Systems and methods comprising: cause first legs to rotate towards the center of the table until the first legs reside adjacent to the upper or lower part of the table; cause the first legs to slide against the upper or lower part in a first direction away from the center of the table until second ends of the first legs are received into openings formed in first couplers coupling the first legs to the upper part; cause the second legs to rotate towards the center of the table until the second legs reside adjacent to the upper or lower part of the table; and cause the second legs to slide against the upper or lower part in a second direction away from the center of the table until second ends of the second legs are received into openings formed in second couplers coupling the second legs to the upper part.

A multipurpose table may include an inner recessed area having a floor, a ledge around at least a portion of the perimeter of the table, and one or more rails between the floor and the ledge. The floor may be adjustable between various heights. A plurality of table covers may rest on the rails and be flush with the ledge. Table accessories may include attachment mechanisms for securing the accessories to the ledge. The attachment mechanisms may include stops insertable through a top surface of the table surface proximate the rail, and a cavity securable around the ledge. A stop receiver may also be positioned around the ledge and capable for receiving the stop.

A proprioceptive foot stimulator assembly having a cross bar that connects to the leg structure of a desk. The assembly includes a bottom channel that pivotably attaches to the cross bar, and a foot stimulating member that attaches to the bottom channel, so that it can pivot in relation to the crossbar. Mounting flanges are located at the longitudinal ends of the cross bar. A pivot assembly, generating the pivotable attachment between the bottom channel and the cross bar, includes two threaded fasteners and a bushing, secured by lock nuts; the bushing connecting the first threaded fastener to the second threaded fastener, such that the second threaded fastener can pivot in relation to the first threaded fastener. In another embodiment, the proprioceptive foot stimulator assembly has at least one slider track capable of being attached to a desk and a foot stimulating member that slidably connects to the slider track.

An embodiment includes a leg height adjustment mechanism that includes a first and second latch arms, a first and second retractors, and an activator. The latch arms each include an engagement structure. The retractors each include a sloped surface and a receiving structure. The receiving structure is engaged with one of the engagement structures of the first or the second latch arms. The first latch arm extends in a first lateral direction and the second latch arm extends a second lateral direction. The second retractor is separated from the first retractor in a second lateral direction that is opposite the first lateral direction. The activator includes angled lower surfaces that are positioned outwardly relative to the sloped surfaces.

A table having a table top having an upper surface and a lower surface. The table further having a first and second guide track located on the lower surface. A first leg is pivotally connected to a second leg, the first leg comprising a first slide adapted to slidably engage the first guide track, and the second leg comprising a second slide adapted to slidably engage the second guide track. The table further includes a first retainer adapted to engage the first slide and the first guide track to prevent sliding of the first slide with respect to the first guide track, and a second retainer adapted to engage the second slide and the second guide track to prevent sliding of the second slide with respect to the second guide track. The table may be an adjustable height table. Other features of the table are also described.

A lifting device including a first platform, a second platform, a gas spring and a locking device is provided. The first platform includes a base and a first column connected to each other. The second platform includes a working table and a second column connected to each other. The second column and the first column are movably connected. The second column has a plurality of engaging holes. The gas spring includes a first end and a second end opposite to each other. The first end connected to the first column, and the second end connected to the second column. The locking device partially disposed at the first column, and a portion of the locking device being adapted to penetrate the engaging holes to fix a relative position between the second column and the first column.

An adjustable leg assembly for use in a bedding product, such as an adjustable bed, may be stabilized by rotating the leg of the leg assembly. To change the length of the leg assembly, a leg must be rotated in the opposite direction to loosen a slotted collar located inside a receiver welded to a frame of the adjustable bed. A wedge is fixed inside the receiver with a push pin assembly above the slotted collar. A threaded member of the leg extends through the wedge. Rotation of the leg moves the leg slightly upwardly relative to the stationary wedge, causing an upper portion of the slotted collar to expand over a portion of the stationary wedge until the slotted collar contacts an inside surface of the receiver and stabilizes the leg assembly.
