    Comments about Boulevard 70 - Aztec:

    I absolutely love this car seat. I purchased it for my almost 2 year old (and to put in another car). I have been debating purchasing an additional seat for some time now but the car seat reviews were extremely confusing. It seemed as if as soon as I narrowed down a choice, some other study was released further confusing me. By far Britax received the best reviews for high-end models but some organizations had mixed reviews on traces of elements found in the material making up the components of seats. I finally decided if the component was not one which touched my childs skin (e.g. steel bars) or was something she could possibly ingest, she will be fine. So here it goes, the LATCH system on the Boulevard is awesome and gives one a sense of security with the tether strap. If you decide on getting a seat with the LATCH system, double check your cars ability to secure the seat in this manner. I find it much easier to use the LATCH than the regular seat belt system and faster to set up. There is no way you can screw up installing this car seat unless you are from another planet. The size of the seat overall is considered to be average in my opinion, not too big, not too small. It can easily fit it in a mid-size SUV behind the passengers seat with lots of room to spare. The Boulevard model is light-weight to average, no back breaker here. The material appears to be easy to clean and it is definitely easy to remove and wash. The harness is easily adjusted by squeezing a latch towards the front of the seat and the adjustable headrest in a winner as my child is stretching pretty fast. Another thing I like is that you can add 2 cup holders to the seat (yes it sucks that it is not included and must be purchased separately) one on each side if you prefer. I am considering another cup holder for snacks.

    One thing I must add, I am sure there are other models out there that are just as safe. If I was unable to purchase this due to cost I would have been even more confused as there are a lot of other great seats at lower cost. But in the end, I highly recommend this. I can definitely drive around with my toddler feeling secure.
