Comparison Chart Key
Many different manufactures produce seats which meet today’s safety standards. The chart is sorted alphabetically by brand, but you can sort as needed by clicking the columns.
All model names shown are the most current as of 2018. Britax uses “G4” or “G4.1” to note that these are “generation 4” seats which have been updated from generation 3 (G3).
This is the Rear Facing minimum weight in pounds. Your infant must be at least this weight to fit properly in the seat.
The Rear Facing maximum weight rating in pounds. Since the rear-facing position is the safest, it’s recommended that children ride in this position until at least 2 years of age. Choose a seat with a high rear facing maximum weight rating to allow them to remain in that position longer.
The maximum weight the seat can be used Forward Facing, in inches. Once your child outgrows this weight rating, it will be necessary to move on to a booster seat.
The maximum height of a child who fits in the seat. For taller children, or to remain in a convertible seat longer before moving on to a booster, choose a seat with a higher height limit.
The front to back length of the seat in inches. Keep in mind this rating measures the seat in its most upright position. When reclined, the seat will take up more space in the car, especially in seats with a tall height measurement.
How wide the car seat is in inches. Narrower seats will occupy less seat space. This is helpful in compact cars to allow other passengers to sit comfortably in the back seat. If you’ll be installing two or three car seats along your back seat, choosing a narrow seat will ensure a proper fit even in smaller cars.
How tall the seat is, in inches. Some seats may extend beyond this measurement when adjusted for taller children.
The number of years after manufacture that a seat can be used. All car seats are rated with an expiration date since the protective materials wear out over time. Choosing a seat with a longer expiration date is helpful when using the seat from newborn until the seat is outgrown, or for using the seat for a second toddler when the first outgrows it.
Rated on a dollar-sign scale of 1 to 5. The cheapest seats ($) are below $70. The most expensive ($$$$$) are $300 and above.
