About this product:
[Perfect Balance of Support and Comfort] Combines a base of independent pocket coils with a top layer of high-density memory foam. With a moderate firmness (medium-firm) that suits Japanese preferences, it prevents excessive sinking and achieves ideal responsiveness and a snug fit. Experience a luxurious sleep with this hybrid mattress.
[9-Zone Pressure Distribution - Supports Ideal Sleeping Posture] Features a plush quilted layer designed for those suffering from lower back pain. The advanced 9-Zone Independent Pocket Coil System provides precise support for each part of the body, from head to toe, maintaining the natural alignment of the spine. It gently conforms to body contours, instantly responds, disperses pressure, and leads to deep sleep that relieves fatigue.
[High-Resilience Urethane Supports Smooth Turning] The surface is made of high-density, high-resilience urethane with moderate elasticity. It prevents the body from sinking too deeply and smoothly supports natural turning during sleep. This reduces the need for extra muscle effort, improving sleep quality and allowing for thorough recovery from daily fatigue. We guarantee a hygienic, healthy, and refreshing sleep environment with CertiPUR-US certified safe urethane.
[Reinforced Edge Support Prevents Deformation] Three rows of thick, sturdy reinforced coils are placed around the perimeter of the mattress. This prevents the edges from sinking, maximizing the usable sleeping space. Whether sitting on the edge of the bed to put on shoes or turning over near the edge, you won't feel like you're sliding off, providing solid stability and peace of mind.
