Description The Piano Air pillow by Kanuda provides cervical and shoulder support with a slightly firmer but supported feel. As our most versatile choice for rounded back-of-head shapes, its lower occipital contour and steeper back-to-neck transition promote C-curve realignment without over-elevating the head. The cradling profile helps minimize tossing and turning.

The neckline should be adequately adjusted to the upper cervical area of the upper neck and the border of the back of the head. Both sides are the parts used to sleep to the side. Put your head to the side of the pillow; this makes your head and neck horizontal. When lying down sideways using Kanuda pillow, your head and neck will be horizontal with the spine and minimize pressure to your shoulder, giving less pressure to your spine and will aid in sleeping. Care Instruction When washing the product, wash the cover only. Do not wash the inner memory foam. The waterproof inner lining protects the foam from sweat, moisture, and/or sweat, so the foam does not need to be washed. When using a washing machine to wash the cover, please use a washing net, and by hand wash, wash gently. Use the pillow in a flat, safe place. A high-temperature mattress pad may change the shape of the pillow. Do not manually minimize or change its shape.
