Product Description Ergonomic design. The heart-shaped design with high sides and a low center is designed to fit the curves of your legs and knees, ensuring your back and buttocks are in a natural state when you sleep on your side. The hollow center increases breathability. The elastic band helps keep the pillow in place and allows you to sleep peacefully. High-quality material. The knee pillow is made of 100% premium memory foam, which effectively relieves pressure from your legs and has good resilience. After use, the pillow returns to its original shape.

Relaxing at night can improve your sleep quality and give you a fresh start the next day. Easy to clean - simple zipper, removable cover, durable, machine washable. There is no need to wash the inner core of the pillow. After 1-2 months of use, simply place it in a cool, ventilated place for 2-3 hours. Perfect gift.
