We bought and tested the BabyBjorn One Air Baby Carrier along with thirteen other of the best baby carriers. We put each of them through extensive testing to determine which would score the highest. The One Air had fairly average scores in the versatility, usability, and comfort categories, with a lower score in design quality.

The BabyBjorn One Air is a backpack style baby carrier. It has a few carry position options and is made of a breathable mesh material. It has some pros and cons that we will dive further into.

How it Compares:
Testing and Research
The BabyBjorn One Air is one of fourteen top-rated baby carriers we purchased to test and compare. We tested each of the carriers on their usability, versatility, design quality, and comfort to determine which was the best baby carrier. The One Air, though an overall good product, did not test the highest in our process for some technical flaws.

Limitations and Complaints
When testing the BabyBjorn Air One, we read through the critical reviews of the product to compare our experience to the complaints. Below are the results:
Review Criticism | Our Experience |
---|---|
Clips are complicated | It did take us a few tries to get used to the clip style as they are not standard clips |
Forward facing flap won’t stay down | We also had trouble getting the flap to stay down, even with the adjustable straps |
Hard to put baby in by yourself | There are several straps that did seem to make it harder to get baby into the carrier |
Adult arms rub against plastic | We did not notice any rubbing on the adult arms |
Bruised baby’s legs | We did not note any injury or bruising to baby from the carrier |
Our biggest complaint about the One Air is the child shoulder straps. The carrier advertises being able to hold children from 8lbs to 33lbs or up to 3 years old. However, when we tested it with a 26lb one-year-old, she was too tall to fit under the shoulder straps. This one-year-old is in a higher percentile for height and is closer to the height of a 2-year-old, but she is still within the recommended range for the One Air.
The shoulder straps that buckle over a child’s shoulders are not adjustable and do not seem to offer much room, so a taller child will quickly outgrow them. There is a disclaimer in the instruction manual that a child can put their arms over the straps if they are too tall for them, but we felt this made baby feel less secure and comfortable. We wish that the straps were adjustable and more conducive to a larger child. We think that this carrier is better suited to a younger or newborn baby rather than older baby, and that an average 3-year-old would not comfortably fit into the carrier as advertised.

Usability
Usability was a higher scoring category for the One Air, though still not the highest scorer of our tested carriers. The instructions were fairly straightforward with both text and illustration directions.
It did take us about seven minutes to get the carrier set up, a little longer than many others. The buckles are a slightly different style than a standard clip buckle, which took some getting used to. However, once we got the hang of the buckles, they are pretty easy to use.

Here’s where the One Air fell in time to set up:

There are a fair amount of straps on the carrier: adult shoulder straps, baby shoulder straps, a waist belt, straps under the arms, straps behind the shoulder blades, and adjustable head support straps. We did find the large amount of straps to be a little confusing and easy to tangle.
Once you get used to the One Air’s strap layout and adjustment system, the carrier does get easier to use. The straps are easy to adjust and there are loops to tuck the excessive strap into to help keep things condensed.
Versatility
The One Air’s versatility tied with its usability score. We did take off a few points for the limitations of the child shoulder straps.

If the child shoulder straps were adjustable, we would have given a higher versatility score to the One Air. Unfortunately, the straps limit a taller child’s use of the carrier. Though again, they are allowed to have their arms over them, we did feel this provided a bit of a security issue.

This carrier does advertise being able to hold kids up to 33lbs. This is not as wide of a range as some other carriers that we tested. The One Air is one of the more expensive carriers we tested (around $200), so with it having a lower weight capacity as well as some complications for taller children, you should weigh out the pros and cons of the carrier to decide if you want to make the investment.
The carrier does offer a few different carry styles: a newborn carry position hold, an inward facing carry position hold, an outward facing carry position hold, and a back carry. These are pretty standard carry styles for a baby carrier and the One Air does not offer any particularly unique holds, like a hip carry.
The carrier has a decent range of wearability for adults, with the waistband adjusting to fit waists from 26 inches to 54 inches. We did not see any options to order a waist belt extender if needed, which is something that many other carriers do offer.
Design Quality
The One Air’s design quality scoring was fairly average. Something we noticed immediately after unpackaging that we did not like was a strong chemical smell from the polyester. The smell died down a bit after being out of the box in the open air for a while, but the odor still tends to linger.
Once again, we do not love the child shoulder straps that buckle onto the parent shoulder straps. The lack of adjustability does contribute to our somewhat low support and security ratings. Without the added security of the shoulder straps, taller babies tend to stick further out of the top of the carrier, potentially adding a fall risk.
Here’s how the One Air ranked in the design quality category:

The carrier is a little bit bulky compared to some of the others that we tested. There are several straps that, though well padded, are a little bit cumbersome. The polyester, though a little bit smelly, is very breathable and the carrier itself is machine washable. There is an adjustable head support, but it tended to pop up even when tightened down in the position for an older baby.

Overall, though we like the breathability and softness of the One Air, as well as how easy it is to adjust the straps, we felt that there were a lot of straps to keep track of. The fabric, though nice and airy, does carry a bit of an odor due to the full polyester fabric.
Comfort
We felt that the One Air was decently comfortable. The soft polyester mesh maintains good airflow to keep both parent and little one from getting too hot. There is not a lumbar support piece on the waist belt, which we wish was included, but the straps are thick enough that we did not notice any back issues. The padded shoulder straps are pretty soft, even if they are a little bulky.
Baby’s weight seemed to distribute pretty well in the One Air. We noticed a little bit of pulling on the shoulders, but not too excessive. The straps are easy to tighten and loosen to customize the fit to your body type.
Our child test subject seemed comfortable in the carrier. Since she was too tall for the shoulder restraints, her arms did rest over the top of the straps. Though this position did not seem to cause her any discomfort, the restraints did seem to get in the way.

The Air One does have an adjustable seat to help guarantee baby’s legs stay in the ergonomic “M” position. This position is very helpful in keeping a child comfortable and, research shows, may help prevent hip dysplasia. When shopping baby gear, it’s important to make sure you are getting a hip friendly baby carrier for your little one’s comfort and safety.
Is the BabyBjorn Air One Worth It?
Babywearing is a common practice in today’s society. It promotes infant and parent bonding and can be a great comfort to small children. But it is vital for a parent to choose the best carrier for their and their child’s needs.
The BabyBjorn Air One costs a little over $200, which we think is a pretty high cost for a fairly standard baby carrier. We like the Air One overall and think it is a good carrier for the right child. However, the combination the lower weight limit, the short child shoulder straps, and the chemical smell of the polyester make us question whether this carrier is worth the high price.
Additionally, though the carrier can be ordered in a variety of colors, there are no included accessories or specifically notable features that make it greatly different than other carriers.
Though there may be more cost-effective options, the BabyBjorn One Air is an overall solid carrier. It has some pros and cons, but if you decide to invest in this baby carrier, you will be purchasing a solid piece of baby gear that can help nurture your growing little one.
