The Baby Trend Sit N' Stand Double is a tandem stroller that accepts 2 child car seats at a time and has all the features of the standard Sit N' Stand strollers. There are 2 different seats or you can place your own car seats inside. The seats come equipped with 5-point child resistant harnesses. Kids can sit in front and rear seats of the stroller or stand on the rear platform. The kids even have a removable/ swing away tray with a cup holder of their own, while you have a covered tray with 2 cup holders. An extra large storage basket hangs below the seats and there's a foot activated break for extra safety measures. The front and back seats of the stroller, without car seats, are recommended for kids who can sit upright unassisted, at 40 pounds or 40 inches tall. The jump seat is best suited for kids who are at least 2.5 years old or weigh 40 pounds. Also included is a pair of Baby Trend Flex-Loc Infant Car Seats and Bases.
