A chair comprises: two side frames, each of the two side frames comprising a front supporting leg and a rear supporting leg; a seat portion fixed between the two side frames; and a backrest portion connected to the rear supporting legs of the two side frames via a plug structure.

A chair comprising two facing and cooperating sidepieces (11), bar-type connection means to correctly and stably distance the two sidepieces (11), and, during use, a backrest (13) and a seat (12); the bar-type connection means, the backrest (13) and the seat (12) connect the two sidepieces (11) transversely in a stable manner.

A removable swim-up dock bar is described. The dock bar is removably attachable to a submerged foundation of an existing dock and may have adjustable seats or adjustable legs to ensure proper height and stability.

Provided is an iron sofa frame structure provided with a base, two supporting plates oppositely disposed, configured to support a soft package and be connected with a sofa fabric and two driving link sets respectively configured to connect the two supporting plates to the base, wherein a front rod and a rear rod are correspondingly disposed at intervals between the two supporting plates, and several elastic bearing pieces for bearing the soft package are disposed between the front rod and the rear rod. The supporting assembly is directly combined to the iron sofa frame structure, so that a structure in which an additional seat-wrapped frame is introduced to support the soft package is rejected, an existing iron sofa frame structure and a production process of an iron sofa frame are simplified, the assembling and production efficiencies are increased, materials are saved, and the cost is reduced.

A chair has a seat with a seat shell. A frame for supporting the seat has, on its side facing the seat, a mounting strut running parallel to the plane of the seat shell. An underside of the seat shell if formed with a receiving profile for the mounting strut. The receiving profile has a fastening section extending from a circumferential edge of the seat shell parallel to a plane of the seat shell into the interior of the seat shell and having an access opening at the circumferential edge of the seat shell. A clamping strip is provided for clamping the mounting strut in the fastening section. The clamping strip is slid from the access opening in a direction parallel to a longitudinal direction of the fastening section and is fixed in its end position in the fastening section perpendicular to the plane of the seat shell.

A chair has a metal base, a matrix of metal tubes having a common outside and an inside diameter, welded orthogonal to the metal base, extending vertically, and a matrix of posts matching the matrix of metal tubes, the posts bored for a portion of a length of each post, with each post engaged over one of the metal tubes. The chair is characterized in that one row of posts along one edge of the metal base comprises posts of a height greater than other posts, and forms a backrest for the chair, and in that the remaining matrix of posts, of a lesser height than the posts forming the backrest, are of a common height, and form a seat surface for the chair.
