Bench Seat for 1k

Looking for a good bench seat for the 1k, needs to have center slots for a smaller riders harness. I have the UTV Giant middle seat and my daughter will not ride in it, says its to uncomfortable. She is 4 and about 45 lbs. Tried everything to adjust it but the seat just isn’t big enough. Would like a 50/50 split but the only thing I can find with the center slots is twisted stitch and its all one piece. Plus everyone on here says the customer service sucks. Thanks in advance for any recommendations.
