An Illinois woman is suing after she says her mother was pinned between her Sleep Number bed and a wall for two days, leading to her death. On Oct. 19, 2014, Rosalind Walker bought a Sleep Number bed in Brentwood, Missouri, according to a civil complaint filed on Dec. 10.

The lawsuit said the mother was pinned against a wall for two days after the Sleep Number bed unexpectedly lowered on her.

The woman who died was between the raised Sleep Number Bed and the wall of her bedroom when the bed "lowered without warning," the suit says.
