Memory Foam for Optimal Support: The car lumbar cushion contains high-quality memory foam that provides body support similar to a beach experience. Soft on the outside and firm on the inside, the foam perfectly conforms to the contours of your body, offering immediate relief and support for the lumbar spine while driving. Ergonomic Design for a Perfect Fit: With its fully curved ergonomic design, the cushion seamlessly adapts to the lumbar region. The curved surface of the cushion achieves a G3 shape, ensuring a perfect fit for the human waist, supporting the spine, and promoting a healthy sitting posture. Skin-Friendly and Soft to the Touch: The cover is made of skin-friendly, soft fabric that provides a pleasant sensory experience. The fabric is smooth and feels soft, enhancing comfort. The material is suitable for both the outer cover and the skin, ensuring a gentle body feel. Stable Lumbar Support: The cushion’s design supports the lumbar vertebrae while firmly clamping the sides of the lumbar region. When the micro-convex cushion surface is pressed, the lumbar support wings lift and gather inward, providing stable support and increasing comfort. Non-Slip and Breathable Back: The back of the cushion fits perfectly into the original car seat and does not slip. The breathable material ensures comfort in all seasons. It is made from soft and breathable Xinjiang cotton. The removable and washable cover, along with fine stitching and a dotted design, makes the cushion easy to maintain and durable.
