Graco produces some of the best car seats that are easy to install, have many safety features, occupy less space, and are long-lasting. The car seat maker has several 3-in-1 car seat options, including Graco Slimfit 3-In-1, Graco Extend2fit 3-In-1, and Graco Triride 3-In-1

Being a mother of three, I’m fully aware that changing car seats as your child grows can be quite a hassle. That’s why I am really excited to review the Graco 3-in-1 car seat that allows you to adjust your car seat between 3 modes: rear-facing harness (4-50 lb) to forward-facing harness (22-65 lb) to highback booster (40-100 lb). 

In this article, I will focus on the main benefits and features of Graco 3-in-1 car seats. I will also explain why you should buy a Graco 3-in-1 car seat. My review also compares some of the most popular 3-in-1 models. If you read to the end, you will see the answers to frequently asked questions about Graco 3-in-1 car seats.

Why Should You Buy Graco 3-In-1 Car Seat?

Graco 3-in-1 is ideal if you don’t want to constantly change car seats as your child grows. The Graco 3-in-1 range provides fantastic options, such as the Graco TriRide 3-in-1 Car Seat, allowing you to choose the perfect headrest height from 10 positions and adjust the seat to 6 recline positions for better installation. The LATCH system makes the installation easy. Its seat pads are comfortable and easy to clean via a washing machine. 

The Graco Slim Fit 3-in-1 model has unique, rotating cup holders that you can turn away and make the car seat 10% slimmer, saving up precious back seat space. The Extend2Fit model features a 4-position extension panel that provides up to 5” of extra rear-facing legroom, so your child can ride rear-facing comfortably and for longer. 

This is an excellent choice if you’re looking for a cost-effective, long-lasting car seat. The 3-in-1 car seats allow you to use them as booster seats, which is a great advantage that many other car seats do not possess.

The SlimFit 3-in-1 and TriRide 3-in-1 models are suitable for the following conditions:

  • For the rear-facing mode, the child must be 49” or less, 
    • If the child weighs 5-22 lb and is less than one year old, it must be rear-facing.
  • For the front-facing mode, the child must be 49” or less. 
    • If the child weighs 22-40 lb and can sit upright unassisted, it can be used forward-facing.
    • If the child weighs between 40 and 65 lb, then it should be used forward-facing
  • For the booster mode, the shoulder seat belt must be 43-57″ tall, and the child must be over four years old. 
    • You can use it as a booster mode if the child weighs between 40 and 65 lb. 
    • If the child is over 65 lb, it must be used in booster mode. 


The instructions for the Extend2Fit 3-in-1 model are slightly different:

  • The child can be 4 lb for the rear-facing mode compared to 5 lb on the other models.
  • The rear-facing mode should be used up to 50 lb compared to 40 lb on the other two.
  • The forward-facing mode should be used from 50-65 lb compared to 40-65 lb on the other two models.


What Does Graco 3-In-1 Come With?

Several features are present in Graco 3-in-1, along with accessories. The accessories include:

  • Harness covers: These make the harness straps more comfortable and prevent your child from getting irritated by them. While using, ensure that harness covers do not interfere with the placement of the chest clips at the armpit level. To remove them, simply undo the fastening strips and remove them. 
  • Infant body support: Use this if the shoulders are below the lowest harness setting. You should use it only in the rear-facing mode and not allow it to bunch or fold behind the child. 
  • Infant head support: The head support should be used only with the body support and only in the rear-facing mode. 


The three car seat models are slightly different in their width, height, depth, and weight:

Which One Should You Choose?

Considering the advantages and disadvantages, the SlimFit 3-in-1 model is the better choice. While it lacks some recline positions, and you can use it rear-facing for up to 40 lb only, it makes up by being lighter, slimmer, safer, sleeker, and cheaper than the Extend2Fit 3-in-1 model. 

However, if you prefer a model that you can use in rear-facing mode for longer, has more recline positions available, and the whole cushion is washable, then the Extend2Fit will be better. 


The Graco 3-in-1 is an excellent choice if you’re looking for a long-lasting car seat that will support your child as they grow. Its rear-facing and front-facing modes are pretty good, with great features and accessories. 

While I do not recommend using this car seat to be a booster seat, the booster mode is quite useful when transitioning your child to a dedicated booster seat. 

If you’re looking for a cost-effective and long-lasting option, the Graco 3-in-1 TriRide, available for $190 on Amazon, should satisfy all your needs. If you want a more compact, secure, and sleek design with rotating cup holders to save some space for the backseat, then the SlimFit 3-in-1 should be your go-to. In case you want to use the rear-facing mode for longer, then your choice should be the Extend2Fit 3-in-1 model. 

Regardless of whichever model you choose, each one has some great practical features that will more than satisfy you and your child. I recommend the Graco 3-in-1 products, and you should try them.
