Apple Park, a clothing company that specializes in “environmentally responsible and luxurious products for babies and children," is recalling items from its Bamboo Loungewear Collection after they failed to meet a federal flammability standard.

The U.S. Consumer Product Safety Commission says consumers should immediately stop using the pajamas, which are sold at children’s stores across the country and on Amazon. Federal standards require that all children’s sleepwear and loungewear fit snugly or be flame-resistant.

The recall applies to two-piece clothing sets made from 96 percent viscose, which is an extract from bamboo, and four percent spandex. The commission urges families that have purchased this line of loungewear to contact the San Francisco-based Apple Park for a full refund.

This is the second major recall of a children’s product in the last seven days. Last Friday, IKEA announced a recall of two models of children’s beds, due to a faulty metal rod underneath that could break and cause injury.
