HOUSTON -- A Houston-area couple sued a crib maker after their daughter died while sleeping in one of the company's products.

"She was just precious, my princess," Tami Arceneaux told Houston television station KPRC.

Arceneaux never imagined putting her 7-month-old daughter, Royale, to bed in her Simplicity crib would put her life in danger.

Her lawyer said the crib did not come with instructions. The family wrote Simplicity and had a manual mailed, but when it arrived, the lawyer said there was a major problem.

"There's no mention anywhere on this page telling consumers installing the drop rail that there is a top and bottom," attorney Mark Weycer said.

"I feel like we followed the instructions to the best of our ability," said Arceneaux.

Without knowing it, the Arceneauxs put the drop rail on upside-down. Because of that, they said, a hinge broke. That allowed a gap between the mattress and the rail. That gap is where they said Royale suffocated to death with her head against the mattress.

Last week, the Consumer Product Safety Commission recalled more than 1 million cribs made by Simplicity, also using the Graco logo, because the drop rail can become detached.

"If you are a parent who has this type of crib, check immediately to see if it's one being recalled. If it is, don't put your child in that crib tonight," said Patty Davis of the CPSC.

Other parents around the Houston area, such as Tammy Ellison of Nassau Bay, said she felt lucky nothing happened to her son. Nine-month-old Dylan has been sleeping in his Simplicity crib since he came home from the hospital.

"It's scary. My crib's put together right, but I don't feel it's safe for him," said Ellison.

Dylan will be sleeping in his playpen until the company sends her a repair kit. She said that could take four to six weeks.

The recall may be too late for Royale, but her mother said it's still a blessing.

"Royale is gone. I can't bring her back. I wish I could. It helps me sleep at night now that this is recalled, to help other families," said Arceneaux.

CPSC said at least two babies have died in Simplicity cribs from the defect, and seven more had been dangerously trapped. There were more than a dozen different models being recalled.

The recalled Simplicity crib models include: Aspen 3 in 1, Aspen 4 in 1, Nursery-in-a-Box, Crib N Changer Combo, Chelsea and Pooh 4 in 1. The recall also involves the following Simplicity cribs that used the Graco logo: Aspen 3 in 1, Ultra 3 in 1, Ultra 4 in 1, Ultra 5 in 1, Whitney and the Trio.

The recalled cribs have one of the following model numbers, which can be found on the envelope attached to the mattress support and on the label attached to the headboard: 4600, 4605, 4705, 5000, 8000, 8324, 8800, 8740, 8910, 8994, 8050, 8750, 8760, and 8996.

The cribs, which were made in China, were sold in department stores, children's stores and mass merchandisers nationwide from January 1998 through May 2007 for between $100 and $300.
