Bests & Worsts Reviews from Amazon

I bought the Wondergel Original cushion for a non-ergonomic office chair. The first half hour on the cushion is OK but it retains body heat and the waffle pattern gets uncomfortable. I've been using the Wondergel cushion for two weeks now and it has seemed to take some of the strain off of my lower back but I have to get up frequently to relieve stressed thigh muscles and excess heat from the cushion. I don't recommend it.
