Title: Actually Works - not like all the rest
Review: This is a great cushion. It has a zip-off removable cover. It is light, thin, wedge shaped, and does a great job. Mine has one side of non-slip material, and the other a vinyl type material. It relieves pressure on the tailbone and allows me to sit comfortably in front of my computer for hours. Better than the custom cushions that I had made for me.
