Cosco MightyFit 65 Basics

In short, the MightyFit 65 offers parents an inexpensive, lightweight, and compact convertible car seat option.  Proudly made in the USA, the MightyFit 65 is made by American families, for American families.

Safety

First and foremost, the Cosco MightyFit 65 is a two-way car seat meaning you can use it in both a rear-facing and in a forward-facing with harness position.

The MightyFit 65 will support kids from five to 65 pounds.   It is also crash-tested regularly, ensuring compliance with all federal safety standards.

These seats have side impact protection built right into them and are easy to install with or without the LATCH system.  Always refer to your MightyFit 65 car seat manual for detailed installation instructions. MightyFit 65 is also FAA approved for air travel and fits well in most airplane seats.

Features

The Cosco MightyFit 65 also includes many user-friendly features that make parents happy such as multiple heights and buckle positions that adjust easily from the front of the seat.

There are two different recline options in a rear-facing position to help find a good fit for all kids. MightyFit 65 may sound mighty, but it’s a whole lot lighter than other convertible car seats on the market. It weighs in at only 12 pounds!

Additionally, the fabric cover can be painlessly removed and tossed into the washing machine when you inevitably need too. The MightyFit 65 is also pretty compact, giving front seat passengers more legroom when installing in the rear-facing position.

Challenges

Cosco MightyFit 65Unfortunately, as with most convertible car seats, the MightyFit 65 does come with its own set of challenges.  Customer reviews complain that it’s challenging to find the right incline for babies in the rear-facing position.

In fact, many parents have stated that the MightyFit 65 shouldn’t be marketed or used in a rear-facing position at all. It’s just not possible to secure.

Other users mention that the five-point harness straps get tangled way to quickly. Furthermore, the headrest isn’t comfortable, especially for kiddos who like to sleep in the car.

The MightyFit 65 also doesn’t have a booster option.  Once your kids reach 65 pounds, you will need to find them another seat until they’re big enough to use just a lap belt alone.

Parents have criticized that the fabric and padding used in the MightyFit 65 are “cheap” and not cushy or comfy for our little travelers.

Plus, it isn’t compatible with any travel system or stroller, which can be a deal-breaker for infants.  Having to wake a sleeping baby to take them out of the car isn’t anyone’s favorite past-time.

Dimensions

  • 14 inches deep
  • 5 inches wide

  • Forward-facing weight limits: 22-65 pounds.
  • Forward-facing height limit: 28-49 inches.

Expiration

Car seat expiration dates are based upon the date of manufacture.  The Cosco MightyFit 65 will expire roughly six years from the manufacture date printed on the label attached to the seat itself.  You can find the expiration date for your MightyFit 65 stamped into the plastic on the backside of the seat.

MightyFit 65 vs. MightyFit 65 DX

Cosco released an updated version of the MightyFit 65, named the MightyFit 65 DX (or deluxe).  The DX convertible car seat is exactly the same as its little sister.

The updated version is called deluxe for a reason. It currently offers new color choices, luxurious fabrics, and upgraded padding for comfort.

Unique Features in the MightyFit DX

  • Deluxe fabrics.
  • New color choices.
  • Upgraded padding.

MightyFit 65 vs. Safety 1st Guide 65

Safety 1st has its own branded version of the MightyFit 65 DX called the Guide 65.  Don’t be confused; both Cosco and Safety 1st belong to the same parent company, Dorel Juvenile.  So essentially, these two seats are exactly the same, only under a different name.

Unique Features in the Safety 1st Guide 65

  • None! These seats are identical; they only have different names.

MightyFit 65 vs. Cosco Easy Elite

The Cosco Easy Elite 3-in-1 car seat takes the MightyFit 65 to the next level.  Not only can you use this car seat in a rear-facing and front-facing with harness position, but it will also transition into a belt-positioning booster for kids up to 80 pounds.

The Easy Elite is another lightweight, compact car seat from Cosco, weighing only 14 pounds and measuring 18 inches across. Traveling through airport security is going to be a whole lot easier with the Easy Elite, and parents are still able to install three seats across in most vehicles.

Easy Elite also offers some unique features that the MightyFit 65 doesn’t.  Parents can adjust the headrest and harness together in one fell swoop without rethreading.

Easy Elite even comes with an infant insert to help smaller babies fit better.  The updated rear-facing recline can help the Easy Elite fit better in your car too.

Unique Features in the Cosco Easy Elite

  • Convert this seat into a belt-positioning booster.
  • Infant insert included in this model.
  • Adjust the harness and headrest together without rethreading.
  • Updated recline helps the seat fit better in cars.
