Doesn't work;  Purple customer service won't respond to allow me to return
I actually bought this direct from Purple so I would be sure about the 30 day money-back guarantee; since customer service won't respond to my email asking to return it, I don't know how much that actually gained me.<br />I honestly don't understand why people love this.  You sit on it, and the whole structure just collapses/deforms to the side. So you still end up with pressure points.  I guess I thought the structure would compress vertically under weight, so, like with memory foam, you end up with equivalent pressure at all points.  But it doesn't.  It just collapses sideways.<br />I also actually collected some observational data. Without any cushioning, the pressure areas when sitting generate red blotches on the order of 3 inches by 1 inch; with this cushion, the red blotches are maybe half that. However, I also bought a memory foam cushion, and there is no redness at all with that.
