Okay, here's the situation... I have a Britax Pavilion that is currently rear-facing and installed using the LATCH system. The seat has a "Versa" tether system that is supposed to add stability to installation. The tether must be locked into an anchor system, which either exists on the floorboard of the car (so the tether would go from the back of the carseat to the floor) or behind the headrest of the actual seat in the car. My car only has anchors in the second spot, behind the head rest. Anchoring the carseat to that anchor once we move to forward-facing makes a lot of sense. BUT anchoring the seat to that anchor position when it is rear-facing is a big mess. First, the tether has to wrap around the carseat, past DD, to the anchor, which seems like a strangulation hazard and which means I have to undo the tether every single time I get DD in or out of her seat, which is a HUGE PITA. Second, because of the way the seat sits rear-facing, attaching the tether actually seems to make the seat less stable because it lifts the seat off of the actual car's seat in the back. Britax suggests using the tether, but I am curious to hear from real life users - do you actually use the tether in this position???
