The furniture described consists essentially of a structural member made of wood and incorporates high-frequency metals, including a selection from copper, silver, gold, zinc, magnesium, titanium, and platinum. Upholstered in a high-frequency fabric, options for this upholstery include cotton, silk, linen, wool, bamboo, hemp, or Tencel (Lyocell). Inside the furniture, multiple high-frequency crystals are strategically placed within internal compartments. In addition, copper balls may be positioned in close proximity to the high-frequency crystals to amplify their high-frequency affects.

A sofa includes: a base; a backrest assembly including a backrest frame having a front side and a rear side, and a first flexible sheet. The backrest frame is directly or indirectly connected to the base. The backrest frame has a lower end spaced a distance from the base. The first flexible sheet is connected to the front side of the backrest frame and extends from the backrest frame to and detachably connected to the base.

It is of interest to be able to adjust the upholstery firmness of furniture for sitting and lying on as individually as possible, in particular with a view to being able to use the furniture for a long time. In addition, there is a need for a design which allows firmness adjustment to be integrated and which can be realized as flexibly as possible for different furniture or seat variants. The invention provides an upholstered-furniture arrangement (100) which has a basic frame (7) and an upholstered cushion (6) on which someone can sit or lie, which is fixed to the basic frame at least in the edge region thereof and which has a panel (4) beneath it for upholstery-firmness adjustment, the panel being arranged in the basic frame (7) such that the height of the panel can be adjusted by pivoting the panel, wherein the end of the panel (4) located opposite a pivot shaft (14) is arranged freely in the basic frame (7), and a height-adjustment device acts on the panel (4) from beneath by applying an adjustable compressive/prestressing force (F), the height-adjustment device being supported in the downward direction by the basic frame, counter to the compressive/prestressing force. This arrangement has an attractive, direct technical effect and offers a good compromise between cost and benefit.

A sofa structural frame comprises a plurality of sofa modules, seat frame components, splicing pieces and supporting pieces which are combined to form a sofa frame, wherein the sofa modules comprise a backrest frame and armrests made by a molding process, the armrests are arranged on the two sides of the backrest frame by the splicing pieces, and the seat frame components are arranged between the armrests on two sides by the supporting pieces; connecting parts are formed on the surfaces of the armrest and the backrest frame; a mounting part is formed on the surface of the armrest; the splicing pieces comprise a first connector and a second connector which are connected with each other; the supporting pieces are configured to be connected with the mounting part and the seat frame component respectively in a clamping manner.

The present invention provides a combined sofa and relates to the technical field of sofa assemblies. The combined sofa includes: an H-shaped middle frame, where two groups of sofa plate seats are fixedly disposed above two sides of the H-shaped middle frame through a bolt; an arc-shaped buckle structure is disposed on a front side edge of the sofa plate seat in a welding manner, and a front support foot is fixedly disposed in the arc-shaped buckle structure through a screw; and a middle back frame is fixedly disposed on rear sides of the two groups of sofa plate seats through a bolt. In the present invention, the H-shaped middle frame, the sofa plate seat, the front support foot, the middle back frame, a side back frame, and an arc-shaped handrail are assembled and connected through a bolt.

A furniture may include a frame structure and a seat cushion arrangement. The frame structure may include an elongated platform. The seat cushion arrangement may be supported by the platform in a first operative state in which at least a substantial portion of an elongated upper surface of the seat cushion arrangement is inclined in relation to a horizontal plane (HP) for establishing an elongated sitting area for a plurality of users. The seat cushion arrangement may be supported by the platform in a second operative state in which a substantial portion of an upper surface of the seat cushion arrangement is in parallel with the horizontal plane for establishing an elongated lying area for at least one user, wherein the lying area has a direction between a head end and a foot end in parallel with a longitudinal direction of the platform.
