I bought a Safety 1st Vantage Point Booster Seat for my daughter. It is a carseat that can be used for up to 20 pounds and then you can change it to a booster seat with the seat belt. I loved it so much that I bought a second one for the other car! It has a 5 point harness that can be adjusted with a pull of a string (very easily done for a parent!) The seat is comfortable for my daughter, fits snuggly, and provides the safety she needs. The carseat has a pillow type for the headrest, has arms, and has a lot of padding. It is hard to find a carseat that has enough padding for child to sit comfortably...
