By now you probably realize you’re going to need a car seat before you can take your baby anywhere, to the store, from the store, even home from the hospital. How do you choose the right car seat for your infant with so many models around? The stress can be overwhelming. There also seem to be so many different types of car seats out there.

First, some good news – every new car seat on the market is obligated to meet government safety regulations, so buying a cheaper car seat doesn’t necessarily mean it will be less safe. In this guide, we’ll review the five best Britax car seats for infants.

The price involves the extra features you’ll get, like a bigger canopy, additional safety features that are not currently required by the government, and easier installation among other things.

Infant Car Seat Types

First, you should know that there are three types of car seats on the market, broadly speaking. What is the difference between them? Basically, they are appropriate for different stages of your child’s life as it grows and offer different advantages. Car seat laws may well vary by state, but infants nationwide have to be in rear-facing seats, while toddlers can be in either front or rear-facing seats as long as they meet the weight and height requirements. Older children have to ride in a booster seat in most states. Here’s a quick clarification:

Car Seats for Infants

These seats are appropriate for newborns through to the time your child reaches the seat’s height or weight limit (usually 30 pounds on average). These seats are always rear-facing. When the child outgrows the infant car seat, you’ll have to buy a front-facing seat, like a convertible that is designed to accommodate toddlers.


These seats switch to forward-facing seats for older children from rear-facing seats for babies and toddlers. The forward-facing position usually holds children up to 65 pounds.


Booster car seats are to be used between the time your child needs a car seat to when they can begin using the regular seat belt for adults. A booster seat will help your child sit up higher so your car’s regular shoulder and lap belt crosses his or her body at the right points and holds them safely. These seats are designed for kids who are at least four and weight at least 40 pounds.

Our Number 1 Pick: Britax B-Safe 35 Infant Car Seat

The B-Safe is our top pick because of its stellar safety features and great price. This car seat offers the absolute best price to quality ratio. The deep, narrow seat ensures excellent side-impact protection thanks to its sidewalls using energy-absorbing foam. If your car is small, this is the perfect choice because the seat won’t take up too much space in the back.

It is also very easy to install thanks to the highly effective SafeCenter Latch System. Keep in mind, though, that installation isn’t so simple if you don’t have the base. This means perhaps this model won’t be ideal for you if you’ll need to use this seat in cabs and friends’ cars on occasion.

According to real users, the car seat feels very sturdy and has excellent safety ratings. Infants feel comfortable in it. The steel frame, impact-absorbing base, and easy installation offer an uncontested level of protection, enabling parents to travel in total confidence. On the downside, the steel frame makes the seat heavier than most of the others in its class, including the ones we’ve reviewed in this article.

  • Layer of side impact protection
  • Steel frame
  • Impact absorbing base
  • Easy to install with Safe Center LATCH
  • The seat is secured via built-in seatbelt lock-offs
  • The seat is compatible with Britax B-Agile Strollers
  • Optimal installation angle via spring-assisted recline and indicators
  • Seat is narrow
  • Steel frame is heavy

Our Second Choice: Britax Marathon

The Britax Marathon is a bestseller that functions as a front-facing seat for children who are 20–60 pounds and rear-facing car seat with babies 5–40 pounds. This is one of the best car seats out there for infants and young children thanks to Safe Cell Impact Protection, a unique cushioning system.

This is a very user-friendly seat with outstanding safety features. The base is easy to install. It is held safely in place with a tightener in the middle. The built-in, easy-to-read level shows you if the seat has been positioned correctly.

The key to safety being proper installation, we find this is the best carrier for comfort, safety, and convenience. The seat features a removable newborn insert, a thickly cushioned seat lined with energy-absorbing foam for increased comfort and safety, and an easy to use latch adjustment that ensures quick and correct installment from either side of the car, giving you assurance that your child is safely secured.

