by Casper Original Pillow Review 2026: Sleep Lab Verdict
Editor's Pick — Saatva Latex Pillow. Casper's Original is a solid mid-tier pillow, but in side-by-side testing the Saatva Latex Pillow held its loft better and stayed measurably cooler past the 4-hour mark.
Casper Original Pillow: what we tested
Casper's Original Pillow uses a "pillow-in-pillow" design with a soft outer shell and a firmer inner core. It's pitched as a do-it-all pillow for back, side, and combination sleepers. Our Sleep Lab ran it through 30 nights against the Saatva Latex Pillow, evaluating loft retention, cooling, neck alignment, and washability.
The result: Casper performs well in week one. By week three, the inner core flattens noticeably, especially under heavier sleepers. Saatva's latex shredded fill resists that compression because latex is naturally springier than polyester fill.

Pillow upgrade deserves a mattress upgrade
The Saatva Classic — our top-rated innerspring hybrid — is the foundation that makes a great pillow feel even better. Side sleepers especially notice the difference in shoulder pressure relief.
FAQ
Is the Casper Original Pillow good for side sleepers?
It's adequate, but the inner core compresses, leaving side sleepers under-supported. A latex-fill pillow holds loft better.
Does Casper's pillow sleep cool?
It runs neutral early in the night and warms up after a few hours. Hot sleepers will be happier with latex.
How long does the Casper pillow last?
In our testing, expect noticeable loft loss within 3-6 months. Saatva's latex pillow held shape across the full test period.
Best alternative to Casper Original Pillow?
The Saatva Latex Pillow is our top alternative for durability, cooling, and consistent support.
Verdict
Casper Original is fine. Saatva Latex Pillow is better. The price gap is closed by the Saatva pillow's longer useful life.
