Chicago-based Kolcraft Enterprises is recalling almost one million portable playpen-cribs over concerns the product poses a fall hazard to children, the U.S. Consumer Product Safety Commission said Wednesday.

The Kolcraft Travelin' Tot Play Yard is one of the products subject to Wednesday's recall. (Kolcraft Enterprises Inc.)The company said the recall includes the Kolcraft Travelin' Tot brand and other similar products sold under the brand names of Carter's, Sesame Street, Jeep, Contours, Care Bear and Eric Carle Play Yards.

About 14,000 of the "play yards" were sold in Canada at Wal-Mart and Toys "R" Us stores, Kolcraft said.

The company said it received 347 reports of sides of the device collapsing unexpectedly, resulting in 21 injuries to young children, including one in Canada.

The recall order said a side rail may fail to latch properly, and can collapse if a child pushes on it.

None of the injuries was serious.

Some of the models involved in this recall were subject to a previous recall in September 2007 due to a strangulation hazard posed by the changing table, which resulted in the death of a 10-month-old child in the U.S.

Consumers should immediately stop using the products and contact Kolcraft for a free repair kit, the recall order said.

Those looking for additional information can contact Kolcraft toll-free at 1-866-594-4208 or visit the company's website at www.kolcraft.com.
