Coop Eden Cool+ Pillow Overview
The Coop Eden Cool+ adds gel-infused fill and a cooling cover to Coop's adjustable cross-cut design, with a shoulder cutout option that lets side sleepers tune loft and shoulder pressure separately.
Our Review
The Coop Eden Cool+ isn't a traditional shoulder cutout pillow, but its ultra-adjustable fill lets you create a lower profile that reduces shoulder pressure. Remove fill until you achieve perfect alignment — many side sleepers find this approach more comfortable than rigid cutout designs. The phase-change cooling cover is one of the best in the industry.
Our Hands-On Experience
The Eden takes Coop's adjustable cross-cut fill and adds gel infusion plus a cooling cover, which addresses the one legitimate complaint about the Original: it can warm up under a heavy head. In side-by-side testing the Eden's surface stayed cooler through the first two hours.
The shoulder cutout version is the one to buy if you are a side sleeper. Combined with removable fill, it lets you solve loft and shoulder pressure independently, which no fixed-shape pillow can do.
It is softer overall than the Original and slightly less structured as a result. At $89 it is the best all-round adjustable pillow for warm sleepers, with the Original still the pick if you want the firmest version of Coop's fill.
What We Love
- 100-night trial — try it risk-free
- Phase-change cooling cover is best-in-class
- Infinitely adjustable fill amount
- Ultra-soft plush feel
- Works for all sleep positions
Room for Improvement
- No physical shoulder cutout
- Requires experimenting to find right fill level
- Softer feel may lack support for heavier heads
- Fill adjustment can be messy

Customer Reviews
Removed half the fill — perfect
I took out about 40% of the fill and it sits at exactly the right height for side sleeping without crushing my shoulder. Plus the cooling is incredible.
How We Tested the Coop Eden Cool+ Pillow
Every pillow we review goes through our rigorous, multi-step evaluation process. Here's exactly how we arrived at our scores for the Coop Coop Eden Cool+ 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.
