You can buy seats that are 5 pt harnesses (that's the important part) that go up to 65 or 80 lbs. There is one that goes up to 65 lbs that is around $100. It's a Safety 1st Apex. Here's a link if you would like to look at it. I've seen it cheaper than this but not sure which website it was. Target : Safety 1st Apex 65 Booster Car Seat - Blue
I think I am going to buy the Sunshine Kids Radian 80. This is the cheapest I've found it. Sunshine Kids Radian 80 convertible car seat - Customer Reviews & Free Shipping! |
