Casper: Original Pillow

Pillow-in-pillow design - A supportive inner pillow sits inside a softer outer one. Instead of choosing between firm support and a soft surface, you get both — structure underneath, cushioning on top. Casper designed it with neck pain in mind.

Down-alternative microfiber fill - Nearly a billion fine polyester fibers that shift as you move, so the pillow keeps working whether you're on your side, back, or stomach — and through the night as you change position.

100% cotton percale cover - Percale is a plain, tight weave with a crisp hand and real airflow, which is why it feels cooler than sateen or microfiber. Combined with the fiber fill, it mimics the airy softness of down without the price or the allergens.

Gusseted, 2-inch side panel - holds the pillow's 9" height at the edges rather than tapering toward the sides.

Standard — 18" × 26" · fits a standard or Queen pillowcase

King — 18" × 34" · requires a King pillowcase

Mid-loft, 9" uncompressed, with a 2" gusset.

Nine inches sounds tall, but fiber compresses substantially under weight — the sleeping height is considerably lower than the uncompressed measurement. That's what makes it work across all sleep positions rather than only for side sleepers.

Subject to Casper's 1-year limited pillow warranty against manufacturing defects. Normal softening from use and damage from improper care are not covered.

Pillows cannot be returned once opened, for hygiene reasons.
