The short answer

Coop Sleep Goods Cool+ Adjustable Pillow comes out ahead by a narrow margin (4.7 vs 4.4).

Higher ratedRanked #1 in Best Cooling Pillows

Coop Sleep Goods Cool+ Adjustable Pillow

4.7

$149

The Coop Cool+ is the clearest upgrade Coop has shipped in years for hot sleepers, combining a phase-change gel cover with 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. It is the pillow to pick if you also want the adjustability of shredded fill, not just 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

Ranked #4 in Best Cooling Pillows

Purple Harmony Pillow

4.4

$179

Purple's Harmony pillow is an engineering-first take on cooling — instead of relying on PCM fabrics or gel coatings, it uses a 360-degree GelFlex Hex polymer grid wrapped around a ventilated Talalay latex core, giving you airflow through the whole pillow body. Reviewers consistently rate it 5/5 for temperature regulation. The feel is unique and not for everyone, but cooling performance is among the best in the category.

Strengths

— GelFlex Hex grid contains 1,500+ open-air channels for industry-leading airflow
— Ventilated Talalay latex core has thousands of pin-holes that further amplify cooling
— Three loft heights (Low 5.5", Medium 6.5", Tall 7.5") fit any sleep position

Watch-outs

— Most expensive pillow on this list at $179 standard medium
— Hex grid feel is polarizing — some find it cradling, others find it springy and odd
— Mesh cover developed pulls in Tom's Guide's month-long test

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.

Purple Harmony Pillow

The most engineering-forward cooling pillow in this lineup — the Hex grid and ventilated latex deliver more raw airflow than the Coop Cool+ or Slumber Cloud UltraCool, both of which lean on surface cooling tech. The trade-off is feel: Purple's responsive bounce-back is unique. Saatva Latex shares a latex core but uses shredded latex (more conforming) while Purple uses solid latex with a polymer grid wrapped around it (more buoyant). Coolest on whole-pillow airflow, less cool on contact than the Cool+ or UltraCool. Cozy Earth Silk feels like a different category entirely.
