<p>A support for backrest and waist mounted to a seat furniture, for example, chairs or legless chairs comprises spring bodies, respectively, provided on a first arm supporting a first elongated projection for pressing the back of a user and a second arm supporting a second elongated projection for pressing the waist of a user, the spring bodies providing bias for constantly pressing the back and waist of a user and making the arms swingable. Alternatively, the first and second arms themselves may be elastic bodies instead of providing the spring bodies. Further, an angle between the first and second arms may be adjustable. Accordingly, in no matter what manner a user sits, for example, slouching, the first and second projections can press the back and waist of a user, so that only sitting naturally enables a user to open the chest, extend the back and fully get relaxed, whereby a user can relieve fatigue of the body and relax.</p> |
