Very easy to in install carseat, comfortable for baby.

Out of all the carseats I own, this one is the easiest to in install and seemingly the most comfortable for baby. However, my son gets carsick in it about 90% of the time whereas he barely gets sick in our Graco one. I have noticed it sways right to left a little bit even with the install being 100% tight so I'm not sure if that's the issue.
