DANNASI 14 Inch King Hybrid Mattress, Medium Firm Pocket Coils

• Independent Pocket Coils & Effective Motion Isolation: This 14 inch king size hybrid mattress adopts individually wrapped pocket coil construction for independent and responsive support. Each tempered spring operates separately to reduce pressure interference and minimize motion transfer caused by nighttime tossing and turning. Designed with a balanced medium firm feel, it aligns with natural spinal curvature to deliver even full-body support, suitable for various body types and all regular sleeping positions.
• Fiberglass-Free Construction & CertiPUR-US Certified Foam: Built with an upgraded fiberglass-free internal structure, this king hybrid mattress eliminates hidden glass fiber layers to prevent skin irritation and potential indoor safety hazards. All inner foam layers are CertiPUR-US certified, free of excessive formaldehyde, heavy metals and restricted phthalates. The low-VOC and faint odor composition creates a clean, healthy sleeping space for long-term family use.
• High-Density Breathable Fabric For Stable Cooling Sleep: Wrapped with premium high-density breathable surface textile, this king size mattress enhances internal air circulation and efficient overall heat dissipation. The optimized internal airflow system releases trapped body heat in real time to prevent nighttime overheating and stuffiness. The soft skin-friendly cover maintains stable cooling performance, delivering cozy rest throughout all seasons.
• Balanced Medium Firm Feel For Full-Body Pressure Relief: Constructed with resilient pocket coils and adaptive comfort foam layers, this 14-inch medium firm king mattress delivers well-balanced sturdy support and gentle surface comfort. It evenly distributes body weight across the head, shoulders, waist and hip areas to relieve daily physical fatigue and muscle strain. The moderate firmness works perfectly for side, back and stomach sleepers to obtain consistent nightly comfort.
• Stable Hybrid Build & Standard King Size Dimension: Featuring standard king size dimension (80"L×76"W×14"H), this hybrid mattress is universally compatible with most king bed frames, platform beds, box springs and adjustable bases. The reinforced pocket coil frame matched with high-density resilient foam enhances overall structural stability, effectively resisting sagging and permanent deformation to extend the mattress’s service life for master bedroom daily use.
