An assembly of two sliding portions with respective folding legs comprises a supporting frame deployable on a bed or the like so that infrared radiation may be used from an ordinary electric blanket lifted-away from a sleeper's body, thus freeing the sleeper from body contact with any blanket; the assembly is lightweight and portable and can be set-up for use and folded for storage without any tools, gravitational force being used to hold the subassemblies together.
