A portable and adjustable device such as a chair is provided with upper and lower body-enveloping members for wind protection and control of exposure to solar radiation. A foot support is provided for sustaining the weight of the feet and legs. The device is preferably in the form of a rocking-chair or the like with retaining means to hold it at a desired angle of tilt, and may have a safety stop to prevent the user from tilting too far back and falling. An indicator may also be provided, to assist in determining the optimum azimuthal orientation and degree of tilt for maximizing the effective reception of solar radiation.
