The invention relates to a flexible member with adjustable stiffness for lying and/or sitting furniture. This member includes one or more inner spring(s) oriented along a central axis, one or more pair(s) of outer helical springs about the central axis, and a rotating part able to rotate, about the central axis, between a blocking position and an unblocking position. Each pair of outer helical springs includes an upper outer helical spring and a lower outer helical spring, connected by a corresponding hinge, which has a pivot axis orthogonal to the central axis. In the blocking position, the rails engage the corresponding hinges of the pairs of the outer helical spring, so as to prevent radial displacement, relative to the central axis, of the corresponding hinges, while the unblocking position allows the radial displacement of each corresponding hinge.

The present invention relates to a thermoplastic spring, comprising a lower spring base portion (1) and an upper spring base portion (2), a female spring die (3) and a male spring die (4), wherein the female spring die (3) and the male spring die (4) are located between the lower spring base portion (1) and the upper spring base portion (2), wherein a pin is located on the male spring die (4) and a hole is located on the female spring die (3), wherein an installation process of the thermoplastic spring is performed by placing the placing the pin through the hole.

Spring modules for an adjustable sleeping system. At least some of the example embodiments are spring modules comprising: a spring rail, and a plurality of adjustable spring assemblies spaced along the length of the spring rail. Each adjustable spring assembly may comprise: a motor with a stator coupled to the spring rail, a lead screw coupled to the rotor of the motor, and the lead screw extending above an upper surface of the spring rail, a spring plate coupled to the lead screw, and a main spring coupled to the spring plate. Thus, the weight or force carried by each adjustable spring assembly along the spring rail is separately adjustable by a bed controller.

An arrangement of spring elements for a cushion support is provided, having a plurality of spring elements, at which between a base and a support disc spring arms are arranged in each case, wherein the spring elements are arranged lying next to one another in such a manner that the support discs of the plurality of spring elements jointly define a support area and connecting elements are interconnected via the spring elements in such a manner that the spring elements are fixed in their position relative to one another, wherein the connecting elements are formed in one piece and are integrally molded onto the spring elements. The application furthermore includes a stack of spring element arrangements.

A detachable portable spring bed has a bed frame, a spring group, a cushion; the bed frame is detachable, wherein when used, the bed frame is held up, the spring is detachably assembled to the bed frame, the cushion is lay on the springs, when in packing state, the springs are detached and overlapped, the bed frame is detached to components; the spring group, the components of the bed frame, the cushion are collectively packed or independently packed. The bed frame, the spring group, the cushion are detachable.

A mattress includes a top face, a bottom face, a pair of opposing sides defining a mattress width there between, a first microcoil support foam layer and a second microcoil support foam layer. The first microcoil support foam layer includes a plurality of first pockets and a plurality of first protrusions, and the second microcoil support foam layer includes a plurality of second pockets and a plurality of second protrusions. A plurality of separate microcoil cells are formed as lines of microcoils having a width of a single microcoil and a length containing sufficient number of microcoils such that the line of microcoils spans the mattress width. Each one of the microcoil cells is disposed between a given second protrusion and first pocket or a given first protrusion and second pocket.

A bedding or seating product comprises a pocketed spring assembly comprising a plurality of parallel strings of individually pocketed springs. The strings of springs may extend from head-to-foot or side-to-side of the product. Adjacent individually pocketed springs are separated from each other by at least one separating seam. Each of the separating seams comprises a pair of Y-shaped or U-shaped seams which may be joined together or spaced apart.

A bed for promoting growth and relaxing joints and muscles includes a bed mattress part and rotation roller parts on both sides of the mattress part to support a user's upper and lower body, which move the user's upper and lower body in the directions of the end of the head and the end of the toes with respect to a pelvis region to stretch the body, thereby promoting growth and relaxing the joints and muscles. The bed promotes growth, in infants, children and teenagers, by providing an artificial stimulus of stretching not only joints in which physeal plates are positioned, but also the whole body in a sleeping state; and in the case of adults whose growth period is complete, recovering joints which have been pressed due to activities such as standing or carrying heavy items, promoting blood circulation by stimulating the skin, and relaxing the muscles.
