The double stroller offers extra grow-with-me value: it's a conventional tandem stroller that converts to a Sit 'n Stand when your child is ready.. Exclusive One Step Ahead Features:. Solid rubber tires - smoother and more durable than standard dense foam tires (a must when pushing more than one child)! They handle turns much better and will never go flat. Exclusive upholstery pattern - with mesh flow-thru fabric in the head area for comfort. Extended adjustable shade canopy - for more sun protection (on the double stroller, only the front seat has the extended canopy) . Compatible with many infant car seats, including: Baby Trend, Cosco Designer 22 and Arriva, Peg Perego, Evenflo Cozy Carry, Portabout and On My Way, Century Vante, and Graco Snug Ride. Easy one-hand folding mechanism. Jumbo storage basket. Removable front tray. 5-point harnesses. Locking front swivel wheels and rear foot brake. Surface wash covers with mild soap using sponge or cloth. Rear platform is intended for a child at least 2½ years of age and less than 40" tall. Love the idea of a Sit n Stand...eventually? The Double is for you. Use it as a tandem stroller until your older child's ready, then convert the rear seat to "big kid" standing board/jump seat by simply removing the rear seat. Jump Seat pad not included. . Product Dimensions:. Folded: 38"L x 20½"W x 15"H. Seat: 14"W x 16"H. Platform: 13"L x 8"W. Seat pad not included.
