Coop Sleep Goods Original Loft Pillow vs Purple Harmony Pillow

Buy the Coop Original Loft if you want a shredded-foam pillow you can open up and tune by adding or removing fill, and you sleep on your side or back. Buy the Purple Harmony if you want a pillow that holds its shape without fluffing, sleeps cooler, and comes in three heights. The Coop has a far larger owner base and a 4.6 rating across more than 13,000 reviews; the Harmony sits at 4.3 from about 330. The Coop's knock is that shredded foam settles and needs re-fluffing, and its cover is polyester and bamboo rayon rather than a cooling knit. The Harmony's knock is the latex-and-grid core, which is spot clean only and less adjustable than loose fill.

• Choose the Coop Original Loft if you want to add or remove fill to dial in loft, you move between back and side sleeping, and you want a machine-washable cover and inner pillow.
• Choose the Purple Harmony if you want a springy latex-and-grid pillow that resists flattening, sleeps cooler, and comes in low, medium and tall heights.
