Y’know, my wife got one back when they first came out (and before all the election denying) and she loved it. It was firm enough not to go flat, but soft enough to be comfortable. She had it for a while, and even took it with us on vacation, but we accidentally left it behind at a hotel and didn’t notice until we got home. I ordered her another one, and it was junk. She hated it. It wouldn’t hold its shape, was lumpy, and was horribly uncomfortable. We sent it back and ordered another with the same results. We wound up throwing it away, and she sleeps on a Purple Pillow now.
I read something later that said that after his pillows got popular, he started cutting costs by using substandard memory foam pieces, and the quality tanked. In my experience, that seems exactly right. So I will say that his pillows were really good when he started out, but they’re junk now.
