Great for musicians stuck with folding chairs at rehearsals. My back hurts without my Tush-Cush. It is firmer than other foam and just feels good. It overcomes the slope of a folding chair. I find comfort with the bigger size Tush-Cush on my computer chair at home.
Finely, something that works! Years of trying every types of memory foams and soft but firm butt pillows in every shapes and makes. Tushcush is the only one I need.
