A method of assembling a set of panels, to obtain an assembled product, including connecting a first edge of a first panel, with a first main plane, to a first edge of a second panel, with a second main plane, including arranging a third panel with a third main plane perpendicular to the first main plane, arranging a first edge of the third panel at a second edge of the second panel and arranging the third main plane with a second angle in relation to the second main plane; connecting the first edge of the third panel to the second edge of the second panel, by displacing the third panel and/or the second panel; and connecting a second edge of the third panel to a second edge of the first panel and connecting the first edge of the third panel to the second edge of the second panel.

A furniture assembly system (10), comprising: a plurality of cross panels (100,100a), wherein each cross panel comprises a plurality of engaging apertures (102) of a right-angle cross shape arranged in one or more rows and one or more columns, with each engaging aperture being separated from an adjacent engaging aperture at a predetermined distance, at least one top panel (300) comprising a plurality of lock-down apertures, at least one support member (200,200a,200b), wherein the or each support member comprises a first interaction edge (201) and a second interaction edge (202) connectable to the cross panel, and a third interaction edge (203) connectable to the top panel, the first interaction edge and the second interaction edge being substantially perpendicular to the third interaction edge, and
wherein each of the first interaction edge and the second interaction edge comprises at least one hook joint (210) shaped and sized to be insertable into the engaging aperture of the cross panel and to extend beyond the cross panel forming a cantilevered projection, the third interaction edge comprises one or more protruding portions (220) shaped and sized to fit in the plurality of lock-down apertures (304) of the top panel.

The module comprises at least two front and rear chassis-frames, each with two right and left uprights and two top and bottom crosspieces, two right and left side walls inside the frames and a floor inside the frames bearing against the bottom crosspieces of the frames. The floor is arranged to oppose the movement of the bottom portions of the side walls towards each other. The uprights of the frames are arranged to oppose the movement of the side walls away from each other. The top portions of the side walls and the top crosspieces of the frames are arranged to oppose the movement of the side walls towards each other.

A shelf system includes at least one modular shelf assembly including at least one shelf unit, a plurality of support posts, an adjustable foot, covers, and anchors. The at least one shelf unit, plurality of support posts, adjustable foot, covers, and anchors are, in combination, adapted to create the modular shelf assembly. Each shelf unit is adapted to receive the plurality of support posts, including one support post generally located adjacent a rear side of the shelf unit about half-way between a first and a second end of the shelf unit.

An adjustable truss structure is provided and includes a truss member with a first channel attached to the truss member, the first channel having a first slot, and a rail having a second slot with an anchor attached to the rail. The anchor has a member rotatable to a first position where the member is insertable into the first slot and rotatable to a second position to engage with a surface of the first channel, enabling the rail to be selectively moved relative to the first channel and locked into a fixed position relative to the first channel.
