​The best Cosco car seat in our estimation is the Comfy convertible car seat. This product is perfect for children who weigh between five and 50 pounds, making it one of the most versatile car seats on our list. When installed facing the rear, babies up to 40 pounds ride safely and comfortably in your car. For heavier kids, the forward-facing installation is optimal. Either way, children benefit from a five-point harness system. Parents appreciate the easy installation and adjustability. We love the side-impact technology and reinforced construction.

Key Features

  • ​Five-point harness system
  • ​Side-impact technology

​The second car seat on our list could easily have been the first. The Cosco MightyFit 65 DX convertible car seat keeps kids safe as they grow. In fact, this seat is perfect for children from five to 65 pounds. Like the Comfy convertible car seat, the MightyFit 65 DX seat offers both forward and rear-facing installation option. Its side-impact technology and five-point harness system compare to the Comfy convertible car seat as well. Some users find this seat to be difficult to clean, though, causing us to rank it second on our list. Nonetheless, for a good, all-around car seat, the MightyFit 65 DX convertible car seat is an excellent choice.

[amazon fields=”B006ZISVSO” value=”thumb” image_size=”large”]

[amazon fields=”B006ZISVSO” value=”button” button_detail_text=”Learn On Amazon”]

​Unlike the first two entries on our list, the Cosco Ambassador backless booster car seat isn’t appropriate for a wide range of children. Instead, this seat works for older children who weigh between 40 and 100 pounds. The seat boosts kids so they can use your vehicle’s seatbelts safely and comfortably. This product has a lightweight design and offers substantial support.

#4: Cosco Lift and Stroll Plus Travel System

[amazon fields=”B01I2BZVBQ” value=”button” button_detail_text=”Learn On Amazon”]

​If you want to combine a car seat and stroller into one useful device, the Cosco Lift and Stroll Plus Travel System is worth a look. The car seat attaches to a functional stroller quickly and easily. When you are ready to take a trip in the car, simply detach the car seat and install it in your vehicle using the four-point harness system. Since it allows you to combine equipment, we like this car seat quite a bit. Still, this car seat is the most expensive one on our list.


​#5. Cosco Finale DX 2-in-1 Booster Car Seat

[amazon fields=”B073VRFM5G” value=”thumb” image_size=”large”][amazon fields=”B073VRFM5G” value=”button” button_detail_text=”Learn On Amazon”]

​The Cosco Finale DX 2-in-1 booster car seat eliminates the need for car seat upgrades as your child ages. Instead, you use the first setup of this seat for children up to 65 pounds and the second one for kids who weigh up to 100 pounds. We like the cleanability of this seat. Some users, though, complain about the thin padding. Nonetheless, the affordable budget, included cup holders and machine-washable fabrics make this a decent car seat.

​#6: Cosco Easy Elite 3-in-1 Convertible Car Seat

[amazon fields=”B07D5NQ294″ value=”thumb” image_size=”large”][amazon fields=”B07D5NQ294″ value=”button” button_detail_text=”Learn On Amazon”]

​Like the DX 2-in-1 seat, the Easy Elite 3-in-1 convertible car seat is useful for your growing children. Its rear-facing installation works for children up to 40 pounds. A forward-facing option protects kids who weigh up to 65 pounds. Then, remove the sides and boost kids who weigh up to 80 pounds. Unfortunately, this car seat is not appropriate for heavier children. It can also be difficult to convert and time-consuming to install. Still, we like the usability and design of the Easy Elite 3-in-1 convertible car seat.

#7: Cosco Apt 50 Convertible Car Seat

[amazon fields=”B00PNXI5PQ” value=”thumb” image_size=”large”][amazon fields=”B00PNXI5PQ” value=”button” button_detail_text=”Learn On Amazon”]

​The Cosco Apt 50 convertible car seat is simple and sleek. It is also effective at protecting children who weigh up to 50 pounds. The seat’s five-point harness system is intuitive. Fashion-conscious parents love this seat, as it comes in a couple vibrant, cool colors. Even better, the included cup holders and washable fabrics make this seat ideal for busy families. Still, while this seat has six harness heights, some users reported discomfort with harness positioning.

[amazon fields=”B01GISW3SY” value=”thumb” image_size=”large”]

[amazon fields=”B01GISW3SY” value=”button” button_detail_text=”Learn On Amazon”]

​Another excellent booster from Cosco is the Rightway. This seat is a belt-positioning booster that accommodates children who weigh between 40 and 100 pounds. Its adjustable headrest supports growing kids. Further, the lightweight design and durable construction make this seat optimal for busy, active families. Some customers expressed disappointment with the stain-resistant fabric, noting that it has a rigid feel. We like this seat for its affordable budget and easy installation.

#9: Cosco Rise Booster Car Seat

[amazon fields=”B0713Q5QLM” value=”thumb” image_size=”large”][amazon fields=”B0713Q5QLM” value=”button” button_detail_text=”Learn On Amazon”]

​Boosters don’t have to be complicated to be effective. The Cosco Rise booster car seat gives your growing children the boost they need to use your vehicle’s standard restraint system. This seat works well for children who weigh between 40 and 100 pounds. It includes armrests to promote a safe ride. Still, the armrests are not padded, meaning this booster can be a tad uncomfortable on long trips. It is incredibly affordable, though, making this seat ideal for budget-conscious shoppers.

#10: Cosco Light ‘N Comfy 22 DX Infant Car Seat​

[amazon fields=”B01ETUBFZ0″ value=”thumb” image_size=”large”][amazon fields=”B01ETUBFZ0″ value=”button” button_detail_text=”Learn On Amazon”]

​The last Cosco car seat on our list is the Light ‘n Comfy 22 DX infant car seat. This one features comfortable fabrics, plush padding and a reclined design. We ranked this seat last on our list due to its limited functionality. That is, this seat is only appropriate for infants. After your baby weighs more than 22 pounds, you must upgrade this car seat. Still, we love its security features and printed patterns.

​The Verdict

Keeping children safe when they are traveling in motor vehicles must be a top priority for parents everywhere. Cosco has a complete line of car seats, with each offering designed to meet different needs. The best in our opinion is the Cosco Comfy convertible car seat. This all-around car seat is appropriate for children as they grow from infants to toddlers. If you are looking for a car seat for larger children, the Rightway is hard to beat.
