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

Needs to outgas for a day or two and then its great.
Size: Queen (Mid Loft), Number of Items: 1
Needs to outgas for a couple days, ideally outside on a clothes line. Having said that its the first pillow out of a half dozen Ive bought in the last 18 mos that I can sleep on. Sleeping much better and longer now. Latex foam is the only pillow for me. I swear I searched on here a year or so ago and could not find one.

Goldilocks pillow
Size: Queen (Mid Loft), Number of Items: 1
I tried 5 different latex pillows, 2 from this brand. Most had to much loft and were too firm. This brand has one called extra soft that was comfortable but a little too soft. BUT, I could tell the latex was better so I tried this one. It strikes the perfect balance of support and is not too firm. Compared to all the other brands I would call this one soft/medium as all others "medium" were pretty firm. This one is just right!
