Cosco Mighty Fit 65 Review Facts

For some parents, finding a car seat for their child that will last them for a long time can be quite the struggle. And with most car seats, even if you do find one that your child will be able to use as they grow as a toddler, you’re most likely going to still need to find a booster seat. However, being able to find a seat that is convertible and that can be used when your child is a baby and when they become a toddler will help to make things easier for you.

The Cosco Mighty Fit 65 is a convertible car seat that a lot of parents liked for the fact that they were able to get a lot of use out of it from when their child was a newborn to when they were around 65 pounds. This means that you won’t have to spend too much on multiple car seats throughout the course of your child’s young life. And besides that, there are many other features that parents appreciated about this product, such as the fact that it can be used on airplanes and that it has all the safety features needed (and more) in order to keep your mind at rest.

The seat is also small enough for you to be able to fit three of them across the back seat of your car if you have more than one child. This is a feature that parents who have larger families appreciate. It also can be adjusted for your child as they grow bigger to further ensure their comfort, and a big plus is that you will be able to throw the padding in the washing machine when your child has a spill.

Basic Features

One of the most important parts of discussing any car seat’s features is discussing the seat’s size and capacity. Most parents are on the hunt for something that will be able to last them for a very long time so they won’t have to worry about making sure their child gets used to another car seat and so that they don’t have to spend money on new car seats all the time.

This is why convertible car seats have been growing in popularity; they can be used both for newborns and for toddlers and can be used in both positions. The seat can be rear-facing when your child weighs between 5 and 40 pounds. When your child is between 22 and 65 pounds, it can be forward-facing. Depending on your child’s body type, you’ll easily be able to get quite a lot of use out of this product.

Another feature that will make things a lot easier for parents is the fact that the padding on this seat can be put into the washing machine. This is important because it is inevitable that your child will have a spill or an accident at some point, and simply being able to throw the padding from the car seat into the washing machine will make things a lot easier for you. It can also be thrown into the dryer afterward for a quick dry.

And finally, a feature that has captivated many parents was the fact that this product is extremely affordable. You won’t have to worry about breaking the bank or spending more than your budget allows with this one. And despite the fact that it is well below $100, there were quite a lot of parents who were pleased with this product and did not experience any issues with it.

Advanced Features

Some of the more advanced features of this product have to do with its size and safety features.

As we mentioned, the seat can be used in both the rear and forward-facing positions and it can also be used from when your child is a newborn to when they are well into their toddler years. However, with that being said, the seat is fairly small and won’t feel bulky in your car. It can be used on airplanes and it won’t affect the person who is sitting in the passenger seat too badly when in the rear-facing position. We will talk more about this product’s size in the following section.

And perhaps the most important part of any car seat is its safety features. You need to be able to ensure that your child is safe at all times. And while many of these features have become fairly standard for car seats nowadays, they are certainly important. You will have protection on the sides in the case of impact so that your child won’t accidentally hit their heads badly, and there is also a 5-point harness that can be easily adjusted as your child gets bigger.


We already mentioned that the size of this car seat is one of its biggest sellers. It’s key to have a car seat that is big enough to be able to accommodate a child as they get bigger, but many parents also want to be able to have a car seat that can fit in their cars and that won’t be too bulky. The dimensions of this product are 17 x 22 x 23.5 inches, which makes it rather small in comparison to many of its counterparts.

There were parents who said that the seat fit easily into their smaller cars, making it a great option for anyone who drives a sedan or just a smaller car in general and may not be able to afford a larger car. Plus, if you are a family that tends to travel on airplanes a lot, this seat has been approved for use on aircraft, which further makes it convenient and a good option for many parents.

And finally, if you happen to have several children who need to use car seats, the great thing is that you can fit three of these across the backseat of your car, so you won’t have to try and find something else that will be able to accommodate all of your children. Plus, when in the rear-facing position, the car seat is not going to cause any inconvenience to the person sitting in the passenger seat.

Overall, the size of this product makes it a highly convenient and versatile option for any family.

Ease of Use

There were pretty mixed reviews when it came to how easy this car seat was to install, especially in the rear-facing position. It’s marketed as being an easy-to-assemble product and there were plenty of parents who said that they never experienced any difficulties. However, the fact that there were parents who did and who said that it was nearly impossible to be able to install the seat into their car (especially those who were using it in the rear-facing position) makes it important to mention in this review.


There do not seem to be any accessories that come with this product. However, you can choose to purchase it in three different colors- onyx, heather navy, and pink.


Safety is most important when it comes to car seats. This one is definitely not lacking in that department. It has passed every necessary safety and crash test to fit US standards, and besides that, it has important features that will guarantee your child’s safety. The 5-point harness and the extra padding for impact protection will help to ensure that your child is secure at all times.


Considering the fact that you will be able to use this product from when your child is a newborn to when they are a toddler, it naturally has many mechanisms to ensure that you will be able to adjust its size as your child gets bigger. The seat can be used in the forward-facing position when your child gets big enough, and you will also be able to adjust the harness accordingly.


Many parents nowadays are looking for car seats that are lightweight and easy to maneuver. They tend to travel more often and don’t want to have something that will prove to be a detriment to their ability to do so. This makes heavier car seats less impressive because they aren’t easy to carry around. However, this Cosco car seat only weighs 14 pounds, making it one of the lightest seats on the market. You’ll easily be able to carry your child around in this and it will be easy to move around.


One of the main features that many people appreciated about this car seat is the fact that it comes at an affordable price. Where once upon a time, you were required to spend close to $300 to buy a car seat, that is no longer the case here. That is extremely convenient for many families who simply cannot afford to spend that kind of money on a seat. So, the fact that this Cosco product is available for less than $100- it retails for roughly $67 on Amazon- makes it an attractive option for many families.

Plus, the fact that it’s convertible means that you will be getting a lot more use out of it since it can be used from when your child is an infant to when they are a toddler (and even older). This means that you’ll be saving a lot of money in the long run. And even if you need to purchase more than one car seat, you still won’t be spending the amount that you might have to spend on others.
