What Should You Consider for When Purchasing the Best Lightweight Infant Car Seats? - Buyer's Guide

Some claim that there's no such thing as "the best infant car seat," but I disagree since it's subjective, and you'll find the best seat for your family. So, what should you know about the best infant car seat - the lightweight one?

  • It must FIT your baby correctly
  • It must MATCH with your motor vehicle
  • You can use it CORRECTLY all the time

1. FIT

The first point is that the seats must accommodate your newborn baby, and if you have a newborn infant, all infant car seats will fit.

However, the situation changes when they grow, and you have to choose those car seats from 4 to 35 lbs. of weight for children up to two-years-old. NOT ALL OF THEM might be lightweight, but they are excellent for infants/toddlers.


best lightest infant car seat

The second point refers to the fact that NOT all infant car seats fit your car seats.

Some brands, such as Evenflo, provide the space between the car seats and infant car seats, but not all others. You can avoid this when you install the infant car seats in the middle of the back seats but be careful with the LATCH system as it won't allow it.

However, almost all infant car seats have the built lock-offs; thus, you can correctly install them even with the LATCH attachments. Thus, both you and your little ones will ride comfortably, with enough space in the motor vehicle.


The final point refers to the common knowledge that you MUST know how to install your new lightweight infant car seats correctly and get them ready for your little ones.

The best place to do so is the car seat's manual. But many manuals contain additional critical information that you may or may not follow and get confused. In that case, you must contact the safety technician or instructor to help you in this process; otherwise, your little ones CANNOT use the car seats.

How Important is Infant Car Seats Weight? - Extra Information

There are different criteria to consider when selecting the best infant car seats. As you need to check the safety, security, stability, protection, and other factors, you mustn't forget the seat weight. You might not consider it essential, but I do, and let's see why.

Although it can be a deceptive factor, I consider it critical for various reasons:

top lightweight infant car seat
  • It's ideal if the infant car seats weigh around 10 pounds, and when you place infants into them, they add some pounds more; it's not a big deal. However, I have reviewed various car seats, and they vary in weight so that you can get them according to your needs. But when you put a growing child into a bulky car seat, you cannot carry them properly. That's why it's better to use strollers. Weight is a vital factor if you don't have a stroller and have to do all the jobs manually.
  • If you plan to start a journey by plane, you need to consider the weight of the infant car seats as well because the FAA approved car seats weigh around 15 pounds. There are some exceptions, but why would you complicate your situation? It's easier if you check the weight and get your best options. Not all seats can pass the airports, and that's why you need to consider their lightweight if you don't want to move around in problems.
  • If you get incredibly lightweight car seats (5 pounds, for instance), you have to check whether they go with or without the base. If they go without the base, you will have to take the additional weight of the base, the extra pounds of your little ones, and complicate the situation again. Thus, it's more comfortable to choose the more massive car seats with the base than the lighter car seats without one.
