The Natural Way to Better Sleep.
Color: Soft, Size: Standard(24"×16"×5.5"), Color: Soft, Size: Standard(24"×16"×5.5")
After trying out several latex over the years, the Talatex Talalay 100 stands out for its luxurious comfort, quality materials, and overall sleep experience. Made from 100% natural Talalay latex, it offers a perfect balance of softness and support.
Comfort & Support:
The Talalay latex feels incredibly buoyant yet plush. I found it especially beneficial for relieving neck pain.
Temperature Regulation:
One of the best aspects is its breathability. Latex naturally sleeps cooler than other foams.
Eco-Friendliness:
Another big plus is that it’s made from natural latex with no synthetic additives, making it a healthier and more environmentally friendly choice. It’s also hypoallergenic, which is great for allergy sufferers.
Verdict:
If you're looking for a premium latex sleep surface that delivers both comfort and longevity, the Talatex Talalay 100 is a solid investment. It’s not the cheapest option out there, but the quality and sleep experience justify the price.

Finally sleeping well again
Color: Soft, Size: Standard(24"×16"×5.5"), Color: Soft, Size: Standard(24"×16"×5.5")
Got the standard soft and the height is just right - perfect mix of plush and supportive. My neck pain is basically gone. Love that it stays cool through the night thanks to the little vent holes, and the Tencel cover feels super soft. Holds its shape really well too, no flattening. Packaging felt like a gift. Worth every penny.

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.

Nice and squishy
Set name: UltraCool Pillow, Standard - Soft/Medium Firmness, Item length width: 30.0 Inches
Not really a "cooling" pillow, but better than a standard or or fiber filled pillow. All these types of pillows and other bed linens are initially cool to the touch, but they quickly heat up to match your body temperature. Although the technology currently does not exist to maintain constant cooling, pillows like this are a good compromise for now. It's nice and soft and is a good value for the price.
