Kolcraft Stroller

I just bought a brand nearly nine Kolcraft contours options 3 wheel stroller, but it did not come with the adapter for car seat. Is this the same card as the tandem stroller? I do not want to order online if I know it's the same.

Normally, we buy the car seat base first and then there's the stroller can put your car seat for him.

stroller is completely different from a car seat.
