A lower extremity exerciser and positioning device includes a generally wedge-shaped inferior and a generally wedge-shaped superior support. Each support has a top surface and curved trailing edge. A limb-cradling furrow extends across the top surfaces and trailing edges. The inferior support may be used alone, or with the superior support stacked on top. Spacers may be added to extend and elevate the device. Releasable attachments are provided to secure together adjacent components. The device may be configured to accommodate various patient physiques; used to relieve heel, sacral and buttock pressure for purposes of avoiding pressure ulcers; and used to allow patients to independently perform various knee and hip exercises.
