<p>A multi-functional stone double bed is provided to block earth radiation(or water current) and electromagnetic waves, to demonstrate anti-bacteria, deodorization and humidity control functions, and to allow separate temperature control by users. A stone bed comprises: a mattress composed of a hardwood powder non-woven fabric and a stone layer capable of radiating far-infrared rays; a resilient material(30) built inside a buffering part(27) underneath the mattress; and a plurality of suction valves(28) and exhaust valves(29) arranged at the outer peripheral face of the buffering part. The suction valve includes a suction port to which outside air flows in by the resilient force generated from the buffering part, an inlet, and a shield for preventing the air leakage. The exhaust valve includes a discharge port, a pressing plate adhered to the discharge port, an exhaust port for discharging inside air by an external pressure exceeding the resilient force of a spring, and a connection part for pressing the buffering part and the exhaust valve.</p> |
