A seat assembly and method of assembly. The seat assembly comprises a frame, a cushion, and a fastening arrangement. The cushion is disposed on the frame and comprises a mesh member comprising a set of filaments of polymeric material. The fastening arrangement extends through the aperture in the frame and secures the cushion to the frame.

A strand-based tensioning structure for inflatable products has improved strength and durability. The tensioning structure includes fine-diameter, high-strength multifilament threads adapted to reconfigure into a flattened and/or spread out within the weld strip(s) to which the strands are attached. This flattening, combined with the fine diameter of the strands welded material, allows the threads to become thoroughly integrated within the weld strip material after welding, promoting a high-strength interface between the weld strip and the threads. Additionally, the material of the weld strip itself is left substantially intact to promote a high-strength interface between the weld strip and the outer sheets to which the tensioning structure is fixed. An adhesive may also be integrated into the multifilament threads to further strengthen the weld strip/thread fixation upon welding.

Cushions, methods, and manufacturing systems for making the same are disclosed. The cushions may be foamless such as being made from a body of entangled and/or intertwined polymeric strands. The manufacturing systems may include a die such as die bars having a plurality of orifices that cooperate with a plurality of receptacles and actuators for discharging a plurality of fasteners from the receptacles, through the die into the cushions. In a refinement, the die may be heated such that a skinned over membrane is created in the cushion to retain the plurality of fasteners. A trim cover may cooperate with the plurality of fasteners such that it is attached to the cushion.

Support element for a chair, which comprises a support body provided with an upper face and with an opposite lower face, and a covering element placed to cover the upper face of the support body. The support element also comprises a tensioning element engaged with a perimeter portion of the covering element and provided with a grip portion, which is susceptible of being stretched in order to tighten the covering element and is constrained to the support body in order to maintain the covering element taut on the support body. The support element also comprises a guide element which is fixed to the lower face of the support body, and a traction element which is mechanically connected to the grip portion of the tensioning element and is slidably engaged in the guide element, in order to tighten the covering element among multiple tensioning positions.

In order to manufacture an innerspring unit comprising pocketed springs and having an increased stability at its edge regions, in a first step, an innerspring main body comprising a plurality of first strings of pocketed springs is provided. In a subsequent second step, at least one second string of pocketed springs is attached to a lateral surface of the innerspring main body, so that the at least one second string of pocketed springs extends in a longitudinal direction of the innerspring main body. The springs of the at least one second string of pocketed springs have a spring characteristic or a spring geometry different from the springs of the plurality of first strings of the innerspring main body. The at least one second string of pocketed springs forms together with the innerspring main body the innerspring unit.