  • Padded, deep side wings
  • Multi-position recline
  • Superior protection – foot prop provides extra stability
  • Practical – quick-remove cover
  • No need to remove harness
  • Perfect fit – height-adjustable headrest
  • Harness with easy single-handed adjustment
  • Indicators confirm the ISOFIX hooks are engaged
  • Costs over $200
  • Not Equipped with Booster Seat

Our Third Choice: Britax Boulevard ClickTight Convertible Car Seat

The Boulevard ClickTight convertible car seat features a Click & Safe Snug Harness Indicator, a patented ClickTight Installation System, and an extra layer of side impact protection. You can rest assured your child will be safe with the SafeCell Impact Protection. The seat is very easy to install – just buckle the seatbelt and the ClickTight Installation System will do the rest for you.

The Boulevard Car Seat is equipped with the patented Britax SafeCell Impact Protection system which includes an energy-absorbing base, steel frame, staged-release stitches that slow and reduce forward movement in the event of a collision, and V-shaped tether to minimize seat rotation. Britax designed the Boulevard ClickTight Car Seat with a deep foam-lined shell and head protection to protect your child from side impacts, 2 strong layers of side energy absorption, plush foam padding and fabric and 7 recline positions to guarantee your child premium comfort.

You can change the height of the seat simply by pushing a button – no rethreading necessary. This is possible because the 14-position easy-adjust harness grows along with your child. The right tightness is ensured this way and you don’t need to worry about that. The harness indicator makes a click when it’s properly adjusted.

The Boulevard car seat can be used forward-facing 20-65 pounds and rear-facing 5-40 pounds, child standing height up to 49 inches.

  • Easy to install with patented ClickTight technology
  • No need to rethread thanks to the quick-adjust 14-position harness
  • Indicator makes sound when the harness is tight
  • Safety guaranteed: 2 layers of side impact protection
  • Steel frame and impact absorbing base
  • Engineered to exceed US standard FMVSS 213
  • Rigorously crash tested to meet or exceed all U.S. safety standards
  • Some users say straps are hard to adjust

Our Number 4 Pick: Advocate Click Tight

This top-rated convertible infant car seat has a groundbreaking installation that makes sure the seat is safely and correctly installed. It features several layers of side impact protection, an impact-absorbing base, a snug harness indicator, and a steel frame.

Combined, these make sure your child is very safe. This seat’s installation system is an example of very safe, very easy technology. All a parent needs to do is open the front of the car seat, buckle the seat belt, and click the seat shut. It will never budge and you won’t have to worry about anything when you’re on the move with your child.

Britax’s unique, patented system of safety components provides unmatched protection. It includes staged-release stitches that slow and reduce forward movement during a collision. As one-fourth of crashes are accounted for by side impacts (these also result in the most severe injuries), Britax has taken measures to prevent such an unfortunate turn of events, designing the Advocate ClickTight with these exact data and considerations in mind.

The seat has quick-adjust head protection, deep foam-lined shell, and side cushions – this comes to three layers of side protection for your child in total and the best possible protection. Being big on statistics, Britax has taken into account that up to two-thirds of car seat harnesses are too loose, which is why they patented the Click & Safe Snug Harness Indicator.

The Advocate ClickTight can hold your kids safely and comfortably from birth until the end of their preschool years. The easy-adjust harness features various positions, guaranteeing the flexibility to grow along with your child or children.

  • LATCH system
  • Three layers of side protection
  • Easy-to-adjust-and-tighten harness
  • Plenty of accessories available
  • 10-year life span
  • Seven-position recline system
  • Forward-facing & rear-facing
  • ClickTight installation system
  • No cupholder
  • Bulky and heavy
  • Not part of a travel system
  • Expensive

Number 5: Britax Pinnacle ClickTight G1.1 Harness-2-Booster Car Seat

The Britax Pinnacle G1.1 has everything a booster car seat needs. It keeps kids safe until they don’t need a booster seat anymore. This is achieved by providing the highest weight and height limits available on the market as far as any booster seat is concerned (apart from the lower-priced Frontier). The Pinnacle features an extensive amount of side impact protection on top of a user-friendly, excellent installation system.

