2015 XP 4 1000 rear bench/harnesses??

HI All,
New to the Forum as of today. I just got a new 2015 XP 4 1000 and I am looking for suggestions for the best rear bench / harness setup. I have three kids and would need three harnesses or at least a middle harness. The color is Vodo Blue. I have not had much luck or at least the "warm fuzzies" by searching online. Any pointers / direction would be greatly appreciated!
