The new Elite 80 Air from Safety 1st, (a Dorel subsidiary) addresses these problems brilliantly, and quite frankly, hit it out of the park for the 3-in-1 model. While it still will not be the only seat a family needs to buy, I can comfortably say that it will last most children from birth to age 8, and after that, a backless booster is only a few dollars.
On September 12, 2013, Dorel annouced a recall of certain Safety 1st and Eddie Bauer car seats. The affected seats are mislabeled with the stickers notating the rear and forward facing belt paths reversed. This recall does not affect their crash performance, however the seats must be installed using the correct belt path.
*This seat has been discontinued and replaced with the much easier to use, Safety 1st Grow and Go*
The Alpha Omega Elite. Utter those words to any Child Passenger Safety technician and then just wait for the sigh of frustration and the exasperated look on their face.
