4 sources2 derived$119.2as of Aug 1

For hot sleepers, the Coop Cool+ is the clearest upgrade Coop has shipped in years: a phase-change gel cover over plus-shaped foam that breathes about 50% better than the original Eden. Tom's Guide and HGTV both crowned it the best adjustable cooling pillow of the year, and the 100-night trial makes the price easier to stomach. Choose it when you want the adjustability of shredded fill alongside contact-cooling.

Strengths
  • — Phase-change gel-infused plus-shaped foam keeps the surface measurably cooler than the original Coop Eden
  • — Dual-firmness flip design: one side runs supercooled and firmer, the other softer and cushioning
  • — Adjustable fill with included extra Oomph bag — shape it from pancake-flat to chunky side-sleeper loft
Watch-outs
  • — At $149 queen / $169 king it costs more than most adjustable foam pillows
  • — Cooling sensation fades modestly with prolonged head contact even with the PCM cover
  • — Heavy at over 4 lb queen — re-fluffing the shredded fill takes more effort than a down alternative

Cozy Earth Mulberry Silk Pillow
Ranked #2 in Best Cooling Pillows
Cozy Earth Mulberry Silk Pillow
4 sources2 derived$158as of Aug 1

The Cozy Earth Silk Pillow is the luxury, naturally-cooling option in this lineup: 100% mulberry silk fill inside a premium bamboo viscose shell, with a 10-year warranty Cozy Earth backs against any defect. Cooling here is passive and gentle rather than aggressive, yet reviewers consistently rate it the most comfortable pillow they've ever tested. It suits hot sleepers who want a luxury bedding feel more than engineered cooling tech.

Strengths
  • — 100% long-strand mulberry silk fill — naturally breathable, hypoallergenic, and moisture-wicking
  • — Premium bamboo viscose shell stays cool to the touch and doesn't trap body heat
  • — Plush, weightless feel comparable to a down pillow without the allergens
Watch-outs
  • — Most expensive pillow on this list — $330 MSRP, often discounted to $200-264 on sale
  • — Cooling is passive rather than active; cool-touch sensation fades under a thick cotton pillowcase
  • — Cannot be machine-washed — silk fill is spot-clean and air-dry only

How they stack up

Coop Sleep Goods Cool+ Adjustable Pillow

More adjustable than the Slumber Cloud UltraCool and the Saatva Latex Pillow, both of which fix loft at the factory. Sleeps measurably cooler than the Cozy Earth Silk Pillow once you actually put a case on it, because the Cool+ cover keeps its bite through cotton. The Purple Harmony beats it on raw airflow, but the Cool+ is the only pillow here you can rebuild from a flat 3-inch profile to a 7-inch slab in two minutes.

Cozy Earth Mulberry Silk Pillow

The luxury counterpoint to everything else in this lineup. Where the Coop Cool+, Slumber Cloud UltraCool, and Purple Harmony are engineering-led approaches to cooling, the Cozy Earth is a materials-led approach — silk and bamboo just happen to be naturally cool. Doesn't compete with the Saatva Latex Pillow on warranty (Saatva's lifetime beats Cozy Earth's 10 years) but does compete on feel — both pillows aim for a plush, premium hand. Skip if you want pure cooling performance; pick if you want cooling alongside a luxury sleep experience.
