12 inch King Mattress, Memory Foam & Spring Hybrid Medium Comfort King Size in a Box,Adult

Core Technology - Quadruple Spinal Protection System

✅【 870 hollow independent bagged spring matrices】

Partition dynamic support: 870 high-density hollow springs are scientifically arranged to accurately match the three major pressure points of the human shoulder, neck, lumbar spine, and legs, achieving 5-zone support (head/shoulder/waist hip/thigh/calf). The springs respond independently when turning over at night, reducing the risk of spinal distortion

Silent and anti-interference: The bag structure isolates the friction sound of the spring, combined with the technology of non interfering with each other during exercise, so that there is no vibration transmission when the partner wakes up at night, and the duration of deep sleep is increased by 30%

Edge reinforcement design: Memory plasticity material, with soft edges and first-class rebound performance.

✅【Gel memory cotton constant temperature pressure relief layer】

NASA homologous material: 5cm thick gel memory cotton, absorbing 90% human pressure ³, simulating zero gravity floating feeling, especially suitable for people with lumbar strainHoneycomb vent design: thousands of breathable micropores inside accelerate air circulation, paired with cool fiber fabric, reducing the perceived temperature by 2-3 ℃ at night, bidding farewell to stuffiness and night sweats

✅【3D Fabric System】

Three dimensional breathable mesh fabric: The surface layer is made of 3D honeycomb three-dimensional fabric, which has a 200% increase in breathability compared to traditional knitted fabric, forming a mattress "breathing system" and keeping it dry all night long

Sensitive skin friendly design: using built-in silver ion technology to help maintain fabric cleanliness and reduce factors that may cause discomfort. Specially designed for sensitive individuals, providing a more reassuring sleep experience

✅【No glass fiber safety structure】

Environmentally friendly material upgrade: Abandoning traditional glass fiber fireproof layer, using food grade flame-retardant knitted fabric to avoid fiber exposure and irritation to the skin or respiratory tract.
