This product doesn't quite deliver what it promises. j) He needs 10 hours. After 2 hours of continuous use, the only cool part of the cushion is on the outer edges - the part you don't normally want to sit on. It also doesn't fully repair itself overnight. I'm not sure what temperature it takes for it to fully repair itself overnight, but the office where I store my pillow overnight runs the air conditioner below 70 degrees. When I try to use the pillow the next day, I'm sitting on a semi-liquid/semi-crystalline mixture, which is uncomfortable. I suggest you save money and look for alternative seat cooling pads.
