I wouldn't waste your time on CR for carseats. They don't release their testing methods and tend to not recommend the best carseats.
Anyway, a list of good ones is The Britax Marathon or Boulevard (rearface to 35 lbs. and forward to 65), the Alpha Omega (if you go this route, make sure you get the one that harnesses to 50 lbs, there is an older version that only goes to 40 lbs. and has very short top harness slots...will only last you until about 2 1/2 years old) the Evenflo Triumph Advance (rearface to 35 lbs. and forward to 50) and Graco just came out with a brand new one called the MyRide65 that rearfaces to 40 lbs! and then forward faces to 65 lbs. It is a wonderful seat and will allow your little boy to rearface until at least 2 years old as per the new recommendations of the American Academy of Pediatrics. Oh, and the First Years True Fit is another really good one. It will rearface to 35 lbs. and forward face to I think 65 lbs. All new carseats will rearface until at least 35 lbs. There is a reason for this...b/c it is literally 5x safer to keep them rearfacing to at LEAST 2 years old.
