An adjustable desk easy to disassemble comprises: a crossbeam used as a bearing structure of the adjustable desk; two desk legs disposed at two ends of the crossbeam, pivotably connected to the crossbeam and used to stabilize relative positions of the desk legs and the crossbeam through first locking parts; and two brackets disposed at the two ends of the crossbeam, fixed to the crossbeam through second locking parts. When the adjustable desk needs to be assembled or disassembled, the first locking parts and the second locking parts are removed to allow the two desk legs to rotate towards or opposite to each other to complete assembly or disassembly of the adjustable desk.

A table comprising an upper surface and a lower surface attached to the upper surface via an attachment means, at least one table support attached to the lower surface, and at least one table support attached to the upper surface.

A table with a central extension includes a chassis two movable trays bearing on the chassis and adapted to be moved closer to each other to constitute on their own one continuous surface, or separated symmetrically from one another, or one independently of the other to allow the set-up of one or several central extension(s) between the movable trays. The chassis is made up of two spars of variable length, two cross-beams, the cross-beams and spars assembled perpendicularly in pairs to form a horizontal frame, and four legs extending at the four corners of the frame below the latter. Each spar includes two portions, a fixed spar and a movable spar, the spars being made up of a profiled tube with a rectangular cross-section in which extends a slide with a rectangular cross-section and have a longitudinal central groove.

An extendable table assembly includes a primary board, a support unit mounted on the primary board, a foldable primary stand pivotally connected with the support unit, an extension unit arranged under the primary board and connected with the support unit, a secondary board placed on the extension unit, and a connecting unit mounted between the support unit and the extension unit. The extension unit includes a strut, an enclosure frame connected with the strut and the support unit, and a foldable secondary stand movable with the extension unit. The secondary stand includes two legs pivotally connected with the enclosure frame and a V-shaped brace mounted between the two legs and the strut. The two legs cooperate with the primary stand to support the primary board.
