Longer than you may think. You have to take into account that BOff's, like your toon, have a lot of different body types to choose from. Whatever works for your character has to also work for my tall, super buffed Gorn officer as well.

That being said, I agree with you your officer sits pretty high up. But then it's been like this on several bridges for some time now so I think it's not on their priority list as it doesn't affect gameplay (it's a social zone really). As a side note, every chair I sit in my feed fall under the floor. I've made my peace with it though as I rarely sit in my chair these days.
