Casper is reimagining sleep from the ground up. All of Casper’s sleep products are developed in-house by our award-winning research and development team. The Casper Original Foam mattress is the perfect combination of support and cooling. Our ZonedSupportTM has three areas of targeted support for proper spinal alignment. Soft foam around the shoulders provide more relief to the upper body. Firmer foam under the hips, waist, and lower back help align your spine. Breathable open-cell foam layers allow airflow to soothe you to sleep. This premium foam is plush, yet resilient and conforms to your body to relieve pressure. The durable base foam prevents sinking and sagging and supports the whole body. It’s designed to withstand years of use. The knit mattress covers have four way stretch, so you feel the full benefits of the below layers. Still unsure? Rest easy with our 100-night trial and free returns.
Our innovative mattress formula that brings together a proprietary combination of materials to unlock your best night’s sleep—for even better tomorrows.
Softer foam around the shoulders provides more relief to the upper body. Firmer foam under the hips, waist and lower back helps align your spine. Breathable open-cell foam layers allow airflow to soothe you to sleep.
All of our polyurethane foams are CertiPUR-US certified.
They are made without ozone-depleting chemicals and phthalates regulated by the Consumer Product Safety Commission, and are tested for low VOC emissions for indoor air quality.
Please allow 24-72 hours for your mattress to regain its full shape. Any memory foam will expand faster in a warmer room. In cold temperatures your mattress may take a bit longer to return to its full size.
Customers say
Customers give positive feedback about the mattress’s quality and sleep benefits, particularly noting it’s best for side sleepers and helps eliminate the need for pain medication. The comfort level receives mixed reviews, with some finding it too soft while others report no back pain. Durability, firmness, support, and value for money are also mixed aspects – while some find it well-made and supportive, others report issues with sagging edges and lack of support, and some consider it overpriced.
