Yes, will be double latching. I just found the ISOFIX LATCH points. It seems they can only be used in the right and left outboard seats and not the center seat because the ISOFIX LATCH points may be too far apart from each other.
Some ISOFIX/LATCH*1 equipped child-restraint systems can be placed in the center position and will reach the nearest ISOFIX/LATCH*1 lower anchors which are 406 mm (16.0 in) apart. ISOFIX/LATCH*1 compatible child-restraint systems (with attachments on belt webbing) can be used at this seating position only if the child-restraint system manufacturer's instructions state that the child-restraint system can be installed to ISOFIX/LATCH*1 lower anchors that are 406 mm (16.0 in) apart.
What is the experience with the Chicco Keyfit systems?
