Thanks! Safety is a concern, but only that I want to be attaching it correctly! If that is actually the correct way, then I actually prefer that it doesn't have the bar. Then I easily have the option to use the car seat or just the stroller (or the bassinet I got on Craig's list!).
in my opinion, the attachment for a maxi cosi or cybex for any stroller is better than all of the others bc it snaps in front the sides. it sounds like you did it exactly right.
