Compact Baby Car Seats: Narrow Enough For Small Cars

Parents want only the best for their kids. That includes not only what makes their kids happy, but what keeps them safe. In that regard, one of the best investments parents can make for their kids is secure and comfortable car seats so their young ones can travel in safety and comfort.

Rear-facing car seats are the safest, so keep your children facing the rear of the car as long as possible.  A rear-facing convertible seat is made for infants and toddlers. As they grow, toddlers and preschoolers should have a forward-facing car seat or forward-facing harness for their protection. Boosters are the next step after a child has met the weight and height limits for 5 point harness. Children should be using one of these forms of seats until they are 4 ft 9 inches in height, which is usually around 8-12 years of age.

Below we give you a run down of the best narrow seats or booster we like in each category.

Tips For Buying Car Seats For Your Child

  • Car seats are different for children of different ages and sizes. Follow the recommendations shared by NHTSA (National Highway Traffic Safety Administration). According to their recommendation, look at both, the instructions– including the size and height– of the car seat manufacturer and the instructions for car seat shared by the vehicle’s manufacturer to make sure they match and fit together.
  • To save time and effort, look for car seats that are easiest to install into the car, such as belt adjustments system, how securely and easily the belt hooks and unhooks, how light it is to carry to and fro from the car, and pay attention to various other harnesses and straps. If your kids are the lunch to-go kind then prefer seats that come with storage areas and easy-to-clean cupholders.
  • For your convenience and savings, choose a car seat that also fits into many different kinds of strollers. It makes it a better travel partner and fewer things to carry. When the car seat doubles as a stroller bed, it also saves space in the car.
  • Never disregard the comfort factor of the car seat, or your baby will be fussing and crying the whole time you’re driving. The seats, the padded cushions for coziness, breathable fabric for the hot season, and the energy-absorbing foam liner that cushions the baby are some of the comfort features to look out for when buying the car seats.
