Experience all-night comfort and support with the Casper Original Hybrid Mattress. Featuring a two-layer foam system combined with resilient springs, this premium hybrid mattress provides pressure-relieving support for side, back, and stomach sleepers. Zoned Support delivers targeted ergonomic alignment: soft foam under the shoulders eases pressure, while firmer foam under the hips, waist, and lower back keeps your spine properly aligned. Breathable open-cell foam and hybrid construction promote airflow to keep you comfortably cool throughout the night. Medium-feel foam conforms to your body to relieve pressure points, while encased springs absorb motion transfer and provide edge support, making it easier to get in and out of bed. The stretchy knit cover enhances comfort by letting you fully experience the supportive layers beneath. All foams are CertiPUR-US certified, made without ozone-depleting chemicals, and meet strict indoor air quality standards. Ideal for couples, hot sleepers, and anyone seeking premium, all-night comfort and alignment.
