Average pillow that might be great for some folks, not for me
Color: White, Size: Queen (Pack of 2)
I should have know this would be like every other pillow I've ever ordered. It's too puffy for me. No give. It claims to offer better support for side sleepers but instead it's giving me kinks in my neck. Not for me. Not adjustable. Not versatile. Standard materials. White. Can't speak to washability and durability as I have had it long and haven't washed it. fair price for two standard pillows. I really wish all these bedding companies would stop rolling and vacuum sealing pillows and such.

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.

Didn’t hold its shape after 1 month.
Item Package Quantity: 4, Size: Queen
been using this pillow for about a month now, and here’s my honest take. At first, it was super comfortable — soft, supportive, and perfect for getting a good night’s sleep. It gave great neck support and felt like a solid upgrade. But after a few weeks, I did notice it started to lose its shape a bit. It’s still comfortable, just not as supportive as when I first got it. I find myself fluffing it more often now.
