Graco TriRide VS SlimFit Car Seat – Comprehensive Comparison

What is the Difference Between Graco Triride and Slimfit?

The Graco Triride, a more budget-friendly model, released in 2021, and the Graco Slimfit are both 3-in-1 convertible car seats that can be used in rear-facing, forward-facing, and high-back booster seat modes over ten years of its lifespan.

Despite being similar in seat modes, both models (Graco Triride vs Slimfit) have distinct differences in specs, dimensions, and features.

The TriRide 3-in-1 is relatively lighter in weight (17.2 lbs < 19.47 lbs.) than the SlimFit 3-in-1 and is more budget-friendly but lacks some essential “ease-of-use” features when compared with the Slimfit.

On the other hand, the SlimFit3 LX, as the name implies, is very slim (16.7 inches wide) and will fit three perfectly across the back seat of many vehicle models. However, both seats are compatible with mid-size and small cars.

The Triride comes as a single model offering all its features in one single product line, unlike the SlimFit, which comes in two product lines – the SlimFit 3 in 1 and the SlimFit3 LX 3 in 1.

Detail Analysis of Both Seats – SlimFit vs TriRide – The Winner?

graco triride vs slimfit

From the Graco Triride vs Graco Slimfit specs table and other comparison tables above, you’d have seen all the similarities and differences between both seats. This can now help you make a buying decision.

As much as they share nearly the same similarities in specifications, they differ closely.

However, which car seat wins across the board?

Determining this will be more of a personal choice as each difference is not so significant when your buying decision is based on budget. Nonetheless, each seat is as good as the standard requires.

The major differences between the Triride vs Slimfit are in the product dimensions and weight.

  1. Product dimension – the SlimFit3 LX 3-in-1 (16.7″) – is slimmer than the Triride (19″) by about 3 inches, while the SlimFit (19.9″) is just about wider than the Triride by less than an inch (0.9″). Nonetheless, both seats will fit nicely in mid-size vehicles. On the other hand, the SlimFit3 LX will fit three across in most small cars.
  2. Product weight – the TriRide 3-in-1 weighs lesser than the SlimFit. At 17.2 lbs., the TriRide is relatively lightweight than the SlimFit, which weighs 19.47 lbs. and 19.2 lbs. (3-in-1 and LX 3-in-1, respectively). Notwithstanding, these weight differences are negligible when compared to other convertible car seats and can be easily switched between cars

The comparison here comes at a close call, with the Slimfit winning in one and Triride negligibly on the other.

Specification Comparison

All about the dimensions, weight, seat modes, recommended weight, and height limits are highlighted here.

Product Weight, Dimension

On the aspect of dimension, the SlimFit3 LX is the slimmest of the three seats compared in this article.

This should influence your decision if you need three seats across in your vehicle, be it small or mid-size.

However, if you are limited by budget and still need three seats, you should go for the two triride and one slimfit3 lx.

On this, the SlimFit3 takes the win.

Seat Modes, Weight, and Height Limits

Both seats have the same three seat modes, recommended weight, and height limits.

Therefore, no seat takes the win here.

Features Comparison

At the beginning of this article, I mentioned that the Triride is more budget-friendly but lacks some essential “ease-of-use” features compared to the Slimfit.

This is where other significant differences lie, which may influence your buying decision.

Safety Features

As a constant reference in every article about car seats, all child safety restraints sold in the market and not recalled are safe.

This is because every car seat sold in the US market is made to pass very stringent federal safety standards.

Nevertheless, many car seat manufacturers go over and above to improve the safety features of their models.

The Triride and Slimfit, being products of the same brand, are made with the same high safety standards as all their car seats, irrespective of other features and pricing. The Graco Protect Plus engineering is a safety standard across all Graco car seats, including Graco’s RollSafe™ Testing, based on the European rollover testing procedure.

Based on this, there is no winner.

