Car Seats Guide: Safety & Buying Tips

Choosing the right car seat is one of the most important decisions for your child's safety. Explore our comprehensive guide to infant, convertible, and booster seats.

SHOP RECOMMENDED CAR SEATS

Did you know? According to the CDC, motor vehicle injuries are a leading cause of death among children. Properly using a car seat reduces the risk of death by 71% for infants and 54% for toddlers. Let us help you find the perfect seat for your little one.

Types of Car Seats

Understanding the different types of car seats is the first step to making an informed choice. Each type is designed for specific age, weight, and height ranges.

Infant car seat with base and handle

Infant Car Seats

$150–$400

Rear-facing only seats designed for newborns and small babies. They are portable and can be clicked into a base that stays in the car, or used with a stroller as a travel system.

Best for: Birth to 22–35 lbs, up to 30–32 inches.

Convertible car seat rear and forward facing

Convertible Car Seats

$200–$600

Convertible seats can be used rear-facing and then converted to forward-facing as your child grows. They are bulkier but last much longer.

Best for: 5–65 lbs, depending on model.

Booster seat for older children

Booster Seats

$50–$200

Booster seats position the vehicle's seat belt correctly over the child's body. They come in high-back and backless versions.

Best for: 40–100+ lbs, up to 4 feet 9 inches.

Safety Standards & Ratings

All car seats sold in the US must meet Federal Safety Standard FMVSS 213. However, some seats exceed the minimum requirements with additional safety features.

Buying Guide: How to Choose the Right Car Seat

Step by step car seat installation guide

Choosing the best car seat involves more than just picking the most expensive model. Here are key factors to consider:

1. Your Child's Age, Weight & Height

Always follow the manufacturer's guidelines. Keep your child rear-facing as long as possible – at least until age 2 or until they reach the maximum height/weight limit for rear-facing mode. Many convertible seats now support rear-facing up to 50 lbs.

2. Vehicle Compatibility

Not all car seats fit all vehicles. Check the seat's dimensions and whether your car has LATCH anchors or you'll need to use the seat belt. Some seats are narrower and better for small cars or three-across configurations.

3. Ease of Installation

A seat that is difficult to install is more likely to be installed incorrectly. Look for features like push-on LATCH connectors, base level indicators, and adjustable headrests that make installation simpler.

4. Additional Features

Consider extras like multiple recline positions, no-rethread harness, machine-washable covers, and built-in cup holders. These can make daily use more convenient.

5. Expiration Date

Car seats have an expiration date (usually 6–10 years from manufacture). Never use an expired seat, as materials can degrade and safety standards may change.

Pro Tip: If you're planning to have more children, a convertible seat that lasts from birth to booster-ready stage is a great investment. Alternatively, an infant seat + a convertible seat combo is a popular choice for many families. Explore our travel systems guide for compatible strollers and car seats.

Frequently Asked Questions

When should I switch from infant to convertible car seat?

Switch when your baby exceeds the infant seat's height or weight limit, or when the top of the head is less than 1 inch from the top of the shell.

Can I use a car seat after a minor crash?

Most manufacturers recommend replacing any seat involved in a moderate to severe crash. Check your manual. Some allow use after a minor crash if all criteria are met.

Is it safe to buy a used car seat?

We strongly recommend against buying used car seats unless you personally know the history and are certain it hasn't been in a crash, is not expired, and has all parts. For peace of mind, consider our second-hand guide for other baby items instead.
