Design and Build Quality

Both the Safety 1st Grow and Go and Graco Extend2Fit are durable and comfortable car seats.

The Safety 1st Grow and Go and Graco Extend2Fit are bulky car seats.

As expected, the Safety 1st and Graco 3-in-1 car seats emphasize safety and comfort. The Grow and Go and the Extend2Fit are both made from steel-reinforced frames for durability. These convertible car seats also feature thick, impact-absorbing foam pads for extra cushion and support. The pads are removable and are machine-washable, too. On either side of these seats, you also get two cup holders โ€” something that will come in handy as your child grows.

Now, the Grow and Go car seat is slimmer and more compact than the Extend2 Fit. This translates to a slightly more lightweight and portable model, too. Because of their sizes, however, these car seats will not double as carriers. You can get Safety 1st’s Grow and Go in 9 different colors, while Graco’s Extend2Fit is available in 7 different finishes.

In terms of ease of adjustment, these convertible car seats come with their brand’s respective harness systems. Safety 1st calls their system as QuickFit Harness while Graco markets theirs as Simply Safe Adjust Harness System. Despite the difference in branding, both systems allow users to adjust the seat’s headrest and harness simultaneously.

When it comes to comfort, the Graco Extend2Fit has an advantage over the Safety 1st Grow and Go. Graco’s 3-in-1 car seat comes with 6 recline positions compared to Safety 1st’s 3. The Extend2Fit also features a 4-position adjustable extension panel that offers up to 5-inches of additional legroom. This is especially beneficial if your child has to ride rear-facing for longer.

Child Specifications

Graco’s Extend2Fit has higher weight and height limits compared to Safety 1’s Grow and Go.

Here are the different modes of both car seats.

The Safety 1st and Graco 3-in-1 car seats are designed to “convert” to three modes depending on your child’s age and size. Like infant-only seats, the Safety 1st Grow and Go and Graco Extend2Fit have a rear-facing harness. This position is typically used for newborns and smaller infants. Once your child outgrows this position, you can switch the seats to a forward-facing position. Lastly, you also get a high back booster for kids who exceed the child specifications of the forward-facing mode but are not yet fit for an adult seatbelt.

In their rear-facing mode, Graco can support children weighing up to 50 pounds, while the Grow and Go’s maximum allowable weight is only 40 pounds. This is particularly advantageous for Graco since experts recommend children should ride in rear-facing mode for as long as possible. Toddlers and pre-schoolers, on the other hand, are usually suited for the front-facing mode. Here, both car seats support the same 22 to 65-pound range.

Safety 1st’s Grow and Go and Graco’s Extend2Fit can also handle the same 40 to 100-pound range when converted to a booster seat. Graco’s, however, supports an extra 5 inches in height. The Extend2Fit also comes with 10 adjustable positions for the headrest, while the Grow and Go only offers three. Nonetheless, Safety 1st’s convertible car seat includes specific headrest positions for newborns.

Installation and Safety

The Graco convertible car seat is easier to install than Safety 1st’s Grow and Go.

Both the Safety 1st Grow and Go and Graco Extend2Fit are compatible with the LATCH system, albeit with different variations of it. For instance, the Safety 1st car seat makes use of the standard connectors on LATCH-equipped vehicles. This is comprised of a vehicle’s lower anchors and tethers, specially made for children’s car seats. While it’s a reliable mechanism, it does take a while to install, and a careful reading of your car manual might be in place.

Meanwhile, the Graco Extend2Fit makes use of a proprietary InRight LATCH system. While it still uses the anchors and tethers on your car, Graco includes a one-second LATCH attachment for them. This makes for a faster yet equally secure installation of the car seat. Plus, you will get a visual level indicator that makes it easier to adjust the seat’s recline position. If your car isn’t compatible with LATCH, you can still secure both the Safety 1st and Graco convertible car seats using your vehicle’s seat belts.

In terms of safety, both the Grown and Go and the Extend2Fit meet and exceed federal safety standards. These car seats have been tested for side impacts and are also approved for use in airplanes.


The Graco Extend2Fit car seat has higher weight limits than the Safety 1st Grow and Go. If you’re on a budget, however, Safety 1st’s 3-in-1 convertible car seat is a good alternative.

The Safety 1st Grow and Go and Graco Extend2Fit are high-quality and sturdily built convertible car seats that boast impressive safety features. Graco’s 3-in-1 model, however, has higher weight limits allowing it to be used for an extended period, whether in the rear-facing, front-facing, or booster mode. It also comes with several convenient features, including an easy-to-connect LATCH system and a visual indicator that minimizes the guesswork for installing and readying the car seat.

Of course, all these features do translate to a more expensive product. So if you don’t want to break the bank, then the Safety 1st Grow and Go All-In-One car seat is a great alternative. Despite being less expensive than Graco’s car seats, it doesn’t compromise on safety. The Grow and Go meets all federal safety standards and is actually easier to buckle and unbuckle compared to Extend2Fit. Like the Graco car seat, Safety 1st’s All-In-One has been tested for side impacts and is approved for airplane use.


๐Ÿ“Œ Is Safety 1st a good brand for car seats?

While it doesn’t come with all the bells and whistles of its feature-packed rivals, Safety 1st is a good, less expensive alternative when it comes to car seats. It meets all federal safety standards, too, and comes in several design options.

๐Ÿ“Œ When was the LATCH system on cars introduced?

The LATCH system, which is specially designed for attaching car seats, was required for most vehicles manufactured after September 1, 2002.

๐Ÿ“Œ Is the Graco Extend2Fit seat pad machine washable?

Yes, the seat pad on the Graco Extend2Fit is machine washable.

๐Ÿ“Œ What’s the advantage of an infant-only car seat from a convertible car seat?

Since they’re smaller and much more lightweight, infant-only car seats can double as carriers. Convertible car seats are typically bulkier and heavier and are used only for travel.