The common safety features in both seats are:

  • Side Impact Protection,
  • 5-Point Harness System
  • Exceeds Federal Safety Standards
  • Rigorously Crash Tested (front, rear, side, and rollover crashes)
  • IIHS Rating – BEST Best for booster seat mode in both seats

Installation Features

This is one feature where the Graco Slimfit vs Triride seats differ.

What makes a car seat serve its purpose optimally is how it is installed in a vehicle.

While some parents may overlook an unsecured installation thinking a car seat has been installed correctly, it may be a result of a difficult installation.

The SlimFit car seat features the Graco inRight LATCH system, which makes installation with the LATCH/ISOFIX system very easy. The Triride, on the other hand, features the conventional J-hook LATCH system.

For the seat belt installation, the SlimFit3 LX features the integrated belt lock-off system. In comparison, the others use the standard seat belt method.

Notwithstanding, the standard J-hook LATCH and seat belt methods (only one method must be used for installation) can get the seat securely installed.

However, when it comes to convenience, SlimFit wins here.

Ease-of-Use Features

Other ease-of-use features such as harness holders, recline level indicators, and recline positions make other differences in both seats, while other features are available in both.

Harness Holder

The Triride 3-in-1  safety seat lacks the harness holder, a feature that makes getting your child out of the car seat somewhat easier.

The harness holder holds back the harnesses while getting your child out of the car seat.

The SlimFit3 LX has this feature.

Recline Positions

The Triride 3-in-1 seat has more recline positions than the SlimFit 3-in-1; the Triride allows reclining in six positions, while the Slimfit has four positions.

This means the Triride will fit better in more vehicles and provide more comfort when rear-facing (three positions in triride, two in slimfit).

Level Indicator

While this is a miscellaneous feature that shouldn’t influence your buying decision, it is worth mentioning to be aware about it.

The SlimFit comes with a bubble indicator which is easier to read than the ball indicator in the Triride during installation.

Other similar features in both seats include;

  • Harness storage
  • Headrest adjustment – 10 positions
  • Harness adjustment
  • No rethreading of the harness required
  • Easy to remove and machine washable car seat cover
  • Soft plush fabric
  • Two removable newborn inserts
  • Two removable cups (slimfit’s is rotatable)

Comfortability of a Child

Both seats are comfortable for a child.

One of the standard feature across Graco car seat models is the use of soft fabrics which give a child that cozy feel.

However, the SlimFit3 LX has breathable mesh airflow channels that provide improved ventilation for a child. This is an advantage during the summer when you need to keep baby cool in a car seat.


Due to their reinforced steel frame structure, Graco car seats are made to last ten years from the date of manufacture.

Both seats will expire after ten years.

FAA Approved

The Slimfit and Triride child seats are approved for use on airplanes as rear- or forward-facing.

Their labels are found on the side of either seat.

Final Thoughts and Recommendations

Choosing between these two seats may be a close call because of their similar features.

However, one major factor that should influence your decision is your budget.

The Graco TriRide 3-in-1 car seat is budget-friendly while packing as many features as a child restraint should have without compromising safety and comfort.

The Graco SlimFit only has a comparative advantage when it comes to dimension, and that’s restricted to the SlimFit3 LX, which is the most expensive of these seats.


  1. If you need three car seats across and can afford the latter, then you are good to go. But if you are constraint by budget, here’s my recommendation:
    • Buy two Triride seats and a SlimFit3 LX. This gives you a total width of 54.7″, which is just about the interior distance, door to door (shoulder room) of most compact and mid-size vehicles. The Slimfit3 should be in the middle, rear-facing, while the Triride on the sides, forward-facing.
  2. If you often switch between cars, you may want to be biased in your choice. The TriRide saves you some energy lifting the seat often from car to car, even though it’s barely 3 lbs less.
  3. If you are a new parent getting a car seat for the first time, you should consider the SlimFit car seat. This is because of the more ease-of-use features it is packed with, such as the installation features, level indicator, harness holder, breathable mesh airflow, compatibility with smaller cars, and more color choices.

Beyond these, you can make your decision based on your personal preference, albeit understanding the comparison of the Graco Slimfit 3-in-1 vs Triride 3-in-1 car seats.
