◆【8 Ways to Customize Your Sleep Comfort】 2-layer structure with 80N low-resilience x 260N high-resilience & tri-fold design. Freely rearrange the firmness for your head, waist, and legs. Find your ideal sleep comfort with this hybrid mattress. Perfect for those unsure about firmness, those who toss and turn a lot, or families with different preferences. Reduces the risk of too hard or too soft mistakes.
◆Features a 2-layer hybrid structure with 4cm of 40D density low-resilience urethane on the top layer and 6cm of 34D density high-resilience urethane on the bottom layer. Gently cradles you while providing firm support, preventing excessive sinking. Recommended for those suffering from back pain or stiff shoulders, and for side or back sleepers. The 10cm thickness provides ample cushioning, whether used on a bed or directly on the floor.
◆Luxuriously uses high-purity, high-density urethane (top layer 40D / bottom layer 34D) for high durability that resists sagging even with long-term use. The 6-part replacement unique to the 2-layer x tri-fold design disperses pressure on the waist, reducing the frequency of replacements and saving money. It continues to provide firm support even with daily use and is recommended for family use.
◆Bamboo charcoal infused x washable reversible cover. The main body is infused with bamboo charcoal for deodorizing, antibacterial, and moisture-regulating functions, keeping it clean. The cover is reversible with a knit side (soft) and a mesh side (smooth and breathable) for year-round comfort. Machine washable, always hygienic. Lightweight and folds compactly for storage, easy to air dry, making it easy to handle for women and the elderly.
