Any convertible car seat will provide you with the utmost safety features and convenient options. However, convertible car seats are there only for the purpose of protecting the life of your baby when they travel in a car. What about outside when you decide to have a stroll with your child? Instead of purchasing a singular unit you could opt to go for a complete travel system such as those provided by Graco.
These complete units consist of a car seat base that stays all the time fitted into your car seat, a stroller and a travel set that can be transported to and fro between the car seat base and stroller. They come with many more nifty features such as a cup holder and a few pouches to carry along spare bottles and diapers when necessary. Today, travel systems are all about convenience rather than just safety. Obviously the whole set will cost you a bit more than just the price of a car seat.
You can find out more by reading travel system reviews online. There are many makes and models to chose from such as Graco, Evenflo and Safety First.
