 Sizing and Pricing

The Helix Cool Pillow comes in two sizes:

  • Standard/Queen: $115
  • King: $129

Overview

  • Comfort:   The Helix COOL Pillow features an adjustable design for you perfect level of comfort
  • Temperature:   The Helix COOL cover is made with high-heat transfer fabric which is cool to the touch
  • Smell:  There was a faint smell during unboxing that dissipated within a few hours

The Helix COOL Pillow uses a ultra-cool polyethylene fabric that is cool to the touch and stays cool all night long.  Sleep hot? This pillow could solve all those sweaty nights.

The loft and feel are adjustable with two removable comfort layers made of crushed memory foam and down alternative. Because the pillow isn’t one solid piece it’s easy to fluff and adjust to cradle your head.


Comfort

The Helix COOL Pillow comes with two comfort layers inside, just unzip and remove to find your desired height and feel. Our tester has a smaller frame so as you can see below her head is slightly elevated beyond a neutral position with both inserts of the Helix Pillow. Two inserts will work for side sleeping, but one or no layers would be preferred for back and stomach sleeping.

Depending on your body type a different number of comfort layers may work best for you.

Helix recommends two comfort layer inserts if you are a side sleeper who has broad shoulders or if you like a tall, firm pillow.

If you move between back and side sleeping or aren’t sure which feel you prefer, Helix recommends using one comfort layer in your Helix pillow.

And, for stomach sleepers or those who prefer a plush pillow, Helix recommends removing both comfort layers.


Performance

The Helix COOL pillow is made with the same combination of crushed memory foam and down alternative as the standard Helix pillow. It has a firm and supportive feel which is adjustable by removing or inserting the two comfort layers.

The kettlebell sinks in lightly while the pillow still holds its shape. Because its made with memory foam there is some slight stickiness when the kettlebell is removed but the down alternative helps to mitigate that. 

The average human head weighs 10 pounds. See our 10 pound kettlebell test below.

 


Temperature

The Helix COOL pillow is actually cool. Like, really cool. It’s cold to the touch, and stays cool all night. Plus, it stays cool during our test. Helix uses a high heat-transfer polyethylene fabric that doesn’t hold heat making it tangibly cooler than other fabrics. If you’re a hot-sleeper this pillow could be a game changer for your sleep.

For the infrared test a hand was placed on the Helix COOL for one minute and off for one minute.

Sped up at 3x.

After the hand was removed the highest recorded pillow temperature was 84° which dropped to 73°. The Helix COOL pillow stayed around 5° cooler than other pillows we tested.
