This inflatable cushion has been updated for some time its place on my desk chair and I must say it is really good. Of course, it can not perform magic, still perform miracles, but I notice quite a difference. When I had the new Balance Fit, I thought it was super exhausting more than 1 hour to sit on it and in my back, it has pretty crunched and geknackst. In the evening I always had a limp I-today-sports-made feeling in the back. Over time, however, this has been and now I sit easily up to 5 hours or longer (at busy days) on the pillow. However, with the small nubs upward rather than with the longer. In the longer naps me sometime asleep the buttocks and getting up is a painful undertaking. By contrast, but you can hang a cloth or towel also easy, which dampens a bit. Thank you from me and my back;)
