  • Enhance Your Sleep: This king mattress offers a medium-firm plus feel, and is stable and supportive without being too hard. This king size mattress strikes the perfect balance between comfort and structure, helping your body fully relax the moment you lie down on it. Wake up refreshed after a full night of undisturbed, restful sleep.
  • Scientifically Engineered Foam Layer Structure: The king cooling gel mattress features a scientifically engineered 6-layer design—with a graphene-infused cover for cooling, cooling gel memory foam pressure relief and odor control, and high-density base foam that contours to your body’s curves, prevents sagging, and provides lasting support—delivering balanced comfort and proper spinal alignment for all sleep positions.
  • Graphene Fabric for Cool Sleep: The outer cover of this king mattress is made of innovative graphene fabric, known for its excellent thermal conductivity. It efficiently disperses body heat across the surface of this king size mattress, reducing hot spots and creating a cooler, more consistent sleep environment throughout the night.
  • Certified Quality and Safety: The memory foam king size mattress is certified by CertiPUR-US, ensuring it’s free from harmful substances. The inner cover of this king bed mattress is also fiberglass-free, making it safe, skin-friendly, and non-irritating. Every layer is tested to deliver peace of mind and lasting comfort.
  • Easy Setup & Warranty: This vacuum-compressed king mattress (76" x 80") is easy to transport and expands to full size within 24–72 hours. Solo setup is simple and safe with the included free safety cutter. It comes with a one-year warranty but no trial period. If damaged during shipping, please contact customer service.
