A control system and a control method of sharing device with liftin function are provided. The portable electronic device sends a request to the cloud server. The cloud server matches the sharing device that meets the request to the portable electronic device so that the portable electronic device have a control right over the paired sharing device. Then the portable electronic device controls lifting or other functions of the sharing device within a specific time, so as to facilitate the management of multiple sharing devices in different places.

The desk with dual desktops includes a first desk member having a first desktop and a number of desk legs beneath the first desktop, and a second desk member joined to a side of the first desk member and having a number of desk legs, a number of support beams on top of the desk legs, and a second desktop above and supported by the support beams. The first desk member and the second desk member can be arranged into an L shape, a T shape, an I shape, or an inverted L shape to suit user's need. By the support beams, the second desktop has an adjustable height that may be selectively configured to be at a different height from that of the first desktop.

A leg/footrest apparatus includes an adjustable-length axle having a compression rod to force first and second ends of the axle away from one another, and a rest platform that is rotatable about an axis of the axle. The apparatus may include a U-shaped member having first and second ends that extend from the axle and a base portion that extends between the first and second ends coupled to the rest platform. The rest platform may be rotatable about the base portion and may be balanced such that a rest surface of the rest platform remains substantially horizontal as the U-shaped member rotates about the axle. The rest platform may be rotatable between an in-use orientation and a storage orientation. A rotational lock may releasably secure the rest platform in the storage orientation. A foot pedal may be configured to rotate the rest platform between the in-use and storage orientations.

A multi-utility table that includes a first platform a substantially a rectangular shape and four vertical members positioned at four corners of the first platform, wherein each vertical member of the four vertical members has a channel and the first platform is slidably mounted to the channels of the four vertical members. Each vertical member has an upper end and a lower end. An actuating member is operably coupled to the first platform for moving the first platform up and down along the channels. A second platform is mounted to the four vertical members near the lower end and below the first platform. A compartment is mounted to the four vertical members near the upper end.
