Britax updated the B-Safe 35 in 2021 and gave it the Gen2 name. The interior seating area has been opened up, making it roomier for the child. There are also minor changes to the way the lower LATCH connectors are attached to the base and the recline angle indicator has a more concise window, as opposed to arrows pointing to where the indicator should be. There are 3 models, listed below:

Installation Basics

  • If you need more recline than the extended foot on the base can give you, you can use pool noodles. Squeeze the red handle at the front of the base and push the recline foot back into the base before using the noodle(s). The LATCH straps are short; when used in combination with multiple pool noodles and deeply recessed lower LATCH anchors, the LATCH connectors may not reach the anchors easily or at all. Switch to using the seat belt for installation.
  • Pulling the slack out of the LATCH straps is different than on any other seat just because the slack is attached to the center of the base. The leftover strap stands up in the base, but it’s easy to push it down so there’s no interference with the carrier.
  • Lap/shoulder belt installation is slick. Place the seat belt through the belt path, pull the shoulder belt tight and slide it into the red lockoff on the side opposite of the buckle. The only hiccup in doing this will be that the space for sliding the shoulder belt up is a little on the small side; otherwise, the belt slides in easily and stays in the lockoff.B-Safe 35 baseless
  • If installing without the base, you’ll need to use a triangle of taped noodles or a big, tightly rolled towel to keep the carrier level. The curved shape of the B-Safe Gen2 makes it want to slide down as you tighten the seat belt. The B-Safe Gen2 does NOT support a Euro-style belt routing baseless installation.
  • Current trends for rear-facing carseats are anti-rebound bars (ARBs) for energy management. You’ll notice the B-Safe Gen2 doesn’t have one. Bases with ARBs may be purchased separately; however, supply chain issues are causing an issue with availability, so check back and we’ll provide you a link when they’re available.

Center LATCH installations with Non-Standard Spacing:

Britax only allows lower LATCH connector installation of the B-Safe Gen2 in the center seating position when the vehicle manufacturer has designated it as a LATCH location.

Inflatable Seat Belts

Britax has determined that the B-Safe Gen2 cannot be installed with inflatable seat belts found in some Ford, Lincoln, and Mercedes vehicles, and in some airplane seat belts.

Extra bases for the B-Safe Gen2 can be purchased, if needed for $118.99 MSRP.

Fit to Child

Fit to the 4 lbs. preemie doll is excellent with the head pad, which is good since the B-Safe Gen2 starts at 4 lbs. (though we know that not all 4 lbs. seats are great 4 lbs. seats). The preemie doll actually fits to the bottom slots without needing the head pad, but the harness is too loose (see giant pinch in doll’s right shoulder strap). Fit to my 14 lbs. 7 mo. old model was good as well. He’s a tall-torsoed boy and had lots of headroom.

Once the baby reaches 11 lbs., the harness needs to be adjusted to the longest length.

Cover/Maintenance/Ease of Use

Instructions for cleaning the cover are to hand wash with mild soap and water and to line dry. I suggest rolling it tightly in an absorbent towel to get the extra wet out before hanging to dry. Getting the cover off was easy, but tucking it back in around the plastic seat belt guides was tricky. You will have to unthread the harness. And remove the buckle. Sorry.

B-Safe 35 without cover

The slot for the buckle is too narrow for easy removal. In order to remove the buckle—which you must do to switch from the back position to the front position once your child is 11 lbs.—you must turn the metal slide on its side and push it up through the bottom of the seat. It’s pretty standard fare. Except that the slot is too narrow so you can’t actually get enough buckle webbing through to turn the metal slide on its side. It can be done, but not in seconds like on other seats. More like minutes and it will leave you with sore fingertips. Otherwise it’s a top quality IMMI buckle for those who keep track.

Speaking of the harness, it’s easy to adjust the harness tightness. Yeah, you’ll have to manually adjust the harness slot height as your child grows, but you don’t do it often and it saves precious weight on something you have to haul around.

FAA-Approval/Lifespan/Crash Guidelines

The B-Safe Gen2 is FAA-approved; however, the base is not approved for installation on the plane. I suggest if you become very familiar with installing the carseat baseless and leave the base at home altogether. Bring a towel in your luggage to roll up and use to make sure the recline angle of the carrier stays level.

The B-Safe Gen2 has a lifespan of 6 years and Britax follows NHTSA’s crash guidelines of replacing after a major crash only.

Stroller Compatibility

The B-Safe Gen2 uses Britax’s Click & Go system to fit on any of their strollers. The B-Safe Gen2 is available as a Travel System paired with the B-Agile stroller. It is also compatible with all Britax & BOB strollers that work with the original B-Safe model. This includes the Britax Affinity, B-Ready, B-Agile, and B-Agile Double strollers. Note: The B-Agile Double can only accept one carseat. The B-Safe Gen2 is also compatible with the BOB Motion stroller using the Click & Go attachments. With the Britax adapter bar you can also make this carseat compatible with all the other BOB strollers. Compatibility with other stroller brands will depend on whether that manufacturer offers a Britax adapter.

(In all fairness, these aren’t necessarily problems but I list them here to inform potential consumers of specific B-Safe Gen2 issues.)

  • Short LATCH straps may be a hindrance in some vehicles (but just use the easy seat belt install instead)
  • May need extra noodles/rolled towel to get optimum recline, especially when using carrier without the base
  • Buckle is difficult to move from one position to the next


The Britax B-Safe Gen2 is a nice update to the original B-Safe. Child Passenger Safety Technicians will love it for its easy to adjust recline and parents will love it for its ease-of-use. The disadvantages are relatively minor and can be worked around. My only wish is for better covers—the choices are a little bland, though the red is a good red. Still it’s a minor complaint considering. The built-in slide lockoffs grab the seat belt securely, the push-on lower LATCH connectors are what you expect from Britax, and the handle is comfortable in the crook of your arm. All-in-all the B-Safe Gen2 is a commendable and recommendable rear-facing only carseat.


Thank you to Britax for providing the B-Safe Gen2 used for this review. No other compensation was provided. All opinions expressed are those of CarseatBlog.
