The present invention relates to a supporting module (100) for use in an adaptive sleep system and to a sleep system comprising such supporting modules, the resistance (resilience) of which can be adapted in a simple manner to the anatomy and/or posture of a user. The supporting module (100) for an adaptive sleep system comprises an uppermost supporting element (110), at least two drive shafts (140, 140), at least two leaf springs (130, 130) positioned parallel to one another, each leaf spring (130, 130) including a first and a second end, each first end being connected to the first supporting element, and each second end being in contact with an adjacent drive shaft (140, 140) via a coupling element (150), wherein the position of the second end of a leaf spring (130, 130) with respect to the adjacent drive shaft (140, 140) determines the deformation resistance of this leaf spring (130, 130), and wherein the coupling element (150) has been configured to transmit the rotational motion of at least one drive shaft (140, 140) to the leaf spring (130, 130), in order to modify the position of the second end of the leaf spring (130, 130) with respect to the adjacent drive shaft (140, 140).

A system for evaluating failure of a used mattress includes a test device and computerized test device control module. The test device includes a plunger arm, a control motor attached to a first end of the plunger arm and configured to selectively extend and retract the plunger arm, and a platen attached to an end of the plunger arm distal from control motor. The control module includes a computerized processor, operating programming to evaluate the failure of the mattress. The programming includes controlling extension of the plunger arm, monitoring firmness in the mattress based upon force applied by the platen on the mattress and displacement of the plunger arm, monitoring a threshold firmness value for comparison, comparing the threshold firmness value to the monitored firmness, and generating a result of the comparison indicating the failure of the mattress.

A pocket-spring core having at least one first zone and at least one second zone, wherein the first zone has at least two rows of a first spring portion and at least one of the second zones has at least one row or line of a second spring portion, wherein the second spring portion has at least two layers which are located vertically one above the other and comprise in each case a plurality of helically wound first compression springs, in a first, upper layer, and second compression springs, in a second, lower layer, and at least one row of a third spring portion, is distinguished in that at least one of the second zones of the pocket-spring core has at least one channel-like depression.

A mattress assembly includes a chassis having top and bottom walls and first and second sidewalls that each extend from the top wall to the bottom wall. Inner surfaces of the walls and the sidewalls define an interior cavity. The top and bottom walls each include a first section that is connected to the first sidewall and a second section that is connected to the second sidewall such that the first sections are pivotable relative to the first sidewall and the second sections are pivotable relative to the second sidewall. The first section of the top wall is pivotable relative to the second section of the top wall and the first section of the bottom wall is pivotable relative to the second section of the bottom wall. A spring assembly is configured to be positioned within the interior cavity.

A posturized comfort layer for a bedding or seating product has different sections of different firmness due to different mini coil springs within the sections. The springs may be individually pocketed between two sheets of non-woven polypropylene fabric joined with circular seams or rectangular seams. Each circular seam joins opposed pieces of fabric around one of the mini coil springs with curved segments. Alternatively, rectangular seams join opposed pieces of fabric around each of the mini coil springs with linear segments. Regardless of the shape of the seams, the different firmness of the different sections of the comfort layer may be due to the mini-coil springs contained in the pockets.

A pocketed spring assembly comprises a plurality of parallel strings of springs, each string joined to at least one adjacent string, each string comprising one piece of fabric folded into first and second opposed plies of fabric. Outer pockets are formed along each string by transverse seams joining the first and second plies. One pocketed spring and at least cushion pad is positioned in each outer pocket. The cushion pad may be individually pocketed. An upper end of each transverse seam may be below an upper surface of the string to partially separate adjacent outer pockets within a string.

Methods and systems for no-glue pocketed spring unit construction. Rows of pocketed springs, preferably arranged into modules of more than two pocketed springs surrounding a central hole, are ultrasonically welded together when paired vibrating probes and anvils press layers of pocketed spring fabric from the rows of pocketed springs together and a welding pulse is transmitted to the vibrating probe.

A pocketed spring assembly comprises first and second sheets of fabric and a plurality of parallel rows of springs held in place with the sheets. Longitudinal seams joining the first and second sheets extend generally the same direction as the rows of springs. Pockets are formed along a strand of springs by aligned separating seams. At least one spring is positioned in each pocket. Each separating seam joins one of the sheets to itself and keeps the spring in its pocket. Ends of aligned separating seams are spaced from each other, thereby improving airflow between pockets. Openings between adjacent longitudinal seams further improve airflow.

A bed mesh combination device includes a first loading mechanism, a feeding mechanism, a second loading mechanism, and a combination mechanism. In a first direction, the first feeding mechanism transports the first spring strings of a set length to a first position, and the feeding mechanism transfers the first spring strings from the first position to a second position. At the second position, the first spring strings are parallel to the first direction. The second loading mechanism can reciprocate in the first direction, so as to continuously arrange the second spring string back and forth in the first direction at the second position. At the second position, there is one first spring string between two adjacent sections of the second spring string. The combination mechanism welds or sews the first spring strings at the second position and the adjacent second spring string to form a bed mesh.
