Four major retailers – Amazon, Buy Buy Baby, Diapers.com, and Toys R Us/Babies R Us – have voluntarily decided to recall “Nap Nanny” portable baby recliners after at least five infant deaths and dozens of reports of children nearly falling out of the product.

The CPSC warned parents and caregivers that the Nap Nanny contains defects in its design, warnings and instructions. The agency said the product poses a substantial risk of injury and death to infants.

According to ABC News, the product was created by mom and Philadelphia sportscaster Leslie Gudel, who sold it through her company, Baby Matters. CPSC said it had been negotiating with Baby Matters for a mandatory recall, but Gudel refused to go along, contending the product is safe.

CPSC spokesman Scott Wolfson praised the companies for their actions, saying in a statement, “the retailers were great. They were not obligated to carry out this recall.”

The recall includes Nap Nanny Generations One and Two, and the Chill model infant recliners. Five thousand Nap Nanny Generation One and 50,000 Generation Two models were sold between 2009 and early 2012. About 100,000 Chill models have been sold since January 2011.

CPSC has urged consumers to return the Nap Nanny if they bought it from one of the retailers now voluntarily recalling the product.
