【Ergonomic Design】 The orthopedic pillow is ergonomically designed to support all sleeping positions. The pillow comfortably hugs your head and neck, adapting to the natural curves of your head and neck, supporting your head, neck, shoulders, and back in a neutral position for a stable sleeping position and a good night's sleep. 【Armrest Design】 This neck pillow has grooved armrests on the sides of both corners. When lying on your back, you can place your hands in the grooves to make it easier to fall asleep. No matter which way you turn, your arms can rest comfortably in the indentations. The arms wrap forward around two corners for perfect support and comfortable stomach sleeping. 【Breathable and Easy to Care For】 The memory foam pillow core is wrapped in inner and outer pillowcases. The outer pillowcase is removable and washable, skin-friendly, and soft to the touch. The inner pillowcase is breathable, quick-drying, and dustproof. It protects the pillowcase from bacterial contamination and further improves cleanliness, as fresh and breathable as breathing. 【Hassle-Free Shopping】 takes product quality very seriously and is committed to providing customers with quality products and 100% satisfaction.
