I'm out of the loop, and DD is only 3. What are the better car seats now?
I googled it, but came up with not one consistent #1. I swear some of these lists are sponsored.
This list is in no particular order. Among the reasons for seats being recommended are higher height/weight limits, lower cost (lower than Britax with =/+ features), ease of installation and use, extra leg room for extended rear-facing children (the recommendation is to the limits of the seats, for most kids that gets them to well over the age of 2, but in Britax seats there is very limited leg room). Keep in mind that seats are either outgrown by height or weight, whichever comes first. A seat with a 50lb weight limit and a really tall shell, might be outgrown the same time as a seat with a 65lb weight limit and a shorter shell.
Graco MyRide 40lbs rear-facing, 65lbs forward-facing
First Years True Fit 35lbs rf, 65lbs ff
Sunshine Kids Radian 40lbs rf, 65-80lbs ff
Evenflo Triumph Advance 35lbs rf, 50lbs
Safety 1st Complete Air 40lbs rf, 50lbs ff
Also, installation compatibility plays a factor. In many vehicles, the Radians are difficult to install. But they are narrower, so they're good for 3 across situations. (Like if you have 3 kids in the back seat of a sedan.)
When the new Britax seats are released and we start gathering data on installation and use, get some pics to see how kiddos are fitting in them, etc...then one or more of them might make it back onto the list of seats most recommended. But with the steep price, lack of leg room, still only 35lbs rf, they're not.
