The Joovy Cocoon Enclosed Single Stroller in Black is a stroller-jogger-bicycle trailer all in one! The first time I saw this stroller I knew it was the perfect solution for my family! Simply put, it is the most unique and interesting stroller ever made! Packed with amazing features and made of high quality materials, the Cocoon is the wisest investment for our active family. This multi-function stroller easily converts to a jogger AND a bike trailer. It simply doesn't get any better! It has a cocoon-like compartment where my child sits completely content and out of the elements. Entry is through the zippered door that has a cool mesh window for great ventilation and a vinyl window for when the weather is less cooperative. The kids love the two huge windows on either side that allow incredible visibility and views! The interior has a 5-point harness and plenty of legroom. Inside, there are two mesh pockets for your child's take-along items. It has a 2-position adjustable handlebar to accommodate my husband and me. The Cocoon's pneumatic swivel front wheels offer super maneuverability. The full size 20" pneumatic rear wheels offer a super smooth ride for your passenger and cargo. To convert the Cocoon to a jogger, remove the two swivel front wheels and attach the fixed jogging wheel (sold separately). Parents are raving over the extra-large storage area that has a zipper open/close. There is plenty of room for all of your cargo. The single Cocoon is 27" wide so it easily fits through a doorway or maneuvers wherever there are tight spots. The Cocoon will carry a child up to 60 lbs. and it folds up compactly and is easy to store.
