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.
