DANNASI 14 Inch King Hybrid Mattress, Medium Firm Pocket Coils Gel Foam

• INDEPENDENT POCKET COIL DESIGN WITH EFFECTIVE MOTION ISOLATION: This 14 inch king hybrid mattress adopts individually wrapped pocket springs for independent elastic response. Separate operation of each coil cuts down cross-spring pressure transfer and efficiently blocks movement disturbance from nighttime tossing and turning. The medium-firm supportive surface conforms to natural spinal alignment, delivering balanced full-body support to fit side sleepers, back sleepers and stomach sleepers with different body builds and sleeping postures for uninterrupted rest all night long.
• FIBERGLASS-FREE STRUCTURE WITH CERTIPUR-US CERTIFIED SAFE FOAM: Constructed with a fully upgraded fiberglass-free internal framework without hidden fiberglass layers, this black hybrid mattress prevents skin discomfort and unnecessary safety risks. All interior comfort foam layers pass official CertiPUR-US testing, tested free of heavy metals, excessive formaldehyde and restricted phthalate contents. Low-VOC and mild low-odor foam composition creates a steady clean sleeping environment suitable for daily long-term use for the whole family.
• HIGH-DENSITY BREATHABLE FABRIC FOR ALL-SEASON COOL SLEEP PERFORMANCE: Wrapped with high-quality skin-friendly knitted surface fabric optimized for high air permeability, this king size mattress accelerates internal air circulation and fast body heat dissipation. Optimized inner airflow design locks in consistent cooling performance to stop overheating and stuffiness during overnight rest. The smooth soft textile maintains stable comfort in hot summer and cool winter, realizing reliable all-night temperature regulation for year-round rest.
• WELL-BALANCED MEDIUM FIRM SUPPORT FOR FULL-BODY PRESSURE RELIEF: Built with matched resilient pocket springs and adaptive comfort foam layers, this medium firm hybrid mattress balances supportive firmness and cozy softness well. It distributes body weight evenly across head, shoulder, waist and leg areas to release accumulated physical pressure and ease daily body fatigue. The versatile firmness level works well for most sleepers, offering stable comfortable rest every night.
• STANDARD KING SIZE & VACUUM COMPRESSED HYBRID MATTRESS IN A BOX: Featured with standard king size dimensions of 80”L x 76”W x 14”H, this mattress fits most king bed frames, platform beds, adjustable bed bases and box springs seamlessly. Reinforced hybrid coil and high-resilience foam construction enhances overall structural stability and wear resistance, effectively resisting long-term sagging and deformation to extend service life. Vacuum compressed rolled packaging simplifies transport and space-saving storage, ideal for master bedrooms, family apartments and guest rooms for daily long-term sleeping needs.
