Easily convert your Tri Mode or Zee to a pram by adding the bassinet. It’s a great alternative to using the car seat. The bassinet allows a baby to lay flat and have room to move around. The added sit up feature allows baby to sit up in the bassinet and take in the world around them extending the period of time you can use it. When it is time to stop using it and move into stroller mode, simply take off the bassinet and put the fabric back on the frame and you’re ready to stroll.
