Abstract

PURPOSE:To prevent local sinking, without heightening the density of arrangement of compressed springs, by providing a high rigidity for a coupling member which is used for the cushion of a bed or the like and connects the compressed springs to each other. CONSTITUTION:A coupling member 7 is made of band steel as well as compressed springs 4 so that one twisted part 7a of the coupling member has a twist angle of about 90 deg. to the other twisted part 7b. Since the load upon the coupling member 7 is distributed to the whole coupling member and carried by the compressed springs 4 through the horizontal parts 7a which are easily deformed, the spring assembly does not undergo local large elastic deformation under the load and no compressed springs need to be provided in positions corresponding to the twisted parts 7b of high rigidity. Therefore, the density of arrangement of the compressed springs 4 is lowered.
