UppaBaby introduced its first car seat, the Mesa. The infant seat is only 10.5 pounds and uses a smart secure base that is beyond easy to install (trust me, I tried it and it was simple). With a no-rethread harness, it is easy to adjust, too. The base is solid so it won't tear up car interiors. It is also optimized for preemies with a wedge that better positions babies under 11 pounds. It will hit the market in March.
