Adjustable Back Rest Structure

Abstract

An adjustable back rest structure is essentially composed of a soft mat and a plurality of leaning pads. The soft mat at least has a fastening surface, and each of the leaning pads is provided with a locator at the back surface thereof. The soft mat can be covered or laid on a seat, a chair or a bed or the like which is either for sitting or lying. The fastening surface of the soft mat is exposed to be fastened with the locators of the leaning pads thereby fastening the locators respectively at a proper position which matches nearly for individual user's backbone curve thereby enabling the user to sit down or lie down in an easy posture.
