A foldable chair, comprising a seat portion and a telescopic side wall includes rings of varying diameters consecutively arranged. A topmost ring is mounted to a bottom surface of the seat portion and has a smallest diameter. A bottommost ring has a largest diameter. In deployed position, the telescopic side wall is opened or partially folded to set and lock a desired height of the chair. In fully retracted position all of the rings are disposed adjacent the bottom surface of the seat portion. Each ring is an integral unit configured with a locking arrangement that selectively locks it to an adjacent ring. In some embodiments, a security lock centrally disposed along a height of the chair substantially perpendicular to the varying diameters of the rings secures the locking arrangement. A table uses the foldable chair as a leg and can store several, for example four, foldable chairs.

A foldable and height-adjustable table may include a main frame, a foldable frame, and a wheel assembly. The main frame has two side frames which are separated with a distance and parallel with each other. Each of the side frames has a vertical front sleeve and a vertical rear sleeve, and each of top bars horizontally located at a top end of the side frame. A table top has a pivotal side edge pivotally coupled with one of the top bars and an opposed detachable side edge detachably coupled with another top bar. The table top is configured to be coupled on tops of the top bars for use or pivotally turned over to couple at an outer edge of the side frame for store, and the main frame is configured to be folded between the folded position and unfolded position.

The disclosure relates to a foldable desk, comprising a first foldable panel connected to a support panel capable to be folded towards the first foldable panel, and multiple second foldable panels. If the first foldable panel and the second foldable panels are folded, the first foldable panel, the second foldable panels and the support panel can be overlapping each other. If the first foldable panel and the second foldable panels are unfolded, the second foldable panels can be inserted into the support panel so that the second foldable panels are placed perpendicular to a lower surface of the first foldable panel, and an upper surface of the first foldable panel forms a desktop.

The present invention discloses a folding shelf for placing a box with a built-in liquid crystal panel in multiple layers, the folding shelf including: a first frame assembly, the first frame assembly including a rectangular first frame assembly body and four first support columns erected at a lower end of the first frame assembly body, the first frame assembly body comprising two first fixing beams and two first connecting beams disposed between the two first fixed beams, wherein the first support column comprises a first cylinder and a second cylinder, the first cylinder is erected at an upper end of the second cylinder, an upper end of the first cylinder is folding connected to a lower end of the first fixed beam, a lower end of the first cylinder is folding connected to the upper end of the second cylinder.

An inflatable sleeping pad or air mattress comprises an inflatable pad having a top layer and a bottom layer. At least one middle layer is disposed parallel to the top and bottom layers, and supported between the top layer and the bottom layer by a plurality of support baffles, wherein a first plurality of support baffles is disposed between the at least one middle layer and the top layer, and a second plurality of support baffles disposed between the at least middle one layer and the bottom layer. The sleeping pad further comprises an air inlet/outlet valve disposed on at least one of the inflatable pad top or bottom layers.

A table that can be easily transported and stored and in operation provides a stable surface that can withstand substantial vibration as well as stability when supporting substantial weight or loads that may move along the top of the table or shift in position without the legs buckling or moving out of their supporting position or causing the table to tilt or fall to the side.

A foldable tray includes first and second base sections (BSs), lateral side members (LSMs) and a locking device. Each BS comprises opposed lateral edges, an inboard edge and a rigid hard surface. They are adjacent along their inboard edges, and foldable along those edges between an extended position where the hard surfaces lay in a plane and a folded position where the surfaces are stacked. The LSMs are attached along the opposed lateral edges of each of the BSs and foldable along that attached edge between an upright position where the LSM is at a substantial angle to the hard surface of its attached BS and a portable position where it is either stacked with its attached BS or has a major surface lying in the same plane as the hard surface of its attached BS. The locking device retains the BSs in the extended position only when engaged.

A table tennis table includes a table top and a base assembly. The base assembly includes legs that are adjustably spaced so that the base assembly has an adjustable length and an adjustable width. Each leg includes a telescoping pole that extends between a table pad and a floor pad. One or more struts extend from each leg to adjacent legs along the length and the width of the base assembly. The adjustable legs may be used to configure the base assembly between a collapsed configuration and an expanded configuration which has a greater length and width than the collapsed configuration. When the base assembly is configured in the expanded configuration, the legs of the base assembly may be used to support the table top to create a to playing surface for table tennis.

A foldable chair, comprising a seat portion and a telescopic side wall includes rings of varying diameters consecutively arranged. A topmost ring is mounted to a bottom surface of the seat portion and has a smallest diameter. A bottommost ring has a largest diameter. In deployed position, the telescopic side wall is opened or partially folded to set and lock a desired height of the chair. In fully retracted position all of the rings are disposed adjacent the bottom surface of the seat portion. Each ring is an integral unit configured with a locking arrangement that selectively locks it to an adjacent ring. In some embodiments, a security lock centrally disposed along a height of the chair substantially perpendicular to the varying diameters of the rings secures the locking arrangement. A table uses the foldable chair as a leg and can store several, for example four, foldable chairs.

A two-piece table includes a one-piece tabletop portion and a one piece table leg portion. The tabletop portion is made of four or more distinct independent, hinged segments which allow the tabletop fold, origami style, into a small package. The tabletop further includes four corners having various chamfered ends or corners which allows for the creation of a handle in the longer ends or corners of the tabletop. The table leg portion is a foldable, unitary structure including four legs and a top portion on which the table top rests without any attachment. The top portion of the table leg portion fits into a slot or groove on the underside of the tabletop. The table leg portion is hinged and folds into a square.
