What Is a Convertible Car Seat?

A convertible car seat is a seat that is made to grow with your child from the infant stage until they are old enough to sit in a regular seat belt. For children from 4 to 40 lbs, the convertible seat needs to be installed rear-facing and slightly reclined. For the older child, 20-65 lbs, the convertible seat needs to be installed front-facing, allowing them to sit upright in the seat.

Are Convertible Car Seats Safe?

Convertible Car Seats are safe and offer many advanced safety features. They are crash tested and must meet or exceed all federal and ASTM safety standards before they can be put on the market. As long as parents are attentive to their child's weight and height changes and adjust the seat accordingly, they are safe to use until the child no longer needs the seat.

Are Convertible Car Seats Comfortable?

Because convertible car seats are built to last for many years, they are designed with a child's comfort in mind. With features such as different reclining positions, adjustable headrests, harnesses, and buckles, the child's comfort will be easy to achieve.

Why Choose a Convertible Car Seat?

A convertible car seat is the right choice for many people because they offer the convenience of only buying one car seat instead of multiples as their child grows. Once correctly installed, these car seats do not have to move until the child is ready to advance to the next stage.

Is a Convertible Car Seat a Better Choice than a Standard Child Seat?

Children can quickly outgrow standard child seats and then they have to be replaced. Convertible car seats take away the need for replacements. By making simple adjustments to accommodate a child's height and weight, the convertible car seat will last as long as the child needs it.

How to Install a Convertible Car Seat?

Most convertible car seats offer two ways for installment into a vehicle. They all come with a seatbelt path underneath them so the car's seatbelt can be threaded through and then secured in place. Many brands come with latches that attach to the anchors in newer vehicles. Once buckled, either with anchor latches, or with the seatbelt locked, the car seat should not move more than an inch from side to side. If rear-facing, the seat should be reclined slightly to keep an infants airway open. If front facing, the seat will sit straight up. Please refer to the instruction manual that comes with the seat for specific instructions.

How Do I Use the Convertible Car Seat Once It Is Installed?

Once installed correctly, the seat is ready to use. Simply adjust the harnesses and buckles to fit your child snugly. Please refer to your state regulations and your instruction manual provided for specifications.
