The stroller comes in two pieces, the chasis and the seat part. You lift the seat and set it on the chasis where it clicks into place. It can be placed so the child faces forward or so the child faces you. We use it rear facing so my daughter can see us. The harness is very sturdy with nice padding and easy snaps. Overall it is a heavier stroller, you take it apart to fold the chasis and disconnect the seat. If you have an SUV you can leave it whole to throw it in the back. Be prepared, this is a Big stroller. I didn't realize how big until ups dropped off the boxes. Overall it is a great stroller, very sturdy and well made. It comes with a matching diaper bag, soft sleeping bag insert and an outer "boot" cover to put over the foot section of the stroller. I wish I had this from when my daughter was born, it would have saved us a lot of money in the long run, we bought all of the accessories separately with our first stroller purchase. (this is our second stroller)
