A knee cushion is adapted to be sandwiched between a user's knees. The cushion has a central region in which the user's knees can reside to prevent the cushion from being easily dislodged when the user is lying on his or her side. The central region of the cushion is completely surrounded by a peripheral region, and at least part of the peripheral region is raised with respect to the central region such that the central region forms a central-depression completely surrounded by the raised parts of the peripheral region. Another aspect of the invention relates to a different knee cushion which has one or two knee-fitting open channels each adapted to allow a user's knee to fit therein. The knee-fitting channel is limited in dimension such that generally only the portion of the user's leg at the knee resides in the channel.
