Dorel Juvenile has recalled about 20,000 Safety 1st strollers due to a fall hazard.

The fall hazard with the Safety 1st Step and Go Travel Systems occurs when the tray folding mechanism partially disengages on one side when used with an infant car seat attached to the stroller.

The strollers have been sold at Babies R Us and other retailers nationwide, and online at amazon.com, babiesrus.com and Walmart.com from May 2015 through June 2016 for between $250 and $300.

• Model number TR314 is printed on a white label on the back of the stroller seat

No injuries have been reported, but the firm has received 30 reports of the front stroller tray disengaging on one side.
