Ideal Use


Graco Extend2fit Graco Size4Me 65
Rear-Facing Weight: 4 to 50 pounds 4 to 40 pounds
Rear-Facing Height Limit: Up to 45 inches No given height limit besides the 1” rule
Forward-Facing Weight: 22 to 65 pounds 20 to 65 lbs
Forward-Facing Height Limit: Up to 49 inches

Both seats have the minimum 4 pounds rear-facing weight requirement, but you might not want to use any of them for newborn infants and preemies meeting this weight limit because their harness could not snugly hold the tiny bodies of the infants.



The Extend2Fit will obviously be the better choice in terms of extended rear facing capacity. Not only will it provide room for the body of a child, but will also have available space for the child’s legs through its leg extension panel.

Nowadays, many car seat manufacturers are designing and making products that can be used longer in the rear-facing mode. Extend2Fit is one of the resonant names you will encounter. That’s because of affordability versus Clek Fllo, Clek Foonf, Diono Rainier*, Nuna Rava*, etc. Its shell is 30 inches tall with fully extended headrest so most children will surely use this up to its 50 pounds limit until they are 4 to 5 years old.

Its name is derived from the retractable extension panel located at the front of the base. This is a tray that can be extended in basically 3 positions (manual says 4 positions, but position 1 is fully retracted). It can give up to 5 inches of space where the child, seated rear facing, can put their legs.  Positions 2 to 4, as per manual instructions, are for children weighing more than 40 pounds. Take note that if you will install this rear facing in a small vehicle, a tall front passenger might feel a bit cramped up because their leg space might be compromised.


Size4Me 65:

There is no height limit indicated in the manual other than the 1-inch rule. This rule means that the child’s head should not reach more than one inch past the top of the headrest.

Remember that you must take this height limit into consideration when the child is seated in the child restraints, not when standing (overall height). It will still depend on your genes, but most kids would likely outgrow this seat by height before they reach the weight limit of 65 pounds.


Good All In One Car Seats


Will It Fit In My Car?


Graco Extend2fit Graco Size4Me 65
Width 19.2 inches 18.5 inches
Height 22.1 inches 23.43 inches
Depth/Length 25.2 inches 22.05 inches



Graco Extend2fit is not the bulkiest seat in the market, but it will be a challenge to  fit 3 of this in a row. In some vehicles, this child restraint may even block the rear window visibility if its headrest is extended at full height.

If your car specifications permit (lower anchors placement), the ideal location for this restraint is the middle back seat.


Size4Me 65:

The Graco Size4Me is also not the most compact of all available child restraints, so it might not fit well in smaller vehicles. However, one parent said that it fits well in his 2010 Chevy Camaro (a two-door sports car) despite his initial skepticism.

Another reviewer said that it fits well both rear facing and forward facing with enough room for other passengers in his Hyundai Elantra.


Good 2-Way Car Seats

Do I need to use a pool noodle/rolled towel? No Yes
Easy To Install Rear-Facing?

Yes, by LATCH

No, by the seatbelt

Yes, especially by LATCH
Easy To Install Forward-Facing?

No, by LATCH

Yes, by the seatbelt

Yes, especially by LATCH

Recline Position

6-position recline:

1 to 4 for rear facing;

4 to 6 for forward facing

3-position recline:

1 for rear facing;

Lower Anchor Weight Limit: 45 pounds

In terms of using a pool noodle or rolled towels, you will find that you would not need these aftermarket products to install the Extend2Fit in the appropriate recline angle because it offers a greater number of available recline positions than the Size4Me 65.

Both seats might offer at least a similar level of ease/difficulty in installation.

Both have ball/bubble level indicators and they also have 45 pounds lower anchors weight limits.

Both car seats have mixed reviews. While most are pleased about their purchases, others still find themselves disappointed.  Some claim that they cannot get the LATCH and vehicle seatbelt securely installed, which is probably due to the different models of cars and types of seats that their cars have.

Graco Extend2fit Graco Size4Me 65
Country Of Origin: China
Steel Frame: Yes No
Five-Point Harness? Yes
Side Impact Tested: Yes
Approved For Airplane Use: Yes
Easy To Buckle And Unbuckle? No

Both seats have been subjected to rigorous testing to ensure their safety, but Extend2Fit is a better choice because it is sturdier with its steel frame.



Apart from the tests and quality control procedures that this product have gone through, Extend2Fit has also been proven to effectively keep babies safe in real life accidents and crash scenarios.

In one incident, children aged 3 and 1 in forward facing and in rear-facing car seats were unharmed despite their car rolling over 6 times at a speed of 70 mph.

In another review, one mother noted that she would get another of this product because the first Extend2Fit that they received as a gift had to be replaced after their car was rear-ended. Throughout the incident, the baby remained asleep and safe in her car seat.

There is one weird, but noteworthy detail about this car seat’s safety. At least one parent noticed that the warning label of Extend2fit is screen-printed on the cover and if the temperature gets high, this might burn the child’s skin.

There are some parents who report issues such as difficulty in getting the seat in the reclination they prefer so as to prevent their children from slumping their heads when they fall asleep during the ride.

Others complain about not getting a tight fit with the harness straps. The harness straps of Extend2Fit were found by a number of parents to be difficult to tighten and to loosen. The straps are also reported to easily twist when the child is buckled into the seat.


Size4Me 65:

According to Graco, this product exceeds all applicable Federal Standards although it has no steel frame. Still, it would be a good choice for budget-concerned parents.

Reviewers noted that this product could improve on its harness straps (make them easier to tighten/loosen) and buckle features.

Both Extend2Fit and Size4Me 65 have machine-washable fabric/covers that are not very comfortable for children.

Some parents prefer heavier seats, they equate it with being safer. Some parents prefer “lighter” ones to easily carry them for air travel. Whatever your main use of these seats is, their weights are not that different.



The Extend2fit is adequately padded, although not as thickly padded as other brands of car seats.

The fabric weave of its cover is described to be too loose that it can easily capture dirt and thus require frequent washing.

The cover is attached to the frame with somewhat small band of elastics that are difficult to work with. Just removing the cover would take a lot of time. You may get the Extend2Fit RapidRemove Cover version* instead to save on time.

With the time necessary to completely air dry the cover, you would probably be able to replace the cover and use the seat again the next day.

Extend2Fit has 2 cup holders, which you might like more than the single cup holder in Size4Me. However, the cup holders of Extend2Fit are square in shape so they can only hold cups with smaller diameters.



Size4Me 65:

The Graco Size4Me has a RapidRemove cover version* , too, that can be easily and quickly removed in about 60 seconds.

Just like Extend2Fit, the Size4Me 65 also has a no-rethread harness. You just lift its red button at the top and move up/down to make necessary adjustments.

Size4Me may have only one cup holder, but it is circular in shape so it can hold far better than the square cup holders of Extend2Fit.

It seems that Graco needs to pay attention to the design of its car seats’ harness straps. Just like the Extend2Fit, the Graco Size4Me product has also been reported to have straps that are too difficult to tighten. This is not a rare incident because one parent said that they have 3 of this seat and all of them have shoulder straps that do not seem to tighten no matter what they do.

The expiration of the Graco Size4Me is 7 years but some reviewers noted that they have already seen signs of wear, fraying and ripping after several months of use. At first, one parent expressed disappointment about Graco customer service, but later on updated with a more positive comment. Apparently, Graco offered them a replacement for their worn seat despite the few months beyond their warranty. This replacement was far better than what they originally had.
