The all-new Indie Twin Infant Car Seat Adapter makes it easy to latch in a car seat. This optional adapter bar can accept Maxi Cosi, Cybex Aton, and Nuna Pipa car seats to be used on the Indie Twin. While the Nuna Pipa has been tested and approved to be used to accommodate twins, we recommend the Maxi Cosi or Cybex Aton car seats to be used for easier attachment. The Nuna Pipa requires more time and effort when attaching to the stroller. This adapter is also not compatible with 2015 or prior models due to frame re-design. In order to fold the stroller whilst the car seat adapter is installed the seat fabric must be removed. The add-on car seat adapter accessory attaches easily to your Indie Twin Stroller. This car seat adapter has been tested with the listed car seat modes manufactured from 2016 onwards. Please note the car seat is not included.
