I Sleep With 5 Pillows Every Night, But This One Is My Favorite

My bed has always been my sleep oasis—and I'm extremely peculiar about its set-up. I need soft, cooling sheets, a temperature-regulating duvet, and at least five pillows to support a night of quality shut-eye. And I wish I was joking about that last one.

If you've ever scrolled through Amazon's best-seller page for pillows, then you've probably come across Coop Sleep Goods. The brand's original pillow has racked in more than 55,000 reviews from shoppers who can't get enough of the customizable design.

But the brand's offerings go far beyond pillows; it also sells comforters, mattress toppers, sheets, silk pillowcases, and even a pet bed. The common denominator across every product? High-quality materials with an adjustable element for customization.

As someone who runs warm, I hadn't tried many of Coop's products previously. I tend to lean towards items with cooling technology, which helps regulate my body temperature. After all, research shows1 heat exposure increases wakefulness and decreases deep and REM sleep—and we all know the negative health effects of low quality sleep.

When the brand offered to send over a few products to test out ahead of the launch, I jumped on the chance to try the new cooling version of Coop's original pillow, a pair of new silky sheets, and a crescent pillow specifically designed for side and back sleepers.

After making my bed over with the Eden Cool+, Eden Cool+ Crescent, and The Cool+ Sheet Set, I spent one month testing out the new releases. This included washing the sheets at least twice, as well as running the machine washable covers through the wash.

The cooling version of the Eden Cool+ Crescent takes everything people love about the original version—adjustable fill, dual-sided support, and an ergonomic shape–and improves upon them with cooling technology.

Each pillow has a cool-touch fabric cover wrapped around a heat-wicking inner liner filled with Oomph™ Cool+ fill. The gel memory foam and microfiber blend is 50% more breathable than the original Oomph™ fill—and it's GREENGUARD Gold and CertiPUR-US® certified. The dual-sided design also has a ventilated phase gel layer on one side, which adds extra firmness and further draws heat away from the body.

Like all Coop pillows, it comes with a half pound of extra fill, which you can add through the 2-inch zip opening. The pillow arrives compressed and rolled in a box with the extra Oomph™ fill added into the bag. When you unbox the pillow, you're immediately greeted with certifications on the packing.

A funky shape is the pillow's most obvious differentiator. Designed specifically for side sleepers who also occasionally roll on their backs, the ergonomic pillow has a crescent cut-out along its bottom.

When you lay on the pillow, it nestles between your head and shoulders, reducing the gap between your neck and pillow. This ensures you get the right amount of support to keep your cervical spine aligned throughout the night.

It sounds dramatic, but I can feel the support difference when I cuddle up with this pillow. I typically layer at least two peoples to get a similar cradling effect for my neck, but I've found the crescent shape offers the same support without excess bulk.

As mentioned, this pillow is optimized for heat distribution, and you can tell. When I touch all of my pillows outside of their cooling pillowcases, the Eden is noticeably chillier than the rest.

Initially I only added extra fill to the pillow to see how easy it was to customize, but I realized the added fill actually made a huge difference. My head felt a little more lifted, putting my neck at just the right angle.

I continued to experiment with adding and removing fill until I reached my Goldilocks point. We talk a lot about keeping your cervical spine in line in our sleep content, but it was shocking to discover how different just a tiny bit of fill could make a pillow feel.
