Britax Boulevard 70

  • Increased side-impact protection
  • Lots of features
  • Easy height adjustment
  • High rear and forward facing weight limits
  • Side wings can block child's view
  • Heavy and bulky

Called the seat of choice "if Grandma is buying" by one respected review site, the Britax Boulevard 70 and 70 CS (formerly known as the Britax Boulevard) are two of the priciest car seats on the market, but experts agree that the safety and usability features are outstanding. In addition to all the features of a high-end Britax car seat, the Boulevard adds a custom harness height adjustment knob, increased side impact protection and, in the case of the Boulevard 70CS, a harness that provides parents with an audible click when the child is secure.

A high standard of safety

The Boulevard adds cushioned head stabilizing wings to deep, rigid, foam padded sides that protect against vehicle intrusion and contain side to side head motion. The seat base has cells that compress in a crash, lowering the child's center of gravity to reduce forward thrust. Integrated steel bars strengthen the connection to the vehicle and reduce forward flexing in the seat for greater stability. The seat's energy-absorbing tethers stabilize the top of the seat in both the forward- and the rear-facing positions to reduce the motion of the seat. The five-point harness is thick and sturdy with guards that hold it in place. One new safety feature of the Boulevard 70 CS is a harness alert that clicks audibly when it has reached the correct level of tension to safely secure the child. This controversial feature is described by Britax as secondary to parental oversight, but experts say the security indicator might give parents a false sense of security, warning that parents should always check harness security themselves. One user review stated that the click indicator activates before the seat belt is tightened sufficiently.

Easy to adjust settings

In addition to a no-thread harness, the Boulevard has a rolling adjustment knob that sets the harness at a custom height for an exact fit. The 70 CS model embellishes the front harness adjuster with audible click informing you when the harness is secure. The lower LATCH attachments click on easily, the harness won't tangle and built-in seatbelt lock-offs allow you to install the seat confidently without LATCH connectors.

Soft and comfy, but may be too big for some cars

Like all Britax seats, the Boulevard is plush, roomy and generously padded for comfort. The seat reclines in the forward- and rear-facing positions. But, just as those side wings prevent the child's head from moving in a crash, reviewers say they make everyday riding a bit more restricted. Older children in particular, may rebel against blocked side views and less head room. Also, the Boulevard's sheer size can be problematic. Reviewers say the bulky side wings can pose an obstacle when loading babies into the rear facing position, and owners of small cars are warned to take careful measurements before springing for this seat.

User manual not easily downloaded

No complaints about Britax service were found in our research of the Boulevard 70 or 70 CS. The Britax website offers comprehensive installation instructions for all car seat models, but you have to have the date of manufacturer to download them. All Britax car seats carry a one year warranty against defects in materials and workmanship with proof of purchase. Like most car seats, the seat expires and should not be used after seven years.

The bottom line

You can't argue with the sensibilities behind the Boulevard's advanced safety features. By eliminating as much of the child's movement as possible during a crash, chances of injury are reduced. The price of this increased safety is a more restricted environment for the child. And, in smaller cars, this added bulk just may not fit. That said, experts and parents agree that if you have the space and are not turned off by the price, the Boulevard will see you through with an added sense of security.
