she is, 5'9. i had her scoot all the way down so she would fill the foot-box so you could see it better in the pic.
not sure what the max height is, but i'm 5'11, and if i scoot all the way into the footbox(or close) i have max upper body room, and my shoulder is close to the lower pull tab while the other pull tab is up even with or just past my head. if i want, i can slide up toward the head end by at least 6" and still have plenty of head and shoulder room. i normally have enough to where i can throw my left shoulder up over and behind my head and my elbow not hit the netting. i don't know if you could do this as easily as i do being 4"shorter, but seriously doubt your head or feet would be protruding into the side of the hammock like you're accostomed to.
