It is a reflective sheet that clips onto almost any chair (especially good with folding chairs) and, curved down behind and partly under the chair, reflects the radiant energy from the fire toward your bottom and back.
Made of a durable reflective laminate material for long life. Great for campers and cottagers. Also good in front of wood stoves or heaters in ice fishing huts. Measures 22" x 45".
Made in Canada.
