The Gravity Ice Hybrid Mattress focuses on the cooled environment and unmatched support of the body for an outstanding sleep. The combination of coils and foam prevents the mattress from dipping, so the hips and key spinal points are more supportive and in its correct shape. Moreover, the hybrid design of the coil-foam maintains the mattress shape over time for long-lasting endurance. The cooling gel layer allows the airflow from the coils to ensure a more comfortable slumber throughout the night. What is excellent about Gravity Ice Hybrid Mattress is you'll get a 100 nights of addicted sleep if you decide to return before you can.