Last year, Britax updated the Pinnacle 90 and renamed it the Pinnacle G.1.1. The weight and height limits are still the same – forward-facing: 25-90 pounds, and between 30 and 58″ in height. The top harness straps need to either be at or above your child’s shoulders, and the ears of the child must not extend above the headrest. Your child should be at least 2-years-old. The seated shoulder height of the child can range between 12.5 and 20.5.”

The Britax Pinnacle ClickTight G1.1 is one of the best combination seats on the market apart from being one of the top booster seats on the market. It continues a tradition of versatile, high weight and height car seats that make it a market leader.

Although it can be used as both a forward-facing seat and a booster, it is recommended that children remain rear-facing for as long as possible for safety reasons. Infants in Sweden, which has the lowest child fatality rate in the world, remain rear-facing up to 4 years. After this period is over, the kid should remain forward-facing as long as possible. Also note that if the child weighs more than 65 pounds, using a harness is required when using the seat in harnessed mode, although the company recommends it in every installation.

  • Steel frame keeps seat from flexing forward during crash
  • Color coded belt paths help in routing vehicle seat belts
  • Energy-absorbing, impact protection
  • EPP foam around the child’s head and body to augment impact protection
  • Modern design with rounded shape bottom allows for a better fit
  • Design is easy on all types of vehicle upholstery
  • Shoulder strap hard to adjust

When Buying a Britax Car Seat for Your Infant

We hope you’ve enjoyed our top 5 infant car seats review so far. Below are some more tips on what to consider when you’re looking to buy an infant car seat.

If you’re planning on buying a used car seat – because it’s cheaper or for whatever other reason – keep in mind that apart from the likelihood of it being damaged, it may not meet effective safety regulations.

If you must buy a used one, buy it from someone you trust. Make sure to look up its expiration date and check if the model has ever been recalled.

Type of Seat

Should you go for a convertible seat or an infant seat? Check out the beginning of this article if you haven’t or if you’ve forgotten what the difference between the two was. It may seem like purchasing a convertible car seat would be the more efficient option, but that isn’t necessarily the case. Using an infant car seat has a series of distinct advantages.

First and foremost among them is that the baby will be less likely to wake up. There will be no need to unbuckle and lift him or her out of the seat if you need to leave the car and rouse them out of a peaceful nap. You just lift the infant car seat from its base and attach it to the stroller to use as a cozy resting spot.

Always make sure your car seat is compatible with your stroller before you buy either. It would be most reasonable to choose the car seat model before the stroller model and then get a model made by the same brand. Or you could go for a travel system – this is where a stroller and car seat come as a set. If there’s a car seat you adore (one of the five here) that differs from your stroller, try to find out if a separate adapter is available to fit them together.

Does the Seat Fit?

OK, this one may seem obvious, but you’d be surprised at how many customers fail to check this before they buy an infant car seat. If you’ll be switching the seat in and out of different cars, you’ll need to check whether it fits in every single one.

We have some tips on the best car seat if this will be the case toward the beginning of this article. Please keep in mind that every car seat is different—some seats fit better in smaller cars, and others in larger ones.

Our Final Review

Please note that the fabrics must be machine washed separately in cold water on delicate cycle. Drip dry and do not use bleach. You can clean plastics and hardware using a sponge, warm water, and mild soap. We recommend towel drying. If you need to clean the harness, do so using a sponge, warm water, and mild soap. Air dry, and never machine wash the harness.

Once you buy an infant car seat, do not remove the tags or throw away the box immediately. You’ll want to test it first and make sure it’s a good fit. If not, you don’t want to be stuck with it, do you? If you buy a new seat, it will be safe in 100% of the cases. The key factor is whether the seat will make travelling around easier.
