These are very thick pillows.
Item Package Quantity: 2, Size: Queen
Exactly as advertised. They are very firm and very thick. They're too thick for me to be able to use as bed pillows. However, they seem to work pretty well as cushions in my papasan chair on top of its normal cushion also work very well as decorative pillows. I'm still giving them four stars because they're exactly as advertised and they seem well made. My only complaint is that they're just too thick. And that's definitely not the fault of the pillows or the pillow maker.

Neck posture/sleep pain improvement
Item Package Quantity: 2, Size: King
Pleasantly surprised. Only had for a week now, but bought to replace these old bamboo pillows that were so flattened it was causing shoulder pain or neck tightness maybe. But that has already improved my sleep just from using this week. Ordered the kings, they come vacuum sealed and so I opened and they sat for approx 24 hours or close enough. They didn't appear as puffy so I was a little doubtful but I punched and fluffed them myself and they were good. They have improved the quality of my sleep so far. They are soft and sounds weird but it's almost like your head weight or fluffing them activate it to be fully expanded afterwards. I like them, they're comfortable for me as a mainly side sleeper/sometimes back sleeper.
