NOTE: I just read that the Britax Marathon 70 was rated #1 in having the most toxic chemicals, so consider this before buying.
UPDATE: Upon further research, I've found that most convertible carseats in the rear-facing position offer little leg space for toddlers and that it is "normal" for kids' legs to bend or rest on top of the back of the seat in which the carseat is on. Rear-facing is still safest for kids under 40 lbs. However, some carseats do offer more leg space than others. We are continuing or search for the right one....Read more ›
According to the HealthStuff.com site, YES, this car seat is considered HIGH on the Toxicity Chart.
And no, I'm not concerned.
It states that there is a large measure of Bromine in the clips on this safety seat.
I looked up what that is used for, and why it's such a big deal.
You know what I found? Bromine is used as a Flame Retardant. You see the importance?
Think about being in an accident, the car in raging hot with flames. You are scared for your child's life, not sure if you can get him/her out quickly.
Then you take into consideration, there is Bromine on the clips so they DON'T MELT in the extreme heat.
Therefor, you un-clip and free your child easily and are away from the vehicle in an instant!
See what I did there? I don't wish that on ANYONE... But doesn't it make sense?
Besides, how many of you see your children chewing on something and getting poisoned by something that's resistant to extreme heat like fire?
This is a worth while seat for the price, and ease of mind.
Why I love this seat:
The seat is VERY easy to install with the latch system and almost as easy with a seat belt. Each latch strap has its own buckle. I installed it rear-facing with the latch in about 5 minutes. (That doesn't include the time it took me to read the manual though - which EVERYONE should do prior to installing any carseat).
The seat has 3 different recline settings for a more custom fit in your vehicle - since backseats aren't all at the same angle. This is an awesome feature.
My daughter's head doesn't droop when she sleeps because I can install this at an angle that keeps it tilted back enough - lots of other convertible seats were too upright when rear-facing.
You can easily adjust the height of the shoulder straps on the back of the carseat by lifting a lever - while the carseat is in the car and while the baby is in the seat.
You can adjust the tightness of the harness with the strap on the front of the carseat while the kid is in the seat - very nice, convenient, and easy.
The rubber guards on the harness make it easy to keep the straps where they are supposed to be and help keep the chest buckle in place.
This seat is very cushy - much softer and more padding than all the others we have owned or used.Read more ›
