A novel sling assembly and corresponding method of stretching sling fabric are disclosed. The assembly preferably comprises a chassis with opposing rails connected by a cross bar. A sling frame having opposing stretch bars connected by a stretchable fabric is disposed over the chassis in a pre-assembled position. A cam lock is inserted into a key hole cut into at least one of the rails; the cam lock is then rotated away from the central axis of the key hole. An engagement member extending from at least one of the stretch bars is then inserted into the key hole. The sling fabric may now be stretched by rotating the cam lock toward the central axis of the key hole to move the engagement member along the key hole until the fabric is taut. The taut fabric is held in place by the engaged cam lock, whereby the assembly is kept in its stretched, fully assembled position. The invention's unique structure thus advantageously makes sling fabric replacement convenient, quick, and without the need for special tools.

A mattress top for an innerspring mattress comprising an upper section including an outer decorative fabric layer and an inner foam layer and a lower section including an array of micro-springs to support the upper section wherein the periphery of the upper section and the periphery of the lower section are stitched together to form an unitary mattress top.

A body support assembly includes a seat assembly and backrest assembly supported by tilt control assembly. Methods of using and assembling the body support assembly are provided.

A sling chair may include a frame having one or more side rails, each side rail having a J-channel, and a fabric having one or more edges. The J-channel may include a neck and a foot, and be configured to receive a rod connected to a fabric edge. A locking strip may be inserted and force fit into the J-channel to lock the fabric edge and rod in the J-channel. The locking strip may include one or more lateral protrusions for mating with a ridge along an inner surface of the side rail.

A chair component assembly includes a support component adapted to support a portion of a seated user, and a cover including a plurality of sides that cooperate to form an interior space that receives the support component therein, the cover further including a support component receiving aperture and a flap movable between an open position where the support component may be moved from an exterior of the cover to the interior space of the cover, and a closed position where the flap covers the support component receiving aperture, and wherein the flap is secured to the support component by a quick-connect fastener.

A cover-material fastening clip includes a locking portion having a guide piece and a hook which includes an extension portion and a distal end portion. The guide piece extends includes a bent portion bent and extended toward the distal end portion. An insertion opening having a predetermined gap and allowing a wire to be inserted therethrough is positioned between the bent portion and the distal end portion. A distal end portion of the guide piece extending from the bent portion is an elastic piece portion being elastically deformed to be spaced from the distal end portion and to widen the insertion opening. In a part of the locking portion, which is located within a range, in which the elastic piece portion can be elastically deformed and thus moved, an escape space is provided to allow a distal end of the elastic piece portion to be positioned therein.

A mattress having variable height and hardness is disclosed. The mattress comprises a base layer held by a mattress cover using an extendable attachment system. The mattress further comprises one or more top layers made of resilient material which are stacked on top of the base layer. Only friction between the material of the top layers limit the lateral or longitudinal movements of a layer with regard to another layer.

A seating structure includes a frame, a carrier, and a suspension material. The frame includes first and second side frame members spaced apart in a first direction and defining an opening therebetween. The first and second side frame members have an inner portion facing the opening and an outer portion facing away from the opening, the outer portion including a plurality of first attachment features facing away from the first and second side frame members in the first direction. The carrier includes first and second side carrier members. The first and second side carrier members include a plurality of second attachment features facing the first and second side frame members in the first direction, the plurality of second attachment features engaging the plurality of first attachment features to attach the carrier to the frame. The suspension material is attached to the carrier and extends over the opening in the frame.

An edge strip (10) is provided for a seat cover (6, 20). The edge strip (10) includes an edge strip core (10.1) that is surrounded, in particular cladded, by a fastening material (10.4). A seat cover (6, 20) is provided for a seat (5) and includes the edge strip (10). A seat (5) is also provided that includes the seat cover (6, 20).
