The Casper Original Hybrid Medium Mattress is designed to provide an ideal balance of comfort and support for a wide variety of sleep styles. Combining premium foam layers with Flex Coil Supportive Pocketed Springs, it delivers responsive comfort without feeling too soft or too firm. The breathable QuickCool™ Cooling Mattress Cover works together with AirScape® Cooling Foam and Phase Change Material to promote airflow and help disperse excess body heat for cooler, more comfortable sleep. At the center of the mattress, Zoned Support™ Pressure-Relieving Memory Foam incorporates three ergonomic support zones that help maintain healthy spinal alignment while providing targeted cushioning where it's needed most. Flex Coil Supportive Pocketed Springs respond independently to movement to provide adaptive support while reducing partner disturbance. The balanced medium feel offers versatile comfort for side, back, and combination sleepers.
