This will come as no surprise to most of our readers. Length isn’t everything; it’s the width that tends to be be an issue. Take, for example, these two towering titans:
The one on the left measures an astounding 20 inches at its widest point, while the one on the right is even wider at 21 inches! Every situation is different, of course, so depending where they are placed, being so wide may or may not be a problem. Also, parts of them are narrower, so they may mesh differently with adjacent models. The Graco My Ride 65 (left) and Britax Advocate CS (right) are competitive in many regards and also share a distinction of being among the widest convertible seats on the market.
