Safety is paramount when Consumer Reports tests strollers because, of course, they carry precious cargo. So when we discovered a problem in our routine stroller tests with the Jané Muum, we immediately contacted the manufacturer and the Consumer Product Safety Commission to make them aware of our concerns.

During the course of evaluating strollers, we perform a passive containment test. The test is designed to simulate what would happen if a small child were left unharnessed in the stroller and was able to slide down without restraint. Any stroller with a tray or grab bar should still allow a child’s torso and head to safely pass under the bar and slide out.

If there is not sufficient clearance between the seat of the stroller and the tray or grab bar, the child’s torso may slide beneath the bar, but his head could potentially be caught up by the bar, posing a strangulation hazard.

Update: On May 24, 2018, Jané recalled about 800 Muum strollers due to this potential risk. For more details, read our full
Jané Muum recall report.

To perform our passive containment test, demonstrated in the video below, Consumer Reports uses two instruments—a smaller one to simulate a child’s torso and a larger one to simulate a child’s head. In order to pass our test, either both instruments must pass under a stroller’s grab bar or neither must go through.

When Consumer Reports performed the passive containment test on the Muum stroller, the larger instrument was unable to pass safely under the grab bar when the stroller was tilted forward, with a removable seat cushion in place. The seat cushion is likely to be used with a smaller child, who needs additional cushioning and support, and who is therefore more likely to be unable to support him or herself. Of the nearly 90 strollers in our ratings, the Jané Muum is the only one to fail our passive containment test.

The company responded immediately to CR and said it was testing a thinner seat cushion to address the issue we identified. We are awaiting these results. It also said the company is in contact with and cooperating with the Consumer Product Safety Commission and is committed to following any government requirements and to serving its customers.

Jané noted that it no longer sells the Muum stroller in the United States, and that Jané USA, a division of the Jané Group, recently closed its offices in the U.S. and remains open only to honor warranty claims. A total of 832 of the Muum strollers were sold in the United States at retailers, including We are not aware of any injuries associated with the stroller.

While we appreciate the timely response from Jané, understand that the company no longer operates in the United States, and acknowledge that only a small number of units are on the market, we worry that families who already own this stroller may still face a safety risk, and because strollers often end up on the secondary market for used baby gear, we have designated the Jané Muum a Don’t Buy: Safety Risk.

What to Do If You Own the Jané Muum Stroller

Because Consumer Reports feels the stroller poses a strangulation risk, we advise anyone who owns the affected model to remove and discard the grab bar. That solution eliminates the risk of strangulation identified during the course of our testing. Alternatively, owners can discard the removable seat cushion.

We will test the company’s proposed fix when it becomes available to consumers. “Whether you choose to remove the grab bar or remove and discard the seat cushion, to prevent the child from falling out of the stroller, always secure the five-point harness, and tighten it for the proper fit for your child,” says Don Huber, director of product safety at Consumer Reports.

In the meantime, owners can contact with additional questions.
