【Dual-Thickness Support & Durability】: Our 10-inch and 12-inch spring mattresses combine robust innerspring systems with reinforced layers for lasting support. The 10-inch design features dual-layer tempered coils for balanced firmness, while the 12-inch version adds a third support layer for enhanced durability, preventing sagging and maintaining spinal alignment. Both resist motion transfer and adapt to body contours. 【Luxurious Comfort Layers】: The 10-inch mattress includes 2.5 inches of cooling gel-infused memory foam and high-density cushioning for pressure relief. The 12-inch upgrade adds an extra 1.5-inch plush Euro-top layer, offering deeper contouring for hips and shoulders. Breathable fabrics in both ensure airflow to combat overheating. 【CertiPUR-US & OEKO-TEX Certified】: Materials in both thicknesses are rigorously tested for safety, free from harmful chemicals, heavy metals, and odors. The hypoallergenic construction supports healthier sleep, with eco-conscious foam layers that retain freshness over time. 【Reinforced Edge Support】: Both mattresses feature perimeter stabilization technology—thicker foam encasement in the 12-inch model—to prevent edge sagging and expand usable sleep space. Sit or sleep near the edges confidently without roll-off concerns. 【Hassle-Free Setup & Compatibility】: Compressed and shipped in a box, the 10-inch and 12-inch mattresses unbox effortlessly. Allow 24-72 hours for full expansion and odor dissipation. Compatible with most bed frames, including adjustable bases, they deliver instant comfort with zero assembly required.
