The Food and Drug Administration (FDA) in America say the item may prompt tots dozing in a position that could remove their oxygen.
They are intended to enable infants to rest securely.
In any case, the cushions, otherwise called “homes” or “hostile to move” items, have been connected to no less than 12 passings.
All cases in the US includes tots moving from their sides onto their fronts.
Rest positioners are as yet being sold in stores and online in the UK and US – in spite of the FDA’s wellbeing cautioning seven years back.
They are right now accessible online at John Lewis and Amazon.
Yet, Mothercare, Tesco and eBay have today declared they are pulling back the items, the MailOnline reports.
A Tesco representative stated: “We have expelled these items from our site as a careful step.
“These items were accessible online just, not in-store.
“These items were sold by an outsider on the Tesco site, not sold by Tesco itself.”
A representative for eBay stated: “After late suggestions by US experts, things of this nature will now be denied from being sold on our stage.
“Our group will illuminate dealers and expelling any postings that contradict our approaches.”
The 12 passings connected to child rest positioners in the US occurred in the vicinity of 1997 and 2010.
The FDA said there no most recent figures accessible.
In an announcement the wellbeing guard dog stated: “FDA is reminding guardians and parental figures not to place babies in rest positioners.
“These items can cause suffocation (a battle to inhale) that can prompt demise.”
