The verdict
This is part of our pillow series. The main guide, Best Pillows, ranks every category; this post goes deep on one slice.
Smoother cross-cut foam, 100-night trial, 5-year warranty, GREENGUARD Gold. The safer buy.
Higher foam-to-fiber ratio and higher-grade foam. Feels more like true memory foam.
Gel-infused foam and a cooler cover than either Original or Saybrook.
We don't run a sleep lab. These picks are built from manufacturer specs, aggregated owner reviews, and independent testers (Sleep Foundation, Mattress Nerd, Mattress Clarity, Pillow Specialist). Prices are approximate as of August 2026.

How they feel
Coop Original: smooth, moldable, slightly fibrous
Coop's foam is cross-cut into small uniform pieces and blended with microfiber. The result is a pillow that feels smooth (no lumps), molds easily, and has a slightly airy, fiber-forward feel. It's medium-firm at full fill and softens as you remove stuffing. This is the pillow most "best adjustable pillow" lists rank first.
Saybrook: denser, more memory-foam-like
Saybrook's blend leans harder on memory foam and uses less fiber. Independent testers who've compared the two describe Saybrook's foam as higher grade — with the slow, sinking bounce-back of a solid memory foam pillow — where Coop's reads more like regular foam. If you love memory foam and wish adjustable pillows felt more like it, that's Saybrook's pitch. The trade-off is a slightly heavier, warmer pillow.
Coop Eden: the cool version of Original
Same construction with gel-infused foam and a cover that stays cooler. Softer than the Original at full fill. Worth the $13 premium if you sleep warm.
The differences that decide it
- Trial and warranty. Coop's 100-night trial and 5-year warranty are sold directly and consistent. Saybrook is sold mainly through Amazon and its own site; return terms depend on where you buy. Advantage: Coop.
- Certifications. Both are CertiPUR-US. Coop adds GREENGUARD Gold (low emissions). Advantage: Coop.
- Fill quality. Reviewers who've handled both give the edge to Saybrook's foam. Advantage: Saybrook.
- Cooling. Coop Eden > Coop Original > Saybrook. More foam means more heat retention.
- Lumpiness. Neither is lumpy — both use new foam and fiber to smooth gaps. This is what separates both from $30 shredded pillows.
- Adjustment process. Both include extra fill. Saybrook's measuring tube is a nice touch; Coop's bag is fine.
