A height adjustable work surface is described that may be utilized as a standalone desk or table, or integrated with a larger work surface to provide selective height adjustability to only a portion of a work surface. The height adjustable work surface preferably utilizes a modular trapezoidal frame structure, including trapezoid tube weldments, corner castings and machined hardened connector pins. The lift mechanism preferably includes parallelogram linkages, pneumatic gas cylinders, sliding brake bar mechanism and brake release handles to provide height adjustment functionality.

An adjustable platform having an upper platform surface, at least two leg assemblies supporting the upper platform surface, and a drive mechanism that is configured to extend or retract the leg assemblies between a first position, in which each leg assembly is retracted to lower the platform toward ground, and a second position, in which each leg assembly is extended to raise the platform away from the ground. The drive mechanism includes a single motor that is drivingly coupled to each of the at least two leg assemblies, in which the drive mechanism is configured to simultaneously extend or retract both of the at least two leg assemblies between the first position and second position to thereby lower or raise the upper platform surface relative to the ground.

Methods and systems for reminding a user to adjust a height adjustable workstation that includes a worktop supported by a frame, an interface including user input controls and a vertical displacement drive mechanism, the user input controls including at least one input control, each of the user input controls for receiving manual direct user selections from a workstation user to activate the drive mechanism to initiate worktop elevation adjustments to a different worktop elevation positions, an exemplary method comprising the steps of monitoring at least one condition related to ongoing use of the worktop over a period of time while a user is associated with the worktop and when the at least one condition occurs, without any user selection to initiate a change in worktop height via the interface subsequent to the at least one condition occurring, moving the worktop to remind the user to perform some activity.

An automatic elevation-adjusting system includes an elevating unit, a control panel, a setting module, a calculating module and a central control module. The control panel includes a power icon, a direction icon unit, a setting icon, and a mode icon unit. The setting icon is operable to actuate the setting module to allow a user to press the direction icon unit and the power icon to enter data including a name, height, sex and age. The calculating module calculates average elevations for playing games, writing, reading and standing based on the user's sex and age, a pre-set specification of the table and an average height corresponding to the user's sex and age. The central control module actuates the elevating unit to move a table to the average elevation for playing games, writing, reading or standing when the game, writing, reading or standing icon of the mode icon unit is pressed.

A system for adjusting a height of a workstation, comprising a height adjust system for a workstation, the height adjust system being adjustable in elevation, a worktop mounted to the height adjustment system for movement therewith to different positions, a first sensor device for sensing the presence of a workstation user within a space associated with the workstation, a processor that tracks and stores at least the duration of time that the worktop is in at least one of a sitting position and a standing position while a user is within the space associated with the workstation, the processor further providing a user with a reminder to change a current position of the worktop to another position.

A workstation includes a partition unit to form a workspace, in which a desk board, two lifting apparatuses and a driving device are provided. Each of the lifting apparatuses has a first tubular member connected to a bottom of the desk board, a second tubular member fixed to the partition unit, and a lifting device to move the first tubular member relative to the second tubular member. The driving device is connected to the lifting devices to drive the lifting devices to move the first tubular members so as to lift and lower the desk board.

A desk includes a tabletop and at least one base member supporting the tabletop. A footrest is disposed on the at least one base member beneath the tabletop. The footrest is movable between a stowed position toward a back of the desk and a deployed position toward a front of the desk. At least one mechanism is disposed on the at least one base member and operatively coupled to the footrest. The at least one mechanism moving the footrest between the stowed and deployed positions. A floor mat is disposed with the footrest. The floor mat is movable with the footrest between a stowed mat position and a deployed mat position.
