The invention discloses a sofa seat frame, a sofa base assembly, a sofa and a sofa production and assembly process, the sofa seat frame comprises two cross beams arranged at intervals and two longitudinal beams connecting the two cross beams, wherein a plurality of supporting elastic pieces are arranged between the two cross beams; and each longitudinal beam comprises a first supporting plate for supporting a seat cushion and a first side plate arranged at one side of the lower part of the first supporting plate and used for being detachably connected with sofa fabric on the seat cushion. In the sofa seat frame provided by the invention, when the seat cushion is placed on the supporting elastic pieces, the first supporting plates can give a certain supporting force to the seat cushion, so as to improve the sitting comfort of users.

The disclosure relates to a sofa armrest. The sofa armrest includes a main body made by blow molding, the upper end of the inner side surface of the main body is recessed inward to form a fabric mounting groove for mounting armrest fabric, and the lower end of the inner side surface of the main body is provided with clamping-connection grooves for being connected with connectors of a sofa underframe. The sofa armrest is made by a blow molding process, and compared with traditional solid sofa armrests, the sofa armrest has the advantages of low weight, high production speed and less manufacturing materials; when the armrest fabric is squeezed and deformed, debris accumulates on the lower wall of the fabric mounting groove or on a seat cover fabric, cleaning of dust and debris is facilitated, and the overall hygiene of a sofa is maintained.

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 removable cushion for a chair having an outer surface and an inner foam, as well as at least one magnetic member. The inner foam and the outer surface are formed from the same polymer, with the outer surface forming an integral skin over the inner foam. The outer surface defines an upper surface and a lower surface. The lower surface is structurally configured to be positioned in an abutting relationship with a seating surface of a chair. The at least one magnetic member is embedded within one of the outer surface and the inner foam, the at least one magnetic member positioned closer to the lower surface than the upper surface of the outer surface. A chair having the cushion, and a mold is likewise disclosed, as is a method of manufacturing the cushion.

In a clip for engagement of an outer layer, the outer layer covering a foam member in a state held by the foam member being caught to a foam member side by engagement of an engaged portion provided at a rear side of the outer layer, the clip includes a base configured to be held by the foam member, a pair of projection walls erected on the base and facing each other, engagement portions extending from the projection walls in a width direction of the projection walls, and arranged to be swingable substantially parallel to the base or horizontally, wherein the engaged portion is configured to be sandwiched between the engagement portions to elastically engage. Accordingly, since the engagement portion bends horizontally relative the base, the overall height can be made low.

A seating arrangement includes a base, a seat assembly operably coupled to the base, and a back assembly that includes a substantially rigid back frame including a pair of side portions spaced from one another and extending upward from the base, and a substantially flexible back shell including a front surface and a rear surface opposite the front surface, a plurality of laterally-extending slots that extend between the front surface and the rear surface and that cooperate to define a plurality of laterally-extending ribs therebetween, where a pair of laterally-extending ribs of the plurality of laterally-extending ribs are connected to one another via a vertically-extending rib located at a substantial midpoint across a width of the back shell, and wherein the back shell is coupled to each of the side portions of the back frame at locations above the plurality of laterally-extending slots.

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 suspended fabric seat includes a frame, a woven fabric suspended in the frame and a plurality of compression limiters attached to the woven fabric. The woven fabric is formed from monofilament fibers that are oriented in a first direction and textile fibers oriented in a second direction transverse to the first direction. The plurality of compression limiters are oriented in the first direction and are formed from a material compatible with the woven fabric. A method for making the suspended fabric seat is also disclosed.

Provided is an iron sofa frame structure provided with a base, two supporting plates oppositely disposed, configured to support a soft package and be connected with a sofa fabric and two driving link sets respectively configured to connect the two supporting plates to the base, wherein a front rod and a rear rod are correspondingly disposed at intervals between the two supporting plates, and several elastic bearing pieces for bearing the soft package are disposed between the front rod and the rear rod. The supporting assembly is directly combined to the iron sofa frame structure, so that a structure in which an additional seat-wrapped frame is introduced to support the soft package is rejected, an existing iron sofa frame structure and a production process of an iron sofa frame are simplified, the assembling and production efficiencies are increased, materials are saved, and the cost is reduced.

A vibrotactile support with suppressed distortion and destructive interference having a rigid frame within which is tensioned a high-density material panel in a supportive configuration. A low-durometer, high specific gravity material user interface pad is placed on the high-density panel on the user-supporting side and a plurality of acoustic drivers are attached to the opposing side of the high-density material panel to transmit vibrations through the high-density material panel, the pad, and the user's skin. The acoustic drivers are supplied from an amplifier which is supplied from an electronic audio source. The amplifier may also drive a set of headphones for the user. The audio source may be from any known electronic audio source, including audio-visual presentations. Various shapes and configurations of the vibrotactile support are possible. For non-limiting examples, the vibrotactile support may be configured as a lounge chair, upright chair, baby cradle, or flat bed.
