A frame structure (100) for a piece of furniture comprising struts (1) which are capable of forming legs (101) of the piece of furniture, cross-pieces (2) which connect, in accordance to a grid-like structure, the struts (1), and connection means (300) which are configured to join the struts (1) and the cross-pieces (2), wherein the connection means (300) comprise at least two bent extensions (21, 22) which are capable of engagement in corresponding seats (11, 12) which are formed in the strut (1) and in the cross-piece (2), respectively, or vice versa, and further comprising a fixing element (3) which includes an abutment surface (30), a threaded seat (31) and a corresponding screw (4) which has a head (40) which is capable of an approach movement towards/withdrawal movement from the abutment surface (30) by means of screwing in the threaded seat (31), the fixing element (3) being configured in such a manner that the abutment surface (30) and the head (40) of the screw (4) abut the strut (1) and the cross-piece (2), respectively, or vice versa, as a result of the mutual approach/withdrawal movement.

A method of adjusting the inclination of a furniture leg and a mounting set including a base part, a mounting part, a fixation means, and a furniture leg. The base part comprises a first truncated cone element with an inclined surface. The mounting part includes a second truncated cone element having an inclined surface with a connecting element for detachable connection of the furniture leg. The fixation means prevents rotational movement between the base part and the mounting part. The mounting part is detachably fixated to the base part for allowing the mounting part to be rotated relative to the base part for adjusting the inclination angle of the furniture leg relative to the vertical plane being perpendicular to the planar underside of the furniture.

A frame corner member includes an elongated hollow extrusion having a central corner portion and two leg portions extending from the central portion. Each leg portion includes an inner side wall spaced from and parallel to an outer side wall, and merging with the central portion. An outer end wall joins the inner and outer side walls, which each include an inner surface facing the inner surface of the other side wall. An opening through the outer end wall defines a space between the inner and outer side walls adjacent one end of the extrusion for receiving one end of one of frame side members and end members. At least one of the inner surfaces in the space has discrete surface features adapted to grip and retain the one end of one of the side members and end members in the space when received through the opening.

A bedhead frame and a bed frame structure having the bedhead frame are provided. The bedhead frame includes two vertical rods arranged symmetrically and at least one horizontal rod connected between the two vertical rods. Each of the vertical rods is an L-shaped structure. The horizontal rod and the vertical rods of the bedhead frame are detachable, which can be transported or stored conveniently. In particular, the vertical rods of the bedhead frame employ an L-shaped structure. When a mattress is installed to the bed frame structure having the bedhead frame, both sides of the mattress are just between upright sides and horizontal sides of the two vertical rods, thereby preventing the mattress from shifting.
