I’ve tested my fair share of convertible car seats, but some of them just didn’t work with my child. When I got my hands on the Cosco Easy Elite 3-in-1 Convertible Car Seat, I was instantly impressed. 

In terms of weight, it’s not much different from other convertible car seats. It accommodates children from 5-80 pounds and works from infancy until your child is ready for a belt-positioning booster. 

I installed the car seat quickly and securely. It was one of the easiest installations I have ever done and it was solid against the seat with no movement. The only problem with this is that you need to rethread the harness straps as your child grows, so you need to remove the car seat each time, which is easier said than done. The same goes for the crotch strap. 

As far as other features go, they’re really no different from other car seats. The only feature we thought stood out was the removable cup holder. You can choose to use it or not to use it and if you remove it, it creates more space for another car seat if you have multiple children. 

I recommend this car seat if you’re on a budget and can’t get your hands on anything else. It doesn’t really stand out from the rest, but it’s a quick fix that’ll keep your child safe and comfortable.

Cosco Easy Elite 3-in-1


Installation depends on your child’s size and height, as well as doctor recommendations. To prepare the car seat make sure it is properly secured in the right position and fully loosen the harness straps and buckle.

Place your child in the car seat with the back and bottom flat against the back. For rear-facing car seats, start with the buckle in the first position and move outward as your child grows.

The harness should rest just below the shoulder. The same is true of forward-facing positioning. To change the position of the buckle, unlatch the harness and turn the car seat over for adjustments. The harness and headrest height can be adjusted with the seat in place.

When rear-facing, the bottom must be parallel with the ground. To change the position, rotate the recline stand out, and move in the direction needed.

Safety Rating and Warranty

Safety is obviously the most important when it comes to young children. The safety ratings for the Cosco Easy Elite exceed all safety standards.

The manufacturer recommends children remain rear-facing for the entire first year and this adjustable, reclining seat makes that possible while keeping your little one comfortable.

Since the American Academy of Pediatrics recommends rear-facing until age two, the extended weight limit of up to 40 pounds in the rear-facing situation is ideal.

For smaller children, the weight range overlap for the rear and forward-facing options is perfect. Height may also come into play, but the Cosco easy Elite 3-in-1 covers this as well. With a height range of 19 to 52 inches, moving up according to how the car seat or booster is used, this car seat will keep your little one safe and secure in the case of an accident.

Given that the Cosco Easy Elite 3-in-1 safety rating exceeds all standards, this is a car seat that can be used for years. In fact, it has a ten-year expiration date from the time of manufacturing. With proper installation of the car seat or booster, this will keep your child safe and secure as you go about your daily life.

If a problem does arise, the product is warranted against defects upon purchase and up to a year from the original purchase if a receipt is available. The product may be repaired or replaced depending on the issue. The warranty does not cover damages from using the car seat incorrectly.


Though some versions of car seats by Costco have had limited recalls, the Easy Elite 3-in-1 has no current recalls on record that can be found. If the car seat and boost version are correctly installed and the child falls within the correct height and weight range, this car seat is a totally safe option.
