Ruoysun King Size Mattress, 12 Inch Medium Firm Hybrid King Mattress in a Box, Strong Edge Support, Motion Isolation, with 7-Zones Pocket Springs, Fiberglass-Free, Pressure Relief, CertiPUR-US

Features

• Precision-engineered for spinal alignment: Our 7-zone pocket springs are designed to follow your body's natural curve shoulders gently cushion, the lower back receives targeted support, and legs rest in complete relaxation. A plush memory foam layer sits on top, adding just enough softness. The result is a medium-firm feel that works very well for back, side, and stomach sleepers.
• Effective motion isolation for restful sleep: With over 400 individually encased pocket springs, movement is largely isolated at its source. When sharing your king bed with a partner, a child, or a pet, you'll notice very little motion transfer minimal shaking, very low noise, and barely any vibration. Even light sleepers can enjoy deeper, more uninterrupted rest.
• Cooling comfort that lasts all night: Heat buildup doesn't have to ruin your sleep. Our 7-layer construction includes a cooling-gel memory foam layer and ventilated comfort foams that actively pull heat and moisture away from your body. Combined with a breathable, soft knit cover, you'll remain cool, dry, and comfortable through the night helping you avoid waking up hot and sweaty.
• Reinforced edge support you can rely on: We've reinforced the entire perimeter of this king mattress with three full rows of high-density springs that's 30% more structural support than standard designs. Sit on the edge to put on socks, lie near the side, or lounge comfortably anywhere. The surface stays firm and supportive from edge to edge, night after night.
• Easy setup: Each Ruoysun king mattress is compressed and rolled into a compact box that fits easily through doorways and up stairs. Simply unbox, unroll, and let it expand (allow 4872 hours to reach full shape). Built in our own factory with multi-stage quality inspections, CertiPUR-US certified materials, and fiberglass-free construction. Backed by a 365-night trial and a 10-year warranty.
