we have been looking at booster seats for my 3 year old.
I still want her in a 5 point harness.. Britax makes a couple of seats that have a higher height/weight limit. but they are very expensive... The Britax frontier goes up to 80 pounds ..But it is super heavy..like 25 pounds.. And we would need 4 of these seats.. (2 kids x 2 cars...= $1,000)
I am thinking about getting the safety first vantage. I saw it at walmart for $89.50 it is a new seat that has a 5 point harness and uses the latch (the latch is a new requirement so all seats and boosters with a back should have latch.)
The safety first vantage seat goes up to 52 inches and 80 or 100 pounds so it should last until the child is 8 years old .
It is much safer to have the kids in a 5 point harness. So I want mine in a 5 point harness as long as possible..
