Remarkable and impressive pillow
Size: Standard (Medium)
The pillow came quickly and was what was expected. After 6 months of chronic neck pain, one night on this pillow has made a world of difference. Please buy one of these if you are on the fence. They are wonderful. Highly recommend.

Not any more breathable than other pillows
Size: Standard (Medium)
I got this in hopes that it would be cooler than other pillows but it seems to hold the same amount of heat.
Additionally, as a side-sleeper, it is too thick for me. It is however pretty comfy and seems to be made out of quality material.
As other reviews stated, it was smelly at first but that went away within a week.

Great pillow
Size: Standard (Medium)
I love latex pillows. They are bouncy but yet soft. This is my second one. This one is the medium and my first soft. I use soft on top laying watching tv and sleep with medium. No neck pain at all. I have always loved these from years ago. Will always use these only.

Lost its firmness way too quick
Size: Standard (Medium)
I’ve used latex pillows almost my whole life & this has to be the worse one yet. These pillows usually last me years, I’ve only had this one about 4 months & it’s already gotten flat causing me neck pain. When I first got it I was skeptical since it was already very flat compared to what you get in store but I gave it a try anyway. I slept good for the first 2-3 months since the firmness was still there but now it’s not holding my neck up at all. On top of that the smell was stronger than usual and took about a month to go away. I’ve gotten cheaper latex pillows in store that have lasted me longer but I needed one fast so I decided to order this one.. Would not recommend.

EXCELLENT CHOICE
Size: Standard (High Loft), Number of Items: 1
ABSOLUTELY AWESOME ! I TRIED A MEDIUM SOFT PILLOW FROM ANOTHER COMPANY FOR $35 LESS, BUT IT COULDN'T STAND UP TO MY NEEDS OR EXPECTATIONS. THIS STANDARD SIZE PILLOW THAT IS "FIRM" AS OPPOSED TO SOFT OR MEDIUM, IS FANTASTIC FOR MY HEAD AND NECK. IT IS KEEPING MY CERVICAL SPINE ALIGNED WHILE I SLEEP AND RELIEVING THE HEADACHES THAT I HAVE BEEN HAVING DUE TO MY DEGENERATIVE DISC DISEASE IN MY NECK. GREAT PILLOW AND WELL WORTH THE EXTRA MONEY. THANK YOU !
