I just got a new roho quatro cushion and set it up today and sat in it most of the day after i got out of the chair both areas were my bones are were all the way down and don?t come back up? It was fine when i got it checked when i was sitting up and my skin was fine just the cushion in print on my butt. I thought the cushion nubs are supposed to be up and inflated all the time? I do have a very boney butt. Any information would be great!
