Child’s Safety Protection

Britax Boulevard convertible car seats are built with complete safety of your child in mind using proprietary 360 degree Protection system.  The advanced safety features work together to minimize injury to a child during a crash.  As parents, a crash with our child onboard is unthinkable, but investing on the safety features of a Boulevard prepares and reduces the nasty outcomes of a crash by:

  • Ensuring your child is secured in the car during a crash
  • Altogether acts like a cocoon and diverts  crash forces away from your child
  • Slows down and minimizes your child body movement during a crash and so preventing injury to the child, particularly brain and spinal injuries.

Britax Boulevard car seats have all the safety features that are available on the Marathon 70 which we have reviewed, plus some important enhancements.  A True Side Impact Protection is a key difference in safety features of the two models. Britax Boulevard range has a True Side Impact Protection system that incorporates deep and comfortable side walls, a head restraint you can adjust to suit the height of your child, with extra layer of EPP (Expanded Polypropylene) foam that will better absorb crash energy from your child’s head, neck and spine.

The Boulevard 70, 70 CS & 70-G3 are designed to shield and give your child maximum protection from crash forces experienced from the two most common types of  crashes – side and frontal crash impacts.

Child Age and Size

As with all recent Britax convertible car seats, the Boulevard 70 in the rear-facing position will fit children weighting 5 to 40 pounds, and in the forward  facing position, it will fit children from one year old and 20 pounds, up to 70 pounds.

The forward facing 70 pounds high capacity of the car seat ensure your child will continue to use the same car seat from baby through toddler and so removing the need to invest in another car seat as your child grows.

Research has shown that Children are safest in a rear-facing position during a crash. The American Academy of Paediatrics and the National Highway Traffic Safety Administration recommend keeping children in the rear-facing position as long as possible, up to 2 years.

As children grow, the rear-facing position can be uncomfortable for a child due to limited leg room, and you may consider switching the child to forwarding facing position.  The Boulevard 70 360 degree safety features work together to give your child maximum protection in rear or forward facing positions.

Ease of Use

One of the lasting first impressions about any car seat, after the look and feel is how difficult or easy it is to fit the car seat in your car – and here all can easily go wrong if you’ve made the wrong choice of car seat for your child.  Some car seats are notoriously difficult to fit and can leave parents dreading the exercise. But this is not the case with Britax convertible car seats, and Boulevard 70 CS and 70-G3 have gone a step further with a Click & Safe feature that takes the guess work out of fitting a child snugly in a car seat.

Britax Boulevard Convertible Car Seat Click & Safe

The LATCH system available in all Britax convertible car seats allow you to easily achieve a quick and tight installation of the car sit in your car using push button and  premium lower latch connectors.
It also features a Click & Safe device that gives an audible sound to assist parents determine when a child is snugly and safely fitted when adjusting the tangle snug harness.  This is a feature that is not available in the Boulevard 70.

It is a good practice to always double check if your child is secured and comfortably fitted. This is easily done by pinching the harness at the shoulder, and making sure there are NO excess straps or webbing.  This simple check is a reassuring indication that your child is securely and snugly fitted in the car seat.

Child’s Comfort

A child car seat may have the best safety features, but if your child finds it uncomfortable to use, it can be a nightmare for parents to focus when driving and at the same time peep and stretch, in attempts to reach out and comfort a fretting child – not a safe situation but one we know as parents happens too often.

Britax Boulevard range of convertible car seats are engineered to over come this common issue with high density comfort foam, reclining positions whether a child is rear or forwarding facing, plush cover and tangle free five- point harness.

Britax Boulevard Convertible Car Seat Comfort Features

The design and material used in the Boulevard offer so much comfort to a child that many parents mentioned it many consumer reviews. And you can add the belly pad that gives extra snugness to a child. You can’t go wrong with any Britax Boulevard convertible car seat if your choice is based on child’s car safety and comfort.

Easy to Clean

You can easily remove the plush seat cover and matching pads for cleaning, without dismantling or removing the car seat.  It is recommended to spot clean, or hand wash car seats as they are made of fire retardant material, and machine wash may reduce the fire protection offered by the car seat cover.

Always follow the cleaning instruction specified for any car seat.

Size and Fit

Britax Boulevard convertible car seats range, whether the 70, 70 CS or 70-G3, are designed to accommodate children weighing 5 to 40 pounds in the rear facing position, and from 1 year and 20 lbs up to 70 pounds in the forward facing position.

Britax Boulevard is not a compact car seat but can be comfortably fitted in smaller cars the size of a Toyota Prius. I should mention that Britax has discontinued the manufacture of their range of Compact convertible car seats which has a maximum weight of 40 pounds.  The demand for car seats that can be used for longer periods thereby helping parents stretch the investment in a car seat made Britax to discontinue the manufacture of compact convertible car seats.

Consumer Reviews

Before I make any purchase, I like to read what real consumers who have bought and used the product are saying – and Amazon is my favorite spot to check on popularity or otherwise of a product. Britax Boulevard 70 CS, and the later models the Boulevard 70-G3 and the G4 are both attracting rave consumer reviews on Amazon, and surprisingly old and new models are almost neck to neck in high customer satisfaction ratings.  You would expect the 70-G3 and G4 to rate higher being the newer models, but that goes to show the love for Britax convertible car seats amongst parents.

Consumer reviews at Amazon for both models are full of comments like these:

“… This seat is extremely well made and doesn’t take up too much space in our Prius..”

“…It is safe and comfortable and fits very well in the car (we have it placed in the center). Found it $100 cheaper on Amazon than the other stores ..”

“…The best part is that our son loves it. The fabric is soft and comfortable, the side wings support his head when he snuggles against them to go to sleep during long car rides …”

Excellent online Rating above 4.5 stars

At the time of writing this review Britax Boulevard 70 CS, 70-G3 & G4 are selling at highly discounted prices on Amazon with just $10 difference between their sale prices.    I do a lot of my online shopping on Amazon because it is trusted, provide an excellent customer service and runs regular promotions with free shipping.  Be sure to check the prices today.

Cross outCan be more expensive than other brands of convertible car seats, but it is a Britax so I guess you pay more for better quality and features.

Cross outOne consumer with twins commented that the head support pull very easily. I have not been able collaborate this from other sources, and it may well be a case of usage. My sister has twins and I have a fairly good idea what they can get up to sitting next to each other in car seats!
