Our Review
The Coop Eden is the cooling sibling of the brand's bestselling Original Adjustable. It uses gel-infused cross-cut memory foam blended with microfiber, wrapped in the same breathable Lulltra bamboo-derived cover, but tuned to sleep noticeably cooler than the Original. Like every Coop pillow, the fill is fully adjustable through the inner zipper — add or remove handfuls until the loft matches your sleep position — and an extra half-pound bag of fill ships in the box. In our testing it ran cooler than the Original and most shredded-foam competitors, though hot sleepers in warm climates may still prefer a dedicated grid or latex design. It's GREENGUARD Gold and CertiPUR-US certified, machine washable, and backed by Coop's 100-night trial and 5-year warranty. Side and combination sleepers who overheat on traditional memory foam are the sweet spot.
What We Love
- Gel-infused fill sleeps measurably cooler than the Coop Original
- Fully adjustable loft — extra fill included in the box
- GREENGUARD Gold + CertiPUR-US certified foams
- Entire pillow is machine washable
- 100-night trial and 5-year warranty
- HSA/FSA eligible
Room for Improvement
- Still a foam pillow — extreme hot sleepers may want latex or grid designs
- Requires occasional fluffing to redistribute fill
- Softens slightly over the first month as fill breaks in

Customer Reviews
Solved my night sweats
Owned the Original for two years and loved everything except the heat. The Eden fixed it — same adjustability, but I no longer flip the pillow at 3am. Took out a little fill for side sleeping and it's dialed in.
Second one we've bought
Got one for me, then my wife stole it, so we ordered a King for her. The extra fill bag is a nice touch — she likes hers overstuffed. Washes well too.
Coop Eden Pillow: Lab Results & Long-Term Testing
Tested September 3, 2026 by BT/MR. Verified on coopsleepgoods.com on September 3, 2026.
Measured in our lab
Eden is the gel-infused, cooler-running version of the Original with a slightly softer fill blend. We tested it head-to-head against the Original on the same rig.
| Metric | Result | Category avg. | What it means |
|---|---|---|---|
| Loft, factory fill | 5.7 in | 5.0 in | Same tall factory loft as the Original; same fix — pull fill. |
| Surface temp rise (60 min) | 4.6°F | 6.4°F | 1.2°F cooler than the Original. Real, but it's a gentle edge, not an active-cooling pillow. |
| Time to return to ambient after head lift | 3.4 min | 5.8 min | The practical benefit: flipping to a cool side actually works here. |
| Loft loss after 60 nights | 5% | 11% | Effectively tied with the Original. |
Our long-term sleep log
Same 60-night protocol, run by a self-described hot sleeper who wakes at 3 a.m. to flip the pillow.
Night 1
Softer initial hand-feel than the Original; the gel foam is springier under the ear.
Week 2
3 a.m. flips dropped from most nights to roughly two a week.
Night 60
No packing, no odor retention. Cover washed four times with no shrinkage.
Care, washing & durability
Care is identical to the Original: cover in the wash, fill bag air-fluff only. Eden's fill is slightly softer, so it benefits from a firmer daily fluff to keep the loft even across the pillow.
The Eden costs about $20 more than the Original. If you don't sleep hot, that money is better spent elsewhere; if you do, the measured 1.2°F difference and the faster reset between flips are what you're buying.
The bottom line
The Original with a cooling tax. Worth it for hot sleepers who flip the pillow at night, unnecessary for everyone else.
How We Tested the Coop Eden Pillow
Here's exactly how we arrived at our scores for the Coop Coop Eden Pillow.
Multi-Position Testing
Each pillow is tested by panelists in side, back, and stomach sleeping positions. We measure loft, compression, and neck alignment across body types.
Loft & Support Mapping
We measure initial loft, compressed loft under a standardized head weight, and rebound time to quantify support consistency throughout the night.
Temperature Regulation
Surface temperature is tracked with thermal sensors over 6 hours to evaluate cooling claims and heat retention for different fill materials.
Shape Retention Testing
We simulate 6 months of use with 5,000 compression cycles and measure loft loss, clumping, and fill migration to project long-term performance.
Hypoallergenic & Value Review
We verify hypoallergenic claims, assess cover removability and washability, check certifications, and compare price-to-quality within the pillow category.
