Overall a really good junior car seat and has 2 really handy cup holders, nice and wide so great for kids on the bigger side without feeling squished, headrest is fantastic for those that still fall asleep in the car as keeps there head nicely positioned without flopping around, also turns into a booster seat and cant beat the price. Would definitely recommend and buy again in the future if needed.
