No. there are two types of car seats. One type is a travel systems which usually comes with a base. The other type do not fit onto prams or pushchairs. Travel systems are removed in and out of the car a lot to click into a pram frame so they have a base to clip onto. Snugglebundl advice is to get a car seat that stays in the car so you are not temped to leave your baby in it for unhealthy long periods for fear of waking him/her.
