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 !

Goldilocks Pillow!! Queen Medium
Size: Queen (Mid Loft), Number of Items: 1, Size: Queen (Mid Loft), Number of Items: 1
Phenomenal pillow. I'm sure most people will have that trial by error with latex pillows, But I can assure you this pillow is the perfect balance of soft yet supportive, I'm 6" 1" 185 and I find it to be extremely comfortable, I purchased a queen medium, and upon opening it does have a vanilla/latex like smell(Not overly strong , but will dissipate in a few days if aired out, Ill mention this because im sure most people assume medium is hard, This isn't the case at all with this pillow, Its soft and supportive, I cant explain it any better than , It really is a Goldilocks pillow, Not to soft or firm but just right for my noggin. I'll also add my girlfriend liked it so much when she used it the second night, That I doubt I'll getting it back now,. All and all it's a great pillow and worth the money, Here's to many great night's with this Kiss Dream Queen Medium Latex Pillow!

Bouncy and cool
Size: Queen (Mid Loft), Number of Items: 1
I had been searching for a new pillow for weeks, but nothing was calling to me. So many go flat far too fast, and most cooling pillows are lumpy as can be. This one is perfect. Doesn't go flat, gives me comfortable support, and actually keeps cool longer than the average pillow
