An easily-assembled desk foot and a height-adjustable desk, the desk foot including: a desk foot body, which is internally hollow; an insertion opening at each end of the body and a connection hole on the desk foot body for connecting a lower end of a lifting column; and an end cover assembly at each end of the body, with insertion portions matched with the insertion openings of both ends of the body. The bottom of the insertion portion is connected with a support portion protruding downwardly and extending along a length direction of the insertion portion. The insertion portion and the support portion are integrally formed. When the insertion portion of the end cover assembly is inserted into the insertion opening, the support portion is supported at the bottom of the body. The height-adjustable desk according to the above technical solutions is simple and cost-saving to produce.

A cone assembly for furniture or interior accessories is provided. A plurality of cones is arranged in a linear array to form the cone assembly, wherein an inner cone is received by at least one outer cone; and wherein the outer cone is made of a first layer of material being different from the material of the inner cone.

An adjustable-height folding table adapted to be expanded to an unfolded configuration when being used and collapsed to a compact folded configuration when not being used for purposes of transport or storage. The folding table has a first plurality of legs extending between the table top and a corresponding plurality of footpads and a second plurality of legs that are pivotally coupled to respective ones of the footpads. The second plurality of legs are rotatable relative to the footpads between a first position extending downwardly from the footpads and away from the top of the table and a second position extending upwardly from the footpads and towards the table top. The second plurality of legs are rotated to lay on the ground in their first position, and the footpads lay on the ground when the second plurality of legs are rotated to their second position.

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.

The present invention provides an extension connecting structure for mounting onto a chair leg. The extension connecting structure includes a connecting plate, a base plate and a connecting part. An end of the connecting plate is connected to the base plate. The connecting part is disposed at another end of the connecting piece. The connecting part is configured to mount the chair leg. As such, the supporting strength of the chair leg may be reinforced by the connecting plate and the base plate. In such a way, the chair may be prevented from falling backwards due to the unstable center of gravity, and the user may be prevented from getting injured.
