concealed.

    What height is required for your child to use the adjustable headrest?

    The third harness slot for your child must be used, and the child's jaw line must line up with the bottom of the headrest assembly. If any of these two conditions is not satisfied, the headrest assembly must be left in the highest position.

    Has the cloth already been stain-treated?

    Answer: PFCs, which are known to cause cancer in people and have been found in tests to alter normal endocrine functioning and lower immunological function, are used in the manufacture of anything treated to be stain-resistant, including sprays like Scotch Guard.

    Has this ever been fitted into a Toyota Prius C or Aqua?

    Even so, our seats are made to accommodate the majority of vehicles. Most cars may accommodate the Radian R-series All-in-One car seats when they are arranged three across. Radian car seats are all 17" broad and require a total of around 54" to install three across in a row. Description: Radian 3QX vs 3RXT
