Product Description Ergonomic Design: The heart-shaped design with high sides and a low center is designed to fit the curve of your legs and knees, ensuring your back and buttocks are in a natural state when sleeping on your side. The hollow center increases air permeability. The elastic band helps keep the pillow in place, allowing you to sleep peacefully. High-Quality Material: The knee pillow is made of 100% premium memory foam, effectively relieving pressure from your legs and offering excellent resilience. After use, the pillow returns to its original shape. The pillow is made of polyester fiber, the same material used in yoga mats – it's soft, breathable, and elastic. Relaxing at night can improve your sleep quality and rejuvenate you for the next day. Easy to Clean: Simple zipper design, removable cover, durable, and machine washable. There's no need to wash the pillow's inner core. After using it for 1-2 months, simply place it in a cool, ventilated place for 2-3 hours.
