I admittedly find myself undecided in choosing between the Safety 1st Grow and Go and the Graco Extend2fit. It appears that the Extend2fit has “better” features, but let’s look closely to see Grow and Go’s attributes comparative to that of Extend2Fit.

Ideal Use


Safety 1st Grow And Go Graco Extend2fit
Rear-Facing Weight: 5 to 40 pounds 4 to 50 pounds
Rear-Facing Height Limit: 19 to 40 inches Up to 45 inches
Forward-Facing Weight: 22 to 65 pounds
Forward-Facing Height Limit: 29 to 49 inches Up to 49 inches
High Back Booster Weight: 40 to 100 pounds N/A
High Back Booster Height Limit: 43-52 inches N/A


  • They share the same forward-facing weight range and maximum forward facing height limit.



  • Rear Facing.

Minimum Weight/Newborn Fit. If you research further about these two car seat’s fit to newborn, you would likely read that both of them can offer a good fit for babies around 7 pounds in weight, which is the average weight of a newborn. Either car seat would have a too loose harness system for 4-pound infants and preemies, but can provide a secure and a great fit for average-sized newborns.

Maximum weight. Extend2Fit is a good choice for extended rear-facing position (50 pounds vs 40 pounds). This Graco convertible child restraint offers a leg extension panel (a tray that can be extended in 3 positions) that can provide leg room for the growing legs of the child. While this feature does not add to the seat’s safety features, it can help make the child feel less awkward and more content sitting in the child’s restraint.

  • High Back Booster. Safety 1st Grow and Go is the car seat to choose if you want more value for your money since we can further use it as high back booster car seat.


Good All In One Car Seats


Will It Fit In My Car?


Safety 1st Grow And Go Graco Extend2fit
Width 19 inches 19.2 inches
Height 24 inches 22.1 inches
Depth/Length 23.75 inches 25.2 inches


  • Both are great seats if installed as the only car seat inside the vehicle. Either seat is too wide for 3-across installations.



  • Car Models.

According to reviews, they have installed the Extend2Fit with no problems inside Hyundai Veloster, Jeep Cherokee, Chevy Traverse, Toyota Rav 4 and Honda Accord Coupe.

Meanwhile, reviewers of Safety 1st Go and Grow installed the car seat nicely inside Chevy Silverado, Nissan Sentra, and Toyota Rav 4 2017. According to one mom who shared their experience on Amazon, they have used this child restraint in many types of vehicles that include Ford F-150 Crew Cab, Ram 1500 Crew Cab, Tucson, Hyundai, Honda CRV, and Toyota Corolla. She said that it was in the Ford F-150 that the car seat rocked sideways so they had to install it using the vehicle seatbelt instead.

  • Seat Location. Consider the location where you want to place either of these child restraints.  Grow and Go can provide more versatility, since it could be installed in the middle or in any of the outer seat locations of the back seat row. Meanwhile, Extend2Fit could ideally be placed in the middle seat if you wish to take full advantage of the leg extension tray. Fully extended and installed at the back of the driver and front passenger seats, the leg panel could compromise the leg space of the driver and the front passenger so it will be best to install in the middle, if the vehicle permits.

1 forward-facing

6-position recline

1 to 4 for rear-facing;

Lower Anchor Weight Limit: 40 pounds 45 pounds



  • Recline Adjuster. Both of them have a mechanism for recline adjustment that is located at the front.

To adjust the recline angle of Extend2Fit, you must pull the handle at the front and choose the appropriate recline position.

To recline the Grow and Go, you also need to pull out the recline handle and also push backward the top part of the car seat. To make Grow and Go upright, you must pull the recline handle and pull forward the top of the car seat, too.



  • LATCH Connector. The LATCH connector of Extend2Fit is the push-on type, while that of Grow and Go is the j-hook style.
  • Recline Positions. Extend2Fit has more recline positions than Grow and Go (6 vs 3). For rear-facing, positions 1 to 4 can be used while in the forward-facing, position 4 is good for a child below 40 pounds in weight and positions 5 to 6 are ideal for a child above 40 pounds in weight.

Grow and Go has 2 available recline positions (2 to 3) for rear-facing and position 1 for forward-facing, which are said to help the car seat fit into most types of vehicles regardless if the vehicle seat is sloped or not. With this Safety 1st car seat, remember that the higher the number of recline positions, the more reclined the seat will be.

