- Better sleep: Ergonomically shaped leg pillow designed to sit between the knees or legs, adapting to their shape for a soft, comfortable feel. The hollow center promotes air circulation for a cooler experience and improved sleep quality. - Elastic band design: Elastic strap prevents slipping when adjusting position, so there is no fumbling in the dark. Gently cradles the thighs in a horizontal, natural position and helps keep hips, legs and knees aligned during sleep. - Premium memory foam + washable pillowcase: The pillow is vacuum packed and should stand for 1 hour before use to regain shape. Memory foam quickly returns to shape. The memory foam core cannot be washed; remove it through the zipper and wash the pillow cover by hand or machine. - Pain relief: Memory foam with a special shape to fit perfectly between the legs, relieving pain for sciatica, back, buttocks, knees and joints, and supporting comfort during pregnancy.
