Graco Extend2Fit 3-in-1 Car Seat Review

Graco Extend2Fit 3-in-1 Car Seat Review

  • Harness storage is fuss-free
  • Engineered by ProtectPlus
  • Easy-to-adjust harness with no re-threading
  • One-second LATCH attachment
  • One motion harness and headrest height adjustment

Parents usually consider Graco Extend2Fit as an option when deciding on a perfect car seat for their little ones. Let’s scrutinize the major and significant properties of extend2fit. The best thing is that it is a 3-in-1 car seat for infants.

Firstly, the most important concern is installation and a number of people struggle while installing a car seat correctly. Well, the good news is extend2fit 3-in-1 is not going to give a tough time in this regard, the base is built-in so it doesn’t need to be removed.

Yet, people prefer to install it by choosing the incline position before they place it into the car’s seat. This is because the accessibility adjustment lever is hindered once the car seat is placed into the vehicle’s seat as it is hidden between both these seats. 

Considering its weight, Graco extend2fit is not very heavy and can be effortlessly lifted with one hand. Notwithstanding, if your little one is inside the car seat, it can be a bit troublesome for you to carry it with one hand.

Furthermore, it has a 4-position extension panel and offers additional rear-facing legroom as much as 5’’, and the rear-facing side is safer for children. Another perk of extend2fit is that it is an investment that is going to benefit for a longer period of time.

The adjustable extension belt and 50- lb rear-facing weight limit make this possible for you to set the car seat according to the new requirements, as your child grows.

At times harnessing can really get on your nerves because it usually gets in the way while you put the child in and out of the car seat but extend2fit has something unique to offer, it has special pockets which keep the harness out of the way and make it less tiring for you. Plus its fabric gives kids space to breathe during hot days. 

The Simply Safe Adjust Harness System makes it very easy to adjust the height of the headrest and harness. Similarly, LATCH attachment takes only a second, all thanks to InRight. Moving on to the load-bearing capacity, it is capable of bearing up to 100 lb.

Undoubtedly, safety is every parent’s primary concern and Extend2fit gives maximum protection, provided that you keep the child rear-facing for as much time as possible. 

 It is convenient to keep it clean because it’s easy-to-remove covers, so no worries about the bacteria and germs that can otherwise be harmful to your child. Its special features make this product popular amongst potential customers. 

  • Easily fits in small spaces
  • Ensures safety

This investment will give you advantages in the long run as it has numerous configurations so that it can be modified as the child grows and a 4-position recline is the cherry on top. Its steel-reinforced frame makes it durable for 10 years. 

Another thing that makes it highly recommended is the Simply Safe Adjust Harness System that allows you to easily adjust the height of the harness and headrest in a single motion.

Further, it offers you 10 positions and gives you plenty of options to choose from. The cover and pads of this car seat can easily be removed and washed hence, it is easy to clean and the germs can easily be kept away. The InRight latch system is a bonus point for slimfit car seats.

Graco Extend2fit Vs Slimfit: Detailed Comparison

Now that we have a pretty much in-detail and thorough description of both products under discussion let me summarize the differences in some salient features of Graco extend2fit and slimfit and make it even simpler for you. 

High Back Belt-Positioning Booster

This is one of the key differences. If your child doesn’t feel comfortable in the forward-facing mode anymore, then Graco Slimfit has got this impressive feature of converting the car seat into a High Back Belt-Positioning Booster.

On the contrary, Extend2fit has no such feature to offer so isn’t suitable if you wish to use forward-facing for a toddler. 

3-Position Extension Panel

Graco Extend2fit has a 3-position extension panel whereas the Slimfit lacks this feature. The 3-position extension panel allows you to use the rear-facing mode of the car seat for a longer time and the 5-Inch additional legroom supports this.

Additionally, this additional legroom also lets the kid use rear-facing mode till their weight is 50 lbs. Therefore, Extend2fit can be used for a longer period of time without making your child feel uncomfortable. 

Recline Positions

When we talk about recline position I think extend2fit for sure takes the lead. Slimfit offers only 4 recline positions while extend2fit offers 6 recline positions.

More recline positions mean more comfort. From the above information, it is very clear that extend2fit offers more room for customization. 

Space Occupation

Slimfit has a slimmer design. Its dual cup holders, when rotated, save 10 % space of the back seat, therefore, making room to accommodate other car seats. For me, the best part is that though it’s slimmer than usual Graco car seats, including Extend2fit, it does not compromise on comfort. 

Long-Run Use

Slimfit can fit a child weighing 100 pounds whereas Graco Extend2fit is only usable for a child to the weight of 65 pounds. It goes without saying that Slimfit works for longer as evident from the huge gap between the weight-bearing capacity of the two. 

Final Words

Streamlining the above discussion about the uses, pluses, and negatives of Graco Extend2fit and Slimfit we can infer that the best choice depends on the needs and demands of the parents.

In general, both the products offer value for the money and diverse features. If you want to use it for a longer period of time, then Slimfit is suitable for you and if you are taking into account the number of recline positions then extend2fit is reasonable for you.
