I find this harness terrible (tried model 2018). It does not have shape that would match body curves - there is a lot of space between harness and lower back, so there is not enough support for your back. I've tried many seat harnesses and the best are: Dakine Chameleon, Ion Echo Seat, Prolimit Rambler. All of them provide proper support for lower back.
What the main difference between a previous 2014 model?

Unfortunately my experience as well. 2018 fusion did not shape to my body, not very comfortable all together....
