It was Mama's idea
My mom wanted this so if she requests something specifically then it is good. Honor your father and mother so your days will be long on the earth.

Miracle. It's a miracle.
Size: Standard (Medium)
After years and years of searching for a comfortable pillow, I've finally found it! I was hesitant to try latex because I have severe sensory issues and thought it would be weird, smelly and maybe noisy. I really couldn't envision how it would work. The reality is a perfectly bouncy soft pillow that supports your head and neck at just the right height and has immediate bounce back so that when you turn in the night you don't have to waste hours or even minutes fluffing plumping positioning or any other nonsense... You just flip yourself over and go back to sleep. It's a friggin miracle!!! There is a very faint though tolerable and fading scent of balloons. Not too bad for me, but might be annoying to some. Overall, thank goodness I bought this pillow. I'm tempted to replace all my pillows with latex ones but... I don't really need any other pillows now! Maybe I will just so I have spares or something. Granted, it's only been about a week but I expect it to be fairly durable and hold it's quality for quite a while. So thrilled! Just so happy with this purchase! Ten stars, ten hearts!

Very Firm Latex Medium, Appears Well-made
Size: Standard (Medium)
I love latex pillows, used them for decades. Then I got led astray! My neck reminded me I need firm, but soft and bouncy. This pillow is surprisingly firm for a medium. So think twice before ordering firm.

Comfortable but smaller than a standard pillow.
Size: Standard (Medium)
The pillow is bit smaller than standard length wise. It takes a while for the smell to go away. Very comfortable pillow.
