DANNASI 12 Inch Queen Hybrid Mattress, Medium Firm 7-Zone Gel Memory Foam

• [7-Zone Pocket Coil Support] This mattress features 7-zoned individually encased pocket coils to deliver ergonomic targeted support for the head, shoulders, waist, hips and legs. It evenly distributes body weight to reduce excessive sinking and relieve spinal compression, suitable for side sleepers, back sleepers and stomach sleepers across various body types. Independent wrapped coil construction brings reliable motion isolation, so your partner’s nighttime movements will not interrupt your rest. Standard Queen size dimension: 80 x 60 inches, 12 inches thick.
• [Cooling Gel Memory Foam] A top layer of cooling gel-infused memory foam effectively dissipates trapped body heat to minimize nighttime overheating for steady refreshing sleep. The plush foam cushions pressure points around shoulders and hips without deep sinkage, pairing perfectly with pocket coils to achieve a balanced combination of soft cushioning and supportive firmness, avoiding overly stiff or overly soft sleeping surfaces. The 12-inch multi-layer structure delivers full-body padding and consistent support for all-night comfort.
• [Medium-Firm Comfort Level] Constructed with a well-balanced medium-firm comfort level that fits the daily sleeping habits of most users. It holds your body posture steadily to prevent excessive sagging or rigid hardness. This Queen mattress is compatible with common bed frames, including platform beds, slat bases and box springs, delivering stable and consistent comfort night after night.
• [CertiPUR-US Safe & Healthy Materials] All internal foam layers meet official CertiPUR-US standards, manufactured without formaldehyde, restricted phthalates and heavy metals. Low-VOC and low-odor foam creates a fresh sleeping space free of strong chemical smells. The fiberglass-free build lowers the risk of skin discomfort, ideal for family use, kids and people with sensitive skin.
• [Compressed Mattress in a Box] Vacuum compressed and sealed in a compact carton for easy doorstep delivery, light enough for one person to carry upstairs conveniently. Simply unbox and unroll the mattress, and allow 24–72 hours for full expansion to its original shape. Reinforced edge perimeter structure prevents sliding and edge sagging when sitting or resting along the sides, ensuring long-lasting stable performance.
• [Long Durability & Low Maintenance] High-quality steel pocket coils maintain solid structural stability during long-term daily use. Breathable surface fabric enhances internal air circulation and slows exterior dust accumulation. Minor surface stains can be gently cleaned with a damp cloth without complex maintenance procedures. The sturdy construction maintains consistent supportive performance for long-time use.
