A variable height platform system comprises a tabletop, a frame assembly for supporting the tabletop, a drive mechanism, a sensor, and a controller. The drive mechanism is configured to set a height of the frame assembly and the tabletop in an elevated position for use. The sensor is configured to sense position and movement of a user in a predetermined area including an area of the variable height platform system and an area proximate the variable height platform system. The controller is operatively connected to the sensor and drive mechanism. The controller is configured to operate the drive mechanism in response to the sensor sensing the position and movement of the user in the predetermined area.

Improvements to a desk and exercise semi-recumbent bicycle is disclosed, the desk allows a person exercising while utilizing the desk with a computer, as a table or read a book. The desk has a 6-way adjustment relative to the seat for elevation of the desk, angle, sliding forward and backward of the desk or the proximity of the desk relative to the chair and or the pedals. The desk pivots to allow the desk to be easily tilted towards the user when they are studying and tilted away from the user when the user wants to exit the exercise bicycle. The dimension from the seat to the pedals is adjustable to accommodate these different desires. The amount of resistance can be adjusted to increase or decrease the difficulty to accommodate different levels of activity. A recording mechanism can count distance, elapsed time, calories or other information.

An adjustable height platform is disclosed. The example adjustable height platform provides a first stage of uprights coupled to a lower platform and a second stage of uprights coupled to a lower platform. The first and second stage are coupled by a bracket with three pivot points. A first lower upright and a first upper upright couple to distinct pivot points on the bracket and a second lower upright and second upper upright couple to a common pivot point on the bracket. A first-to-second stage transfer mechanism transfer rotation force from the first stage of uprights to the second stage of uprights. The upper platform includes a height fixing mechanism release to interface with a height fixing mechanism coupled to the first upper upright to fix the height of the adjustable height platform.

A table or desk includes: a surface; a substrate, wherein the surface is attached to an upper plane of the substrate; and at least one leg directly or operatively connected to an underneath side of the substrate, wherein the leg is height adjustable. The height of the table or desk can be adjusted by raising and lowering the surface and the substrate via a motor. The motor can be controlled by a variety of mechanisms and can adjust the height by moving telescoping leg segments into and out of position with each other. The table or desk can be used in a home or office setting.

An adjustable power and data rail for static height and vertically adjustable desks. The adjustable power and data rail fits between the static height and vertically adjustable desks and expands as needed either horizontally or vertically to match the installation configuration with paired multiple desks. The power and data rail provides connectivity for each of the static height or vertically adjustable desks to data and power connectors.
