Abstract: Disclosed is a pillow for placing between the knees while sleeping. The pillow has a substantially toroid-shaped outer casing with an inner volume containing a fill material. The generally uniform round shape of embodiments of the pillow provides for easy insertion of the pillow between the knees because the pillow does not have to be oriented in any particular radial direction prior to insertion. Some embodiments of the pillow may have a hole through the center. Both the top and bottom surfaces of embodiments of the pillow curve downward and inward toward the center, forming a top and bottom depression for cradling the knee joints while preventing the pillow from unintentionally sliding out from between the knees. A method of using a pillow for placing between the knees is also disclosed.
