The Skinny

The Graco SlimFit All-in-One is a convertible car seat included in our best convertible car seat review. It is designed for use from infant to toddlerhood and as a booster. This seat eas easy to install using LATCH during testing, and we think most of the features are easier to use than some of the competition. It earned average results for crash testing with unremarkable sensor results compared to the competition. Overall, this seat isn't remarkable, and while not terrible, we think there are better choices, with higher crash test analysis results in the same price range, like the Graco Extend2Fit.

Our Analysis and Test Results

The Graco we know and love began in 1953 after the metal fabrication company hired an engineer to design something new. Rex Thomas and David Saint were inspired by a coworker's story of soothing a baby using an outdoor glider. Their unique baby swing design launched Graco into the baby product world, selling millions in a short time. Graco continues to create baby gear, including strollers, some family favorite car seats, swings, and more.

Crash Test


The Graco SlimFit All-in-One crash test analysis score is just below the average. While it passes the federal safety standards, it does not appear to offer an additional margin of protection compared to the competition, in our opinion.

The HIC result for this Graco (chart above) is 320, where the maximum allowed is 1000, and a lower number is better. This result is fairly impressive on its own as it is significantly below the max allowed. Still, when compared to the competition where several seats had results below 300 and the best being a 186 for the Britax Allegiance, you can see how it didn't measure up to the competition.

The Slim's chest sensor result (chart above) is 43, where the maximum allowed is 60. Once again, it easily passes the federal standard, and viewed on its own, it feels like a good score. However, the lowest result, and therefore the best in this group, is a 34 earned by the Clek Foonf.

The best-combined results for HIC and chest sensors belong to the Graco Extend2Fit.

Ease of Install - LATCH


The SlimFit All-in-One has push connect LATCH anchors we like better than clip style, and it earned its best installation score using LATCH. Attaching the anchors is easy, and tightening the strap wasn't a hassle. Loosening the strap is also simple, and we didn't need extra strength to install or remove the seat as we did with some of the competition.

We were able to get a more secure feeling fit with the seat in the rear-facing position. Still, both were stable enough that we didn't experience significant movement when properly installed. Whether you install using LATCH or the vehicle belt, you need to move some padding around to get the straps in the right location. This isn't hard but is more convoluted than some of the more straightforward competition. An easy-to-read ball level indicator ensures the seat is installed at the correct angle.

Ease of Install - Belt


Installing the Graco SlimFit All-in-One using the vehicle belt is somewhat harder than the LATCH, but it only lost a point for this method. The padding on the seat and seatback needs to be moved to thread the belt, and those with larger hands are going to struggle with the smaller belt path openings. Potentially making this installation more challenging for some dads.

The forward-facing configuration for the SlimFit includes running the belt through the pathway on the back of the seat.

Rear-facing shoulder/lap belt installation is easier and feels more secure in our tests than front-facing, where we struggled to get the vehicle belt tight enough to hold the seat in one position. However, when installed rear-facing, the entire seat was able to tip back toward the vehicle seat.

Ease of Use


The SlimFit All-in-One is easier to use than much of the competition in our best convertible car seat review, with a straightforward design and nothing fancy to figure out.

Harness


The buckle on this seat is similar to other Graco buckles, and while easier to depress than some previous versions, it is still not as nice as some contenders. The chest clip isn't as intuitive as some of the competition, and while it works fine, it isn't our favorite.

The harness on the SlimFit All-in-One is super easy to adjust with a non-rethread style that operates smoothly by squeezing the lever at the top and sliding the entire headrest. The shoulder straps have 10 possible height positions for a good fit, and the crotch strap has three.

The SlimFit user manual slides into the back of the seat and is easy to access even when the seat is installed.

LATCH Storage


The LATCH anchors attach on the Slim high on the sides of the shell (above left) or under the front edge of the seat, and the tether clips high on the side—both locations sort of fail at keeping the straps and anchors out of the way of passengers. Not only are they uninspired, but they aren't very functional. The user manual stows in a pocket on the seat's back (above right) within easy access even if the seat is installed.

Cover


The Graco SlimFit All-in-One cover is average for ease of removal. It can be a little tricky under the seat bottom, but it is manageable. The cover is machine washable but must be line dried. This process is probably best done overnight or when you know, you won't need the seat as drying times will vary based on your local climate.

Comfort/Quality


The Graco SlimFit All-in-One is a good-looking seat at first blush, but when you dive deeper, it isn't a standout in this metric compared to the competition. The overall padded is decent and supportive, but it isn't great and won't offer long-term comfort on road trips cross country. It also comes with a collapsible cup holder.

The fabric is two styles with a tighter weave on the seat's body and a strange mesh style material on the edges. Neither is particularly skin-friendly, and gunk can easily collect in the mesh weave. The outer shell is mostly self-contained, and it looks good compared to other seats in the same price range. The bottom is smooth and shouldn't cause damage to vehicle seats. The overall fit and finish are nice for a Graco mid-range product, but overall it struggles to keep up with the options that give more attention to padding and fabric for comfort.

While the SlimFit is fairly lightweight for the group, at almost 19 lbs it is still probably too heavy to carry for long periods of time.

Weight


While weight for a convertible seat may not be as crucial as it is for an infant carrier, it can still factor into decision-making if you travel or need to carry it. The Graco SlimFit All-in-One is 18.6 lbs, which is relatively lightweight for this group, but some weigh significantly less and score higher or have better crash test sensor readings.

Should You Buy the Graco SlimFit All-in-One ?


While we understand the appeal of an all-in-one product, as it can save you money and potential time, we do not think this is a good idea, nor is this seat a great choice. Because safety seats across types are designed with a specific size and developmental level in mind, we believe it is safer to use an infant seat for babies under nine months and a convertible seat for those who have outgrown their infant carrier. Even if you aren't considering this car set as an all-in-one option, it still didn't perform as well as the competition. We think better options are available with higher individual scores in almost every metric. We aren't even sure why it is called the "Slimfit" as it is 19 inches and only slightly smaller than a competing Graco but definitely bigger than options like the Clek Foonf, which are 17 inches.

What Other Convertible Car Seat Should You Consider?


We think the Graco Extend2Fit is the better Graco to buy. This seat has one of the best scores for crash tests, and it is virtually the same size and price as the Slimfit. We prefer the Extend2Fit for its longer lifespan of 50 lbs, and even though you'll need to buy a separate booster, the price is low enough that you can cross that brings when it is safer to get there without your budget taking a big hit. We believe that most families will enjoy the Extend2Fit.
