Independent research from manufacturer manuals. How I review car seats
Baby car seats, compared by stage and fit
228 US baby car seats from 15 brands, compared by the weight, height and age limits each manufacturer publishes in its own manual. Start with your child’s stage, then check the limits that decide whether a seat actually fits them and your car.
Specifications checked September 17, 2026. No hands-on or crash testing. How I research
How old is your child?
Pick a stage to see which seat types usually suit it. Your child’s size and readiness decide the next step, not a birthday.
Start rear-facing
A newborn can use an infant seat or a rear-facing convertible that meets every fit requirement. Decide whether you want a removable carrier.
- Typical ages
- First weeks and months
- Typical seat limits
- Infant seats: typically up to 22 to 35 lb and 26 to 35 in, rear-facing only.
Ages follow NHTSA’s age groups; seat limits are typical ranges from the American Academy of Pediatrics. Your seat’s manual sets the real limits. Read the complete stages guide.
