Benefits to a Convertible Car Seat

Baby in a car seatA lightweight car seat has more benefits than just for carrying around.  You also need to ensure that you have a car seat for other forms of travel. For example, these kinds of seats are very much needed on plane rides and on long distance car rides. There are many unique benefits to buying a lightweight car seat!

  • They are essential for fitting easily into compact cars and not added a lot of extra weight and bulk to your car load
  • Great for families who share a car seat for multiple cars
  • Easier to transport on an off planes
  • Great when using the car seat to also transport small babies by hand or in a stroller
  • Helpful when taking inside for cleaning or repairs

Again, let us mention how important finding the best convertible car seat for travel is as well. We’re talking long distance travel either in the car or a plane. For example, many parents do not understand that car seats are not provided for air travel, so it’s important that you bring your own.

This can come as a shock to some people who have bulky, heavy car seats. You certainly don’t want to have to lug a heavy seat on and off a plane. And additionally, if your baby is seated next to someone else, a large car seat could cause problems. This is yet another reason to opt for a lightweight car seat that is also compact.

If you still have questions about the best travel car seat or lightest convertible car seat, we’ve got the answers for you! Below, you will find the most frequently asked questions that concern lightweight car seats, shopping for them and using them in your vehicles.

Q: Isn’t a lighter weight car seat going to be flimsy and easily breakable?

A: This is actually a myth. A lightweight car seat is actually a great seat to use in any car for any level of safety. There’s no need to worry about it being too flimsy or unusable because as long as you buckle it into the LATCH system properly, it will be fine. Lightweight car seats have the false reputation of being too light so that they are easily breakable.

What the term lightweight is actually referring to is the fact that the unit does not weigh as much as many of the other, more bulky units. The products used to create the lightweight seats are quality made. They are just lighter and easier to maneuver, which makes them great seats.

Q: How do you know if a car seat will fit into your car?

A: It can be difficult to know the exact size and shape of a given car seat before you even buy it and get it home. This is often especially true when we are dealing with car seats on the internet. Fortunately, you already know that all of the car seats mentioned here are especially lightweight, so you already know that they aren’t too bulky either.

In addition, when you are shopping online for a lightweight car seat, you can always look at the dimensions listed under specs. You can ask other people who have purchased the item as well. Many people on Amazon answer questions readily, and they are happy to offer their advice and input about how the seat might fit in a variety of different cars.

Q: What’s the deal with forward and rear facing car seats? Which way do I face my child?

A: Safety experts say that it is safest to have your child facing the rear of the car. This is because babies have heavy heads, but their necks are very fragile, and the bones in their necks are soft with stretchy ligaments as well. This means that if there is a crash at the front of the car, then their bodies will be kept in the comfort of the safety seat, but their heads will fly forward. It is important to keep in mind that crashes in the front of the car are the most common.

On the other hand, when a small infant or toddler with a heavy head is facing the rear of the car in a crash, their bodies will be protected with the safety harnesses, and their heads will also not be allowed to fly forward.

You need to wait a significant amount of time until you will be able to face your child to the front of the car. This will vary based on how old, big and tall your child is. This change will also vary based on the different car seats that you choose. Each car seat will have a unique stipulation on it that tells you when you can move your child to a seat facing the front. Most of this will matter on the weight of your child, but you should also aim to wait until your child is at least 2 years old before turning them toward the front.

Q: Will a lightweight car seat be sturdy and safe enough if we were to get into a crash?

A: Yes, a lightweight car seat will definitely be able to hold up perfectly fine if you get into an accident or collision. Many parents decide to purchase bulky, heavy car seats because they feel they’re more durable and will help keep their children safer. In some cases, this may be true. For example, if you use a lightweight car seat but do not latch it in properly to the seat bed or you don’t belt your child in the right way, the lightweight car seat may end up flying up in the event of a crash whereas a heavy seat might stay put longer because of its weight. But this is not the fault of the car seat.

Q: Do lightweight car seats work on airplanes? Do I have to have a car seat on an airplane?

A: Yes, lightweight car seats do function great on airplanes, and yes, if you are planning a flight with your child, you should plan on bringing a car seat. Remember, lightweight car seats are just like regular car seats. They just weigh less. In fact, lightweight car seats are much easier to use on an airplane because they weigh less. They will be easier to transport from your car to the plane and from the plane to your destination.

As for the necessity of car seats on planes, according to some safety regulations, the Federal Aviation Administration does not necessarily require 100 percent that car seats be used for babies and children who are flying, but most safety and plane travel experts agree that using a safety seat for small children on airplanes is the best idea. If you don’t use a seat, you will need to hold your baby, and this could be risky for both you and your child. Aside from that, the airline may not let you fly if you insist on holding your child. This depends on the airline and their regulations. It also depends on how old and how big your baby is.

Q: How do you keep a child warm in their convertible car seat? Can you keep their coat on when they’re strapped in?

A: This gets quite tricky because having your child in a coat while they are strapped into their car seat can present numerous problems. First, their coat may get snagged and cause latching problems. Sometimes, you can’t even see the snag until it’s too late. Furthermore, having extra clothing and padding on by way of sweaters, scarves and coats creates extra compression on your child’s chest.

To solve this problem, the best solution is to make sure the car itself has warmed up before putting your child inside. Do not put a bulky coat on along with them. If you have to use a coat, make sure it is a thin one. In addition, you might think about using a fleece blanket over top of your child for added warmth and comfort.

Q: Can infants and toddlers sit in the front seat as long as they are in a car seat?

A: No, infants and toddlers cannot sit in the front seat at all. Each state has their own laws about how old, heavy and tall kids need to be to sit in the front, but basically, kids need to be at least 4 feet 9 inches before they can sit in the front seat. They should also be at least 80 pounds in weight and at least 12 years old. Again, check with your unique state’s guidelines.

Why can’t kids sit in the front seat when they are small? It has to do with the airbags. Small children do not have strong enough necks to withstand the impact of an airbag in the event of a crash. As a result, they might have a spinal injury if they sit in the front and the airbag deploys on them.

Q: Where do I seat my child if I drive a pickup truck?

A: If you drive a pickup truck but still want to ride along with your child, you’ll need to look at the unique model of your pickup to decide where exactly to seat your child. Some pickup trucks have backseats in them, but generally speaking, these areas are way too small to seat a child. This is a risky situation to put your child in as many safety tests have confirmed. Some back seats do face front and are big enough for a car seat. If this is the case, just check with the truck’s manual to make sure that a car seat will be okay in the front. If you absolutely have to strap your child into a seat in the front of your pickup truck, make sure that you turn the airbag off for the passenger’s side of the car.

The best solution to this dilemma is of course to find a better vehicle for transporting your child around. Pickup trucks are not generally safe for children who are not yet old enough to sit in the front seat.

A Summary and How to Make Your Final Decision on a Lightweight Car Seat

A family driving a car on the highwayWhen you’re trying to concentrate on the road and you have a child in the back seat, you absolutely need them to be comfortable and happy.
