Best Car Seats for Every Age
Car seats are the one baby product where you absolutely cannot cut corners. It's also the most confusing category out there — infant seats, convertible seats, all-in-one seats, booster seats, and a maze of weight limits and installation methods. We've simplified it. Here's the short version: you need an infant carrier seat for the first year (the kind with the handle that clicks in and out of a base), then either a convertible seat that goes from rear-facing through forward-facing, or an all-in-one that takes your kid from birth to booster age. The all-in-ones save money long-term but they're big and heavy. We've tested the installation on all of these because a car seat that's hard to install is a car seat that won't be installed correctly. And that matters more than anything.

Frequently Asked Questions
What's the best infant car seat?
The Chicco KeyFit 35. The installation is the easiest we've tested — it practically clicks into place. It's also one of the lightest infant seats out there, which matters a lot when you're lugging it around. The 35-pound weight limit means most babies can use it well past their first birthday. It's been a top pick for years and there's good reason for that.
Should I get a convertible or all-in-one car seat?
If you want one seat that does everything, the Graco 4Ever DLX or Britax One4Life take your kid from 4 pounds all the way to a 120-pound booster. That's potentially 10 years in one seat. The downside is they're big and they stay in the car — you can't carry a sleeping baby in one like you can with an infant carrier. Most families get an infant seat first, then switch to a convertible around age 1.
When can my child switch to a booster seat?
Not until they've outgrown their forward-facing harness seat, which for most kids is around age 5-7 and at least 40 pounds. Don't rush this. The harness distributes crash forces way better than a seatbelt on a small body. The Graco TurboBooster 2.0 is a solid highback booster for when they're ready.
How do I know if the car seat is installed correctly?
The seat shouldn't move more than 1 inch side to side at the belt path. And the angle matters — rear-facing seats need to be reclined enough that your baby's head doesn't flop forward. Most fire stations offer free car seat inspections. Seriously, use that service. Studies show something like 60% of car seats are installed wrong, and even smart parents mess it up. No shame in getting it checked.
