Assuming you are referring to the Graco Click Connect car seat, here are instructions on how to remove it:
1. To remove the seat from the base, press the red release button on the side of the base and pull up on the seat.
2. The harness can be removed by unbuckling both sides and lifting up on the shoulder straps to loosen them from the slots in the back of the seat.
3. To recline the seat without the base, first adjust the foot prop if necessary, then locate two red buttons on either side of where the back of the seat meets
the bottom cushion - press these in simultaneously and lean back.
