We love our ChiBebe so much that I bought one as a baby gift for my boss and managing broker as well! Things that are great about it: it has the zippered interchangeable seats for easy cleaning and to swap out from the one with the harness to the one with the regular seat; it has a tear dropped shape where there is a bit of a peak near where the baby is placed so that you can maneuver the seat to either be more inclined or less; and the zippers have locks that help to keep them in place, preventing them from accidental opening.
We love our ChiBebe and know you will too!!!! It is a genius design!
