Afternoon dude, its mentioned a few times actually. In the conclusion it stated "The rapid adjustments mean that two people of completely different body shapes can share it and yet both be equally comfortable."
Comfort will always be down to the end user because we are all different shapes, sizes and weights so its all down to your own thoughts which is why we focused heavily more on the adjustment available because that is almost always where the end user will find their own optimum comfort.
I can get the reviewer to add in he fell asleep in his one evening if it might help with the description
