Graco SlimFit Car Seat Reviews [The Best for Your Little Ones?]

slim car seats on the market

If you are looking for ways to fit your children in your car without compromising on either comfort or safety, take a look at our assessment of the extraordinary Graco SlimFit Car Seat Reviews.

Space seems to be an ongoing problem for many parents; if your family is expanding, you know what we are talking about. Even though the modern world we live in has us buying all sorts of stuff that we need and don't need, even the essentials sometimes present an issue.

Lack of space can indeed be problematic, especially if you need more room in your car. There is a solution, though; if you wish to learn about it, keep reading - Graco Slim Fit Car Seat reviews are here to help you out.

One of the first things we buy when we're expecting a child is a car seat; it is a true necessity. If our car isn't particularly small, we pick a car seat based on safety, comfort, and price. However, once our family starts getting bigger and we start having trouble fitting multiple children in the back seat of our car, we realize that we should have bought smaller or more compact car seats.

Truth be told, there weren't many slim car seats on the market until a couple of years back when manufacturers finally decided to introduce narrow options. It doesn't come as a surprise that these models quickly became a hit among buyers.

If we were to ask a group of parents whether they would benefit from additional space in their car, we are sure that the vast majority would say "yes" and ask us where they could find such car seats.

The Graco SlimFit Car Seat will save you space in the back seat while providing enough room for your child to grow. This all-in-one seat will grow together with your little one from 5 lb to 100 lb. It can be rear-facing (5-40 lb), forward-facing (22-65 lb), and it can also function as a belt-positioning booster (30-100 lb).

Moreover, the seat features the Simply Safe Adjust Harness System which makes adjusting the headrest and harness at the same time and accommodating your growing child rather easy.

The one-of-a-kind rotating cup holders can rotate and thus provide an additional 10% of space.

Also, there are four recline positions which will help your child feel comfortable even during long rides. Furthermore, the InRight LATCH system makes the installation simple and quick. Lastly, the Graco SlimFit has been side-impact tested and SafeSeat Engineered, so you needn't worry about safety - your child is in best "hands".

Hygiene is one of the top priorities for parents, especially during hot summer months. Thus, we were happy to learn that the seat cover on the Graco SlimFit is easily accessible, and it can be washed without removing the harness. Also, the seat cushion is machine-washable, and all plastic and metal parts can be cleaned with cool water and mild soap.

Apart from having all the above-mentioned impressive features, the Graco SlimFit comes in a sleek, space-saving design, which is always a plus. A car seat has to be safe and comfortable, but we love when it is aesthetically pleasing as well.

Graco SlimFit Installation

The installation was pretty straightforward, which didn't surprise us - most Graco models are easy to install. The instructions provided were fairly easy to follow.

Moreover, the SlimFit features premium push-on LATCH connectors, which made the installation very easy. In addition, we found that both the handy tab and the belt path are easy to access.

What's more, we tried installing the SlimFit in the center position (which is the safest place in the car), and we can say that it definitely fits well next to other car seats.

However, other seats shouldn't be too wide in order for everyone to be comfortable.

Additional Options

headrest pillow which is great for sleeping

In order to provide a better fit for small babies, the SlimFit has a removable body support. If your child's shoulders are below the lowest harness setting, then the support is required; in other cases, it is optional.

Harness strap covers and a removable headrest pillow are also at your child's disposal (they are optional). In our experience, the headrest pillow proved to be great for sleeping.

When it comes to the booster mode, we do wish that the belt was a little lower and that there was slightly more wiggle room.

Also, the buckle was a bit difficult to operate, and we believe that most children won't be able to buckle themselves.

Pros and Cons

After carefully going over all features and specifications, and after having conducted multiple tests and try-outs, we have come to the end of our Graco Slim Fit Car Seat Reviews. Before the final verdict, let's take a look at the pros and cons list.


  • Space-saving
  • Suitable for children from 5 lb to 100 lb
  • Rotating cup holders
  • 4 recline positions
  • Easy to install
  • Safe for your child
  • Easy to clean
  • Sleek and modern


  • In order to be properly installed next to another seat, that seat shouldn't be too wide

Graco SlimFit vs. Milestone

The Graco Milestone and the SlimFit have a lot in common. In terms of their features, these two car seats are almost identical. We had tested and used the Milestone for quite some time, and we have to admit that it was one of our top contenders. So, when Graco introduced a narrower option, we wanted to see if we could love it more than the Milestone. We'll be honest - we had our doubts, but we can now say that we do love the SlimFit version a bit more.

It's also important to note that switching between modes on the SlimFit is easy and quick, just like on the Milestone, which we enjoyed using.

Final Verdict

With an abundance of useful and safe features, and in spite of the few minor but not that important drawbacks, this model should definitely be one of your top picks, especially if you have two or more children and you don't have ample space in your car. In our humble opinion, Graco SlimFit deserves 4.5 stars out of five.
