This multi-use patented pillow is composed of two half-cylinders that in a closed position it can be used as a cylinder to provide support under the cervical area of the neck and behind the lumbar area, as well as, under or between the knees.  If you open it horizontally you have another cervical pillow. Opened one of the half-cylinders fits directly below the neck providing support to the cervical area while the head lies down on the other half-cylinder providing cushion.  Vertically opened could be used by belly sleepers.
For those who don’t use pillows at all, you can use the half-cylinder below the neck to get the support in the cervical area without the feeling of using a pillow.
It is made of high-quality memory foam and includes a breathable cover that can be removed for easy wash. The product has a pleasant touch and feel to its material.
Pillow size: closed 6"x 19'' and opened 3"x19.
