This is a 4.5 star review. The only reason I did not give this 5 stars is that it must be placed just right or it is uncomfortable. But if you get it in just the right position, it is totally comfortable. So much so that it is neutral – you don’t think of it at all, which is a good thing, it just feels natural and right. With a competing sheepskin covered foam and gel pad, I found similar comfort, but the key difference is after sitting for a while and then getting up (I use this while working, and may get totally engrossed in work and not get up for over 2 hours). With the other pad, I would feel stiff and have some butt pain on standing. With the ComfiLife pad, absolutely no stiffness, no discomfort, and no pain! What an improvement! I have only had it for a few days so I cannot comment on the longevity, but for now it is a perfect as I can get… as long as you place it just right. 🙂 ..More
