Based on the provided white-background product images, generate a detailed poster for the supportive mattress. The background features a soft gradient from white to light sky blue. On the top left, a thick black sans-serif line reads "Fits the Body / Comfortable Support," while the upper right uses three lines of dark gray to indicate "Follow the natural curves / Relax to sleep / Stable companionship." In the center, a horizontal composition places a white quilted mattress with light blue sides, and an adult woman in light-colored loungewear lying on her side, her posture natural and quiet. A thin black continuous curve is drawn above the figure, accompanied by four black dots and labels for "legs," "waist," "shoulders and neck," and "head," showing the support relationships in different positions. At the bottom, two minimalist line-drawing sleeping position modules are arranged side by side: the left is supine sleeping, titled "Flat Support"; The right side is the side sleeper, titled "Following the Curve," each with a short description. The product maintains a white quilted top layer, light blue sides, and low cuboid proportions, allowing adjustment of quilting and figure pose. No brand information, no new brands or slogans, and avoid medical treatment statements, original images like "zero pressure," absolute promises, watermarks, and excessive small print.
