Common certifications to watch for include GOTS (organic cotton), GRS (recycled fill), OEKO‑TEX STANDARD 100, and OCS (organic content). Some down-filled options also reference RDS or other ethical down sourcing.
Care varies by pillow: many list machine wash and tumble dry on low, while others recommend hand wash and line dry or lay flat to dry. Contour pillows often advise hand washing and air drying or laying flat.
Look for no‑shift or anti‑clump constructions, multi‑chamber or three‑chamber designs, gusseted or ergonomic side panels, and double‑stitched seams—these features help keep loft even and reduce leakage or feather poke‑through.
Many list breathable organic cotton shells and open, airy fill constructions that promote airflow. Some specifically mention natural cooling or temperature regulation and do not rely on synthetic cooling additives.
Many listings are marketed as suitable for side, back, and stomach sleepers (multi‑position or universal). Contour/cervical pillows are described specifically for back sleepers and for side‑sleep support using raised sides or cervical rolls.
Packaging varies: some arrive in a recyclable printed box (not vacuum packed) and expand within about 24 hours, while others are vacuum‑compressed—those typically advise gently patting and airing or using low‑temperature drying to help the pillow regain loft.
