Abstract: A leg rest for supporting a patient's legs while the patient is lying on a bed and during turning or otherwise managing the patient. The leg rest includes a pair of trough portions for receiving the patient's legs and a raised central portion and a pair of raised side portions for keeping the legs apart and restraining sideways leg movement. The central and side portions extend beyond the trough portions for restraining sideways movement of the patient's feet as the patient's legs rest on the trough portions with the patient's feet projecting beyond the trough portions for pressure relief of the patient's heels. The leg rest may be inflatable so that it may be inexpensively produced and disposable and so that its pressure may be adjusted for patient comfort. The leg rest may be contained within a case which has a bib for underlying the patient's upper legs to prevent slippage of the leg rest out of position.
