The maker of an activity center for young children has recalled the toy because it can come loose and fall, posing a hazard to children. The cap on one end of the Exersauser Triple Fun Stationary Activity Center, when used in stage 3 as an activity table, can loosen and fall, Evenflo and the U.S. Consumer Product Safety Commission said. Evenflo has received 11 reports about the problem; nine resulted in minor injuries. The recalled activity centers were made between October 2006 and December 2008, with the model number 6231711. Consumers should stop using the activity table in the stage 3 position and contact Evenflo for a free replacement end cap, the CPSC said. The product can still be used in stages one and two, Evenflo said. Consumers can contact Evenflow at 1-800-233-5921 between 8 a.m. and 5 p.m. ET Monday through Friday, or visit the firm's Web site at www.exersaucertriplefun.com.
