Casper Sleep Hybrid Twin XL Mattress - Medium Firm Memory Foam with Cooling and Support - 100-Night Trial - 10 Year Warranty

Reimagining sleep, Casper develops all its sleep products in-house with an award-winning research and development team. The Casper Original Hybrid mattress features three layers of premium foam for all-night comfort, along with innovative support from springs for added lift and airflow. Zoned SupportTM aligns the spine with softer support under the shoulders and firmer support around the hips, waist, and lower back. The top layer of AirScapeTM perforated breathable foam increases airflow to keep you cool at night, while the plush yet resilient premium foam conforms to your body to relieve pressure. Resilient springs add lift, support, and airflow, with a firmer border for edge support to help getting in and out of bed easier. The cover, made with recycled materials, easily zips off and is designed to withstand years of use. The knit mattress covers have four-way stretch for the full benefits of the layers underneath.

All our polyurethane foams are CertiPUR-US® certified, made without ozone-depleting chemicals and regulated phthalates, with low VOC emissions tested for indoor air quality. For troubleshooting, follow these steps: ensure the device is plugged into a working outlet, remove the plastic wrap on the PECO-Filter, turn the lid clockwise until it clicks into place, place the device on a flat surface, try placing the device on the floor in between your feet while turning the lid. If the device still won't power on, unplug it, place your finger on the center button on the lid, plug the device back in, continue holding the button for 5 seconds. Set up is simple: take the mattress out of the box and watch it decompress. Jumping, walking, and sleeping on the mattress can speed up the process.
