The Casper pillow’s defining feature is its zoned construction: a firmer center for neck support flanked by softer edges for head cradling, all wrapped in a breathable, pillow-in-pillow design. This provides a balanced feel that can suit side sleepers seeking alignment, though its non-adjustable nature and tendency to soften over time are trade-offs for the premium price. It’s a reputable, well-executed option, but its fixed firmness won’t accommodate every preference.
