Finding a car seat that checks all the boxes such as car seat safety, comfort and versatility can be a tough task, especially for parents who are constantly trying to find the best products for their babies.

When you have an infant, you need an infant car seat, then within a year or so you’ll need to upgrade to a convertible car seat and eventually slide into a booster seat. Over time, that ends up being a lot of car seats to purchase.

There is a better way, and we want to tell you all about the all in one car seats that have excellent features that you will love.

While there are so many benefits of investing in a convertible car seat for your baby and toddler the all in one car seat option can help solve the booster seat issue later on.

When you are looking for an all in one car seat, you’re going to want to look at the top brands that offer a seat that will fit your life for the long haul.

We will take a look at cost, quality, comfort and safety when presenting you with all the information you need in order to make the best purchasing decision for your all in one car seat.

It is important to never purchase a used car seat. Even if it means you’re going to save money, you do not know the history of the seat. A car accident or even exposure to the sun can change the safety rating of a seat. If a seat doesn’t show signs of damage it does not mean it was not in any sort of compromised setting. It is always important to purchase a car seat that is new so you can keep up with recalls on products and other safety news.

Guide To Buying A Car Seat

What Is An All In One Car Seat?

An all in one car seat is a seat that you can use from infancy to big kid years. Many all in one car seats can last up to 10 years, which means you’re getting the best bang for your buck with one of these.

Instead of purchasing 3-4 car seats in the lifespan of your child car seat required days, you’re only going to buy one seat.

All in one car seats go from rear facing, to forward facing, to booster seats and some even go to the backless booster seat styles.

Even though it may seem like an all in one car seat is expensive right now, it is actually the cheaper way to go when you think about the other seats you will need to purchase in your baby’s lifespan.

Benefits Of An All In One Car Seat

The biggest benefit of an all in one car seat is the convenience and cost factor.

It is more economical to buy an all in one car seat that may be more expensive at first than to purchase 3-4 car seats for one child across 10 years.

You also eliminate the need to research additional car seats as your child enters the different car seat stages throughout the years. It’s kind of a one and done deal that lasts 10 years.

The all in one car seats have higher weight limits than convertible seats, which makes sense as they are supposed to be used for years longer than a traditional convertible.

Another benefit of having an all in one car seat is the ability to pass down the seat to siblings. Because most all in one seats do last 10 years, you;ll be able to use it with multiple children.

Disadvantages Of An All In One Car Seat

As there are benefits to an all in one, there are also some disadvantages and we didn’t want to leave you without knowing about them.

One of the main concerns about purchasing a car seat that is supposed to last 10 years is the durability concern. Will the seat hold up after 10 years? There will be spills, tears and other wear that will occur, and while the seats we chose are amazing in quality and are built to last, that many years on a piece of baby equipment will still be hard on the car seat.

Another disadvantage of an all in one car seat is the heaviness and non-portability of the seat. It’s kind of an install once and leave it until the next stage is required type design. You won’t be able to put this car seat into a stroller such as an infant style that clicks into the stroller with ease. You’ll have to take your infant out of the stroller and into the car seat each time you’re transferring them in and out of the car. This could mean waking the baby up, which can be cumbersome.

Many times, the all in one car seat is often bulkier and bigger than a traditional car seat, so if you have a smaller vehicle, it might not be the best idea to purchase such a bulky seat.

Different Types Of Car Seats

There are a few different types of car seats to choose from, besides the all in one option:

Infant car seat: Infant car seats are made especially for newborns and babies and can typically support a child from 4 -35 pounds. A lot of times this is a car seat that comes with a base and can be removed to be carried or clipped into a travel system stroller. These seats can only be installed rear-facing as this is the law for newborns and will help absorb impact in an accident. You can graduate baby to the next car seat once they reach the weight limit or if their head begins to be less than an inch away from the top of the car seat.

Convertible Car Seat: A convertible seat is a car seat that grows with your little one. They are often used when your child grows out of the infant seat and is still too young for the booster seat. A convertible seat typically supports a child from 22-35 pounds and are usually more bulky and heavy in design. Generally, your child can be placed forward-facing around age 2, or when they hit the manufacturer’s guidelines. When your child outgrows the convertible seat, they can go into a booster seat.

Booster Seat: A booster seat helps your child sit properly with a seat belt after they exceed the weight limits of the convertible seat. They need to be able to ride in a calm and respectful manner and follow the car rules before they can sit in the booster seat. Booster seats are generally used when children reach 4 feet or are 8-12 years old. When the child has outgrown the booster, they can ride in an adult seat.

When Do You Need Car Seat

You’re going to need a car seat installed properly in your car before your baby is born. The hospital will not let you leave without a car seat for your newborn.

Features To Consider

Because an all in one car seat can work from birth to seat belt age, you’re going to want to look for a unit that is high quality. But other than quality, what other features should you be focusing on when you are thinking about an all in one car seat?

We made life easier for you and compiled a list of important features for you to look for when considering an all in one car seat.

Ease of use: A high quality car seat should be easy to install and not leave you confused about the installation process.

The LATCH connectors should be simple to push in and should not require you to get into a battle of tug of war with the seat belt. The seat should come equipped with a level indicator to help you ensure you are installing the seat at the best angle.

Profile: When shopping for an all in one car seat, you’re going to want to look for one that has a sleeker, more narrow profile that allows you to maximize backseat space.

Performance: A high quality all in one car seat should have padding along the head rest area and the bottom of the seat for ultimate comfort. The harness and headrest should have adjustment options that are easy to use.

When a unit is extra tall and has a calf rest, the baby can sit rear facing for a longer period of time and allow extra legroom for the child to stretch their legs.

Because kids tend to get car sick, have diaper blowouts and are generally messy, it’s a good idea to be able to get a car seat with an easy to remove and wash cover. Sometimes you may want to get a new cover altogether because 10 years is a long time for fabric is used on a daily basis.

Safety: Car seats have to be fully loaded with all the latest standard safety features and you should not add or take anything away from the seat which could compromise that safety. Some car seats offer a side impact protection or uniquely designed cushions to protect the head. An all in one car seat that has a steel frame, an impact-absorbing base, shock-absorbing foam and side-impact protection can really minimize the injuries your child could sustain in a collision.
