Product is ok, but could be better. Works best on a flat chair. If you are using it on an old revolving office chair and the seat cushion is already damaged, then this cushion will not be comfortable, your posture will be wrong. I started getting neck pain after few days. Now I am using few layers of cardboard on my revolving chair and now the cushion feels better. Works for 6 months not more than that.

Very good for this price. Can purchase for a comfortable sitting at home or in Car driving (self) b

best product also comfortable for piles patient