  • Recline/Level Indicator. Extend2Fit has a much easier to use recline indicator, the ball/bubble type. You only need to see if the ball is within the appropriate color to determine if you are using the right recline or level position. Whereas the Grow and Go has lines that you need to visually ensure are parallel to the ground.
  • High Back Booster. It is worth mentioning that Grow and Go is a transitional booster child restraint. In fact, it has been recognized as a Good Bet by 2015 IIHS Booster Ratings. This means that the Grow and Go has a good vehicle seat belt fit in most cars, considering all other conditions like height and weight are within the Grow and Go limits.

With its 18.5-inch shoulder belt guide position, it may not last very long as a booster seat, although this convertible car seat can be a great option in introducing children their new riding responsibilities. In the booster mode, tether and lower anchor connections are not allowed.

  • Real Life Accidents/Safety Testimonials. Both car seats have been highly appreciated and highly rated by parents whose children were safeguarded from harm during unfortunate incidents on the road.

Extend2Fit. One mother said that she bought the car seat at a discounted price during a store sale, but the safety of her daughter was not discounted at all during an accident where their car was totally damaged after spinning on the road and hitting a sign.

Two boys aged 3 and 1 during the accident remained safe and unharmed even though their car rolled over 6 times at a speed of 70 mph.

Grow and Go. A mother recalled how her daughter slept through a significant fender bender, all because she was tucked safely in her Grow and Go car seat.

A toddler did not endure any injury after his mother’s car met a 45 mph car crash. Another car accident happened to a family where all the adult passengers were beaten and bruised, but the baby daughter sitting on the Grow and Go did not get any minor injury at all. It proved the car seat safe and effective that the mother’s sister, who was pregnant and also one of the bruised passengers, quickly got the same seat for her yet to be born child.

  • Both car seats can offer adequate space for the growing passenger. Both have covers that can be removed and washed.
  • They both include infant body support and shoulder pads.
  • They each have 2 cup holders. Yet, Extend2Fit’s cup holders are squarish that it might not fit bottles and cups with bigger diameters.
  • They also share the same lifespan of 10 years.
  • Both of them have buckle holders. Extend2Fit has a Fuss-Free harness storage that will hold the buckle when not in use.  The buckle holder of Grow and Go, while not specifically named, can also hold buckle tongues and harness webbing.



  • Breathability. Both car seats have mixed reviews about breathability of covers.

With Extend2Fit, it has been explained in one of the Q&As on Amazon that the fabric of the cover’s parts close to the child’s body are more breathable than the others.

A mother who bought Grow and Go for her son claimed that her son slept peacefully, cried a little and stayed cool while occupying this car seat. Their family lives in Florida, but they have encountered no issue on the seat being hot.

  • Removable Cover. Both have removable covers, but they differ in terms of the ease in removing the cover. Grow and Go surpass Extend2Fit. To remove the cover of Graco Extend2Fit, you can watch this video and see how taxing and time consuming it is to remove many elastic bands that hold the cover onto the frame.



For the cover of Grow and Go, no need to remove the harness or even uninstall the child restraint.

  • Crotch Position. With this factor, Grow and Go will be a more fitting choice (3 vs 2).  For rear-facing, slots 1 and 2 can be used so choose one nearest to the child with the buckle not under or behind the baby. We can use any slot in the forward-facing.
  • Harness Position. Extend2Fit offers more harness/headrest positions than Grow and Go (10 vs 5). We can use a separate harness position in Grow and Go for newborns, but they do not include it in the no-rethread harness.

For convenience, it will be better to opt for Extend2Fit, but if you want something that has the lowest harness position, then go for the Grow and Go.

The acknowledged headrest/harness positions of Extend2Fit are 10. The lowest is 7 inches with the infant insert, and the highest is 17.5 inches.

For Grow and Go, the declared positions are just 5, the lowest is 10 inches, and the highest is 16.5 inches. However, it provides a separate headrest/harness position (despite not included in the no-rethread harness) that is specifically for newborns. If the infant insert is in place, we can thread the harness into the 6-inches slot. This newborn harness position is a must for babies 6 to 9 months old. There is also a booster guide position at 18.5 inches.

  • Infant Body Support. While both have infant body support inserts, that of Grow and Go can be threaded with the harness straps so it will remain in place.
