Costco is in the process of contacting customers directly about recalled mattresses.
The U.S. Consumer Product Safety Commission issued the recall, involving 48,000 mattresses due to a mold exposure risk, reports CNN. The product was sold exclusively at Costco between January and June in the Northwest U.S. and the San Francisco Bay area.
The commission said the mattresses—made by manufacturer FXI— may have been exposed to water during the manufacturing process. So far, customers reported 541 cases of mold.
The mattresses involved in the recall, the Novafoam ComfortGrande 14 inch and Novafoam Dreamaway 8 inch, were manufactured at FXI’s San Bernardino, Calif., facility earlier this year. The mattresses include twins and California kings.
The model and item numbers can be found on the U.S. Consumer Product Safety Commission’s website.
