An article of furniture including a base, a plurality of panels forming an outer surface of the article of furniture, and a plurality of struts for securing the panels in place. The base has an outer periphery which is securable to at least some of the panels. The base is configured for placement on a floor surface. Further, each strut has an elongated member configured for securement to at least two adjacent panels which are oriented in different planes from one another. The adjacent panels are secured to the respective struts with removable fasteners.

A seating configuration is described. The seating configuration includes a first support surface configured to support the Ischial Tuberosities of a user. The first support surface includes a feature to urge a user into an optimal position on the seat. The seating configuration includes a second support surface positioned adjacent a pelvic-sacral-lumbar region of the user. The seating configuration includes a third support surface positioned adjacent a thoracic-cervical region of the user. The first, second, and third support surfaces, respectively, together can be configured to create a natural alignment of a spinal column of the user.

A chair having a first frame portion with a backrest support and a rear leg portion at least part of the backrest support and the leg portion being formed from a single piece. A second frame portion has a seat support and a front leg portion extending in a direction transverse to the seat support, the seat support in a fixed position relative to the backrest support. The backrest support molded thereover in foam, the backrest support being substantially peripherally located around the foam of the backrest and the backrest being provided free from rigid supports extending across a middle portion of the backrest.

Device for linking bodily movement to learning behaviour, whereby this device (1) consists of a number of objects that can be used by pupils as flexible adjustable seating units (2), characterised in that these seating units are each equipped with a digital module (4) that is able to detect movements of the seating unit caused by the pupils, and to communicate these movements wirelessly to a central teaching module (3), after which the central teaching module (3) can wirelessly send back an individual message to each of the seating units (2), adapted to the movement that is made with each of the seating units.

A method for producing a seat core material that has a foamed molded substrate and a frame member embedded in a periphery thereof, which includes, as step (a), heating thermoplastic resin expanded beads in a mold cavity, in which the frame member has been disposed, to fusion-bond the expanded beads to each other and to obtain the foamed molded substrate with the frame member being embedded in the periphery thereof; and, as step (b), simultaneously with step (a) or after step (a), forming a void cavity S, S in the foamed molded substrate at a position along and adjacent to the frame member. The void cavity S, S has a size and shape that allows a relative displacement between the frame member and the foamed molded substrate when the foamed molded substrate shrinks after step (b).
