The question makes no sense.
Booster seat in the middles seat of the back of the car.... of course, that would be the safest spot if you have side impact airbags....
Now I am taking a guess with the last part of the question... with a back PACK? I would advise no as that can be a safety issue.
If your talking about the booster seat without a back then NO, It is not safe for the child to ride with only a lap belt.
The recommended age for transitioning a child from a booster seat with a back to a booster seat without a back is typically around 8 to 12 years old, or when the child reaches a height of 4 feet 9 inches.
A child can transition to a high back booster seat when they outgrow their forward-facing car seat, typically around the age of 4 and at least 40 pounds.
That depends on how old of a child. If the child is in a car seat or booster seat, then no. Studies and actual accidents have shown that children and infants can be beheaded in the front seat if airbags deploy. The child needs to be buckled in the back seat, center if possible.
When transitioning a child from a car seat to a booster seat at age 5, it is recommended to follow these safety guidelines: ensure the child meets the height and weight requirements for a booster seat, use a high-back booster seat for added protection, properly secure the seat belt across the child's shoulder and lap, and make sure the booster seat is installed securely in the vehicle.
The maximum weight limit for a child to use a high back booster seat is typically around 80-100 pounds.
You're probably thinking of a booster seat.
Do this to check if a child can leave a booster. The child should place their back on the seat with their big ass in the end. If the child's feet can touch the ground they are ready. Most children stop using booster seats when they are 7.
The recommended age for transitioning a child to a high back booster seat is typically around 4 to 8 years old, or when they outgrow their forward-facing car seat.
A child can start using a high back booster seat when they have outgrown their forward-facing car seat and are at least 4 years old and weigh at least 40 pounds.
To ensure proper installation of a high back booster seat for your child's safety in the car, follow these steps: Read the manufacturer's instructions carefully. Place the booster seat in the back seat of the car. Secure the booster seat using the seat belt or LATCH system. Adjust the headrest and shoulder belt guide to fit your child's height. Make sure the seat is securely installed and does not move more than an inch in any direction. Have your child sit in the booster seat and buckle them in properly. Regularly check the installation to ensure it remains secure.
no, but you have to connect the seatbelt connected to the actual car to the booster seat. but there is a seat belt in the middle for a car seat.
