We bought my daughter a Britax Boulevard two years ago and it has been wonderful! The Britax do tend to be a little bulky but are so worth it. They are also pricey, but you won't have to buy another car seat until your child exceeds 65 pounds! We are planning on purchasing another Britax for my daughter so we can pass her Boulevard down to her brother who is 6 months old and outgrowing his infant car seat. One of the best things about the Boulevard is that is adjustable for height without taking it apart thanks to a knob on the side that you use to move the headpiece and straps up and down. The extra price for Britax is soooo worth it because it can be the only seat you buy!
Hope this helps.
