She is roughly 15kgs. I really want to buy new as I dont trust second hand carseats lol. Um Would I just be best to get another Maxi Rider or is there something better? Thanks
Unfortunately there just isn't much available in the way of convertible boosters that offer a lot of good features (both convenience and safety wise) as well as high slots. At least with the Maxi II there is the option to use it past 18kg with the additional protecta harness, where as with most other seats on the market there just isn't that option. Have you looked at the S&S Explorer or Maxi Plus seats?
