I had the cushion a couple of days ung've tested a lot and but then sent back at the end. This seat cover is perhaps a nice gimmick, but then replaced but no massage. I have it on the sofa so also in a chair tested. The Kries movements are quite nice, but to my mind were the "red dots" then too hard. (And I'm not really sensitive). The heat is not regulated. And just hot.
And like many others, too write: The neck massage ever comes only at the neck, if done correctly up / down slide and then leans her head all the way back. Somehow not relaxing.
