Consumers groups applauded the Consumer Product Safety Commission's vote today to adopt the world's toughest crib-safety standards.

The commission voted unanimously to ban the manufacture, sale and resale of the cribs, which have a side rail that moves up and down to let parents to more easily let their children in and out.

According to an Associated Press report, the new standard requiring cribs to have fixed sides would take effect in June. The move by CPSC would also prohibit hotels and childcare centers from using drop-sides, though those facilities would have a year to purchase new cribs.

The CPSC has recalled millions of drop-side cribs in recent years, and it attributes at least 32 deaths of infants and toddlers to recalled models.

Three leading consumer groups -- the Consumer Federation of America, Consumers Union, Kids in Danger and the U.S. Public Interest Research Group -- quickly praised today's vote in prepared statements sent to news organizations.

"This new mandatory standard, the strongest in the world, will ensure that new cribs coming onto the market will provide safe haven for babies and their families," said Nancy Cowles, executive director of Kids In Danger. "We applaud CPSC for their hard work and tenacity in developing and adopting this landmark rule."

Rachel Weintraub, director of product safety for Consumer Federation of America, said the change was overdue. "Parents and caregivers should have peace of mind that when they leave their baby in a crib that their baby will be safe," she said.

Don Mays, senior director of product safety and technical policy for Consumers Union, noted that the durability of recently produced, pre-ban cribs "is appalling and has put many babies at risk." He said new regulations will raise the bar for child safety.
