⭐️⭐️⭐️⭐️ Adjustable and Better Than Most I’ve Tried
Size: Standard (Pack of 1)
I’m a really tough pillow critic and have a hard time finding one I actually like. With that said, this pillow was better than a lot of others I’ve tried—mainly because you can remove some of the latex shavings to adjust the firmness. I ended up taking out about 20% (do it over a big trash can because the shavings can get messy!).
When it arrived it was too firm for me, which is why I had to take some filling out. Even after adjusting it, it’s still not my absolute favorite pillow, but I do use it every night as a “hug” pillow and it works great for that. I think people who aren’t as picky as I am will probably really enjoy it, especially since you can customize the amount of latex to get it just right.
I’d give it 3.5 stars, but rounded up to 4.

Good Value Latex Pillow
Size: Standard (Pack of 1)
Most latex are horribly expensive and smell strongly. This pillow good for a side sleeper, little odor, med firm.

Great size for vintage pillowcases
Size: Standard (Pack of 1)
Gives good support. And very pleased w/ comfort. Slightly larger than old replacement, but not the over-sized "standard" of 25".

Cool-temperature outer cover
Set name: UltraCool Pillow 2-Pack, King - Soft/Medium, Item length width: 40.0 Inches
The pillows (set of2) are easily fluffed and adjusted to personal desire. The outer cover is cool to the touch. I do not feel "cooler" with the pillow, but it does not get hot like some. I'm a side sleeper and sleep comfortably with the Slumber Cloud. I would buy these again.
Con: pillow cover is slick, so pillow cases slide off.

not cooling for post menopause
Set name: UltraCool Pillow, Standard - Medium/Firm Firmness, Item length width: 30.0 Inches
As a post menopausal person I did not find this cooling at all. The material is memory foam which holds heat but more importantly my head sinks in so that half of it is always surrounded by the pillow, trapping heat. It IS a supportive, soft and comfy pillow. For cooling though, I found it better to buy a firmer, thinner pillow which keeps my head from sinking into it, allowing heat to dissipate.
