I just ordered it and so far so good, however the royal seems undersized for most chairs and Im wanting for about 3 more inches in length. (I rotated it and the length was perfect but it was just slightly too narrow). As a result there is a gap of unsupported thigh between the edge of the chair and the edge of the cushion. Unclear how big a deal this is yet. They do make the ultimate purple cushion which is about the right size but its about 40% more expensive. This isn't a regular and XL, its more like an XS and a regular, and I don't like that's how its positioned.  If its a problem Ill return it and get the other size. it def seems to be a good product. I would give it 5 stars if it weren't for the size issue. the regular size should fit a regular chair.
