Purchased this pillow and let it sit out for a few days and flipped it over and waited 2 more days. And it still didn't puff up fully. I'll be returning it
The pillow is not what I hoped for. I had to really work to separate the stuffing inside and then it all went back to this hard lump again which is too high to be comfortable for a side sleeper as advertised. Not happy with this one at all.
