Ikea is recalling crib mattresses sold in the United States because of an entrapment hazard.

The recall involves Ikea’s Vyssa-style crib mattresses with the model names Vackert, Vinka, Spelevink, Sloa and Slummer. The mattresses were sold at Ikea stores nationwide and online between August 2010 and May 2014.

The U.S. Consumer Product Safety Commission indicates a gap can occur between the mattress and crib larger than the width of two fingers, making it possible for infants to become entrapped.

Customers with affected mattresses are advised to stop using them immediately and return them to any of the furniture retailer’s stores for an exchange or full refund.
