About This Product

Our 12"" medium-firm hybrid mattress targets sleepers with back discomfort, delivering ergonomic spinal alignment and all-night pressure relief for restful sleep. Constructed with 8 layers of premium materials, it features breathable ice silk cooling cover paired with supportive high resilience foam and individually wrapped pocket coils to minimize partner motion transfer, alongside reinforced edge construction to effectively prevent long-term edge sagging. Vacuum compressed in a box for easy doorstep delivery; full expansion takes 48–72 hours (allow extra expansion time under 59°F/15°C). Box spring sold separately. Tips: A matching fitted sheet is recommended for extra warmth during cold winters; fitted sheets are sold separately and available for individual purchase.

Features

Zero-Odor Hypoallergenic Design: Sterile sealed production eliminates new-mattress chemical odors; no air-out time required right after unboxing, hypoallergenic construction fits sensitive skin & allergy sufferers.
Ice Silk Cooling & Breathable Surface: Cool-touch ice silk cover boosts internal airflow, avoids night sweats for year-round comfortable sleep.
Medium-Firm Ergonomic Spinal Support: Balanced medium-firm feel stabilizes spinal alignment, eases chronic back pain for back & side sleepers.
Pocket Coil Motion Isolation: Individually encased pocket springs + gel foam absorb tossing/turning, zero partner sleep disruption.
Reinforced Edge Support: Thickened perimeter structure improves sitting stability and long-term anti-sagging performance.
Convenient Boxed Delivery: Vacuum-compressed packaging for easy shipping & in-home setup with quick room placement.
