If sleep is so important to us, why hasn’t evolution seen humans be able to sleep comfortably while sitting?!(e.g. airplane seats)

Our necks don’t seem able to support the weight of our heads which is fair enough but I’d have thought that by now we’d be a bit more able for it rather than either waking up with a cricked neck, or drooped over ourselves?!

waking up with a cricked neck doesn’t kill you, and waking up without a cricked neck doesn’t help you have more children, so evolution [by natural selection] is not very interested.
