A lumbar pillow of height 9 to 11 cm has outer and inner cushioning members, with a hollow space formed in the outer cushioning member. The inner cushioning member has an identical cross-sectional shape as the hollow space. The load X for the user having the lumbar pillow placed under the user's lower back equals a value obtained by multiplying the user's weight by a coefficient 0.59. A preferable range of the amount of displacement against the load is defined. The comfort of the lumbar pillow may be determined on the basis of sensory evaluation including evaluation of the texture during use, and the lumbar pillow can be used for a long period of time. The physical properties may be visualized by providing a plurality of settings to provide a substantially straight load-displacement line, enabling any user to choose a suitable pillow regardless of race, gender, and weight.

An upholstered piece of furniture with a frame including a pair blow molded hollow arm rest forms, wherein spanning wood frame members extend between the forms. The wood frame members secured to the forms with interference fits, and minimal threaded fasteners. The arm rest forms have through slots which allow the seat deck and arm upholstery to be pulled through and anchored with staples providing a secure attachment. Threaded fasteners clamp onto the polymer wall of the forms for attachment of frame members. A blowmolded backrest has a metal reinforcing arms connecting to a seat platform. Holes in arm rest allow upholstery panel connections with Christmas tree connectors. The connections to the arm rest forms and providing a geometrically rigid and robust sofa frame that is weighs less, is quicker to assemble, and is more robust. The finishing of the sofa is also quicker and easier than conventional sofas.

A portable therapeutic unit and system for treating a back, a neck, or the back and the neck of a user is disclosed. The therapeutic unit includes a first seat, a back support, a hinge, and a metal back. The first seat is designed for the user to sit thereupon. The back support is designed to support a back of the user. The hinge pivotally connects the first seat and the back support. The metal back is connected to the back support, with the metal back magnetically coupling with an attachment magnet. Further, the attachment magnet couples to a therapeutic aid to deliver treatment to the user.

A support unit for use on an article of furniture includes an adjustable support structure displacably mountable to the article of furniture and a cushion member carried by the support structure. The support structure is configured to be arranged in a first orientation relative to the article of furniture for enabling the cushion member to adopt a first position relative to the article of furniture and in a second orientation (46) relative to the article of furniture for enabling the cushion member to adopt a second position relative to the article of furniture.

A system for supporting the human body or a human body segment is provided. The system comprises a base element having a substantially flat shape, and one or more pluralities of shaped modular elements. The base element is flexible, so that it can be brought from an operating, extended configuration to a non-operating, folded configuration. The support system comprises one or more stiffening elements, which are designed in such a way that, on the one hand, they provide the correct stiffness to the backrest when in the operating configuration, and, on the other hand, they do not prevent the possibility of folding the backrest when in the non-operating configuration. The support system can, for example, be made in the form of a seat, a backrest, a mattress, or the like.

A folding chair includes front and rear supports that fold and/or retract into central beams to reduce the space occupied by the chair in a folded configuration. A backrest is coupled to the central beams with a hub that allows an angle of the backrest relative to the central beams to be selected and for the backrest to be folded flat relative to the central beams. One or more actuators and pin actuators may control the relative movements of the backrest, front support, rear support, and central beams.

A support for a chair includes: a base plate (110); support plates (120, 130), of which one sides are rotatably coupled to the base plate (110); and a first hinge (150) which connects the base plate (110) and the support plates (120, 130) to be rotatable, wherein the base plate (110) is supported by a seat portion (11) of a chair (10) and the support plates (120, 130) are supported by a back portion (12) of the chair (10) while the base plate (110) and the support plates (120, 130) are unfolded at a first maximum unfolding angle (θ1m) and support the upper body of a user.

A tensioning strap, the stiffness of which can be varied in a wide range of values, is provided. The tensioning strap comprises a base body, made as a strip of flexible material, and one or more stiffening elements applied to the base body. The stiffening elements can be applied to the base body in a permanent, non-removable manner, or, in a removable manner. In this way, the stiffening elements can be applied, removed, displaced, replaced with stiffening elements of different types depending on the needs. The tensioning strap finds particular, though non-exclusive, application in the making of a system of tensioning straps for a system for supporting a human body or a segment thereof.

A connecting structure and a seat. The connection structure comprises a mounting hole structure and a mounting structure correspondingly disposed on two main members to be connected; a step structure extends downwards and inwards on one side of the mounting hole structure, and two sides of the step structure are provided with limiting clamping points protruding in a direction parallel to an extending direction of the step structure; the mounting structure is configured to be a column structure, a bottom end of the column structure is provided with a shovel-shaped structure extending in one side of the column structure, and two sides of the shovel-shaped structure are provided with everted protrusions.
