sure seems like good use of seating space. I could see the rear facing or 2nd row Baron/Bo seats taking advantage of this option.

Now Seating 5
The innovative 60/40 FlexSeating gives Cirrus owners a whole new level of utility and versatility. With a wider back seat featuring three over the shoulder seat belts for a fifth passenger and ten more pounds of useful load.

You gotta hand it to Cirrus for marketing and product improvements.
They are really trying.
It's no wonder their sales figures are so good.
