You can easily turn your stroller into a travel system with one of our car seat adapters or prams. BabyJogger has car seat adapters available for both the single and double strollers. The Compact Pram is designed to fit on the single strollers that feature the accessory mounting bracket and a full recline or a 2011 and newer City Mini Double, City Mini GT Double and Summit X3 Double, while the Deluxe Pram is compatible with most of the single strollers. (Please note Car Seat Adapters have a maximum weight capacity of 45 lbs - that's the combined weight of the car seat and the newborn, and prams will hold children up to 25 lbs.)
The City Mini, City Mini GT, City Mini ZIP, City Lite, City Elite, and Summit X3 strollers have an increased recline angle to a near flat position to accommodate newborns. That means you can safely lay a baby in the fully reclined seat of these strollers without the use of a car seat adapter or bassinet. While using a Summit X3, never run or jog with your seat fully reclined. Also, please keep in mind that babies should have ample neck support when placed in the reclined seat of a stroller - you can use any number of neck supports sold at baby stores.
