What is a Convertible Car Seat?

A convertible car seat is designed for use from birth until a fairly high weight, typically 40 to 80 pounds. It will both rear face and forward face, and some convert to high back boosters after your child outgrows the weight limit. Convertible car seats are not meant to be taken out and carried around like you would with an infant seat.

How did you pick the best car seats for three across?

When looking for car seats that would work in our small car, we used the following criteria. We made sure the car seat was safety tested with high ratings for both infants and toddlers. We looked only for seats that would fit three across even in small cars. We made sure the seats were a good value and would last for many years.

How do I measure for a narrow car seat?

If you need to fit triplets together in one small car, you must look for a narrow seat. Before making your purchase, measure the backseat of your car to see how much room you have to work with. Then, measure your children as well. You need to make sure they fit within the parameters that the car seat can accommodate!
