Love this thing
Makes sitting on my duff for hours possible. I work at home in an office chair full time (more than full time, actually) and I needed to get up every 5 mins to so to prevent my butt from falling asleep. With this cushion my butt stays awake the whole time and I only get up when I feel like taking a break. Going to get another one for my downstairs office because it kind of sucks to lug it up and down the stairs every day.
