An upholstery member includes a base board (101) having at least one base board opening (116), a fixation arrangement (140), and a resilient wadding (102). The wadding (102) is pressed at least to some extent through the base board opening (116) and connected to the fixation arrangement (140), thereby forming an indent (130) in the upholstery member (100). Further, the invention relates to a method for manufacturing the upholstery member comprising the steps of providing (310) a base board (101) having at least one base board opening (116) and being covered with a wadding (102) on a front side of said base board (101), passing (320) the wadding (102) through said base board opening (116), whereby the indent (13) is formed, and securing (330) the position of the wadding (102) relative the base board (101).

The present invention relates to a multiple-pronged fastener. The fastener. such as a tack. has a geometrically-shaped or ornamental head, a plurality of prongs extending from the edges or periphery of the head, and one center prong extending from the center of the rear surface of the head. The multiple prongs secure the fastener in position safely while eliminating rotation of the tack along the central axis when applied to the item. The four prongs are preferably triangular, and the center prong is preferably square.

A seat includes a seat surface having a periphery and a carrier overmolded onto the seat surface over the periphery. The carrier has a periphery and a frame is overmolded onto the carrier over the carrier periphery. The seat is assembled without fasteners. A method for making the seat includes overmolding a carrier onto a periphery of a seat surface to form a seat surface/carrier assembly, tensioning the seat surface/carrier assembly in a mold and overmolding a frame onto a periphery of the seat surface/carrier assembly.

A method of upholstering a seat having a seating frame, and a corresponding attachment assembly, comprises providing a diaphragm generally having a weave of warp and weft yarns with an attachment member for installation of the diaphragm to the seat. The attachment member comprises an adapter strip and a coil member. The coil member is adapted to be intertwined with the weave of the diaphragm and thereafter inserted into and held by the channel in the seating frame. The adapter strip may be connected to the coil member to facilitate feeding the assembly through the channel in the seating frame. Alternately, the adapter strip can replace the channel in the seating frame and instead provide a mounting structure to which the diaphragm can be attached through the coil member's engagement with the adapter strip. A retainer sheet may also be used to maintain a desired tension of the diaphragm during installation.

An apparatus for upholstering a truss allows an operator to staple a fabric web to the truss, rotate the truss, further staple the semi-finished truss and cut the fabric web. The truss is fully upholstered after the end surfaces of the truss are wrapped up in fabric and the fabric stapled in place. The apparatus may accommodate different size trusses. A web of fabric is pulled around at least one roller in the apparatus by rotation of two vise mechanisms on opposite sides of the truss.

A seating furniture support arrangement (6) for a seat or a backrest, suitable, e.g., for a sofa, comprises a first (8) and a second (10; 12) load-carrying longitudinal beam, each being mountable to a seating furniture frame comprising one or more parts; an elastic sheet (16; 14); and a mechanism for stretching the elastic sheet (16; 14) between the first longitudinal beam (8) and the second longitudinal beam (10; 12). The mechanism comprises a first longitudinal beam (8) pivotable on the frame. The elastic sheet (16; 14), with the said seating furniture support arrangement (6) in installed position, is connected to the first longitudinal beam (8) in such a way that the first longitudinal beam (8) pivoting with respect to the frame, in response to an application of an external force or torque, stretches the elastic sheet (16; 14), the external force or torque working against the tension force of the elastic sheet (16; 14) until a point of maximum tension is reached, past which point of maximum tension the tension force facilitates further pivoting of said first longitudinal beam (8), acting to keep the first longitudinal beam (8) in place in a final position.

A wool mattress set includes a receiving mattress including a wool filling enclosed in a first envelope, combined with a base mattress comprising a foam filling enclosed in a second envelope. The wool filling of the receiving mattress includes a stack of one or more superposed wool mat layers, essentially devoid of wool flakes, and the receiving mattress is laid on the base mattress, the receiving mattress and the base mattress being independent and separable from each other. The foam filling of the base mattress, whose density is at least 35 kg/m.sup.3, can include in particular a material originating from foam recycling.

A seat includes a seat surface having a periphery and a carrier overmolded onto the seat surface over the periphery. The carrier has a periphery and a frame is overmolded onto the carrier over the carrier periphery. The seat is assembled without fasteners. A method for making the seat includes overmolding a carrier onto a periphery of a seat surface to form a seat surface/carrier assembly, tensioning the seat surface/carrier assembly in a mold and overmolding a frame onto a periphery of the seat surface/carrier assembly.

A fastening device for fastening a mattress to a mattress support and a bed, in particular a hospital bed, having such a fastening device. The mattress support has multiple support sections which are articulated to one another. In a central section of the mattress support there is a support panel having first holding cut-outs. In a lower leg section of the mattress support there is a support panel having second holding cut-outs. The first holding cut-outs are assigned first fastening elements fastened to the mattress, and the second holding cut-outs are assigned second fastening elements fastened to the mattress. The first fastening elements are fastened to at least two first planar holding parts which are situated on opposite sides of the mattress in a transverse direction of the mattress, forming a transverse distance. The second fastening elements are preferably arranged on a single common second planar holding part which extends over more than half the mattress width in the transverse direction of the mattress, preferably over virtually the whole mattress width.
