The company’s SULTAN and VYSSA crib mattress could create a gap between the mattress and the crib ends larger than allowed by federal regulations. The gap poses an entrapment hazard to infants.

Approximately 300,000 in the United States, and about 44,000 in Canada, have been recalled by the company, according to the Consumer Product Safety Commission.

The Swedish retailer received two reports of infants becoming entrapped between the mattress and an end of the crab. The children were removed without injury.
