A controller for a furniture drive includes an operating device which includes a speech controller. The speech controller includes a speech control subunit operatively connected to an adjustment drive, and a microphone interacting with the speech control subunit. The speech controller includes three speech control subunits arranged in the operating unit, with two of the speech control subunits forming actuators of adjustment functions and one of the speech control units forming an actuator of stopping the adjustment drive.

A collision detection device is arranged in an adjustable piece of furniture comprising a driving arrangement, and first and second parts being moveable relative to each other. The collision detection device detects a collision during motion of the furniture. The collision detection device comprises a holder as one of the first and second parts of the adjustable piece of furniture to be in contact with a part of the driving arrangement, and a circuit board arranged on the holder, said circuit board comprising a wiring circuit on one of its sides. The holder is configured to, when arranged to the adjustable piece of furniture, transfer a force from the driving arrangement acting on the holder to the circuit board such that said force implies a flexure of the circuit board. An electrical characteristic of the wiring circuit is configured to depend on the flexure of the circuit board.

The present invention relates to a transforming modular trolley and an adjustable axle device for office use, designed to enhance workspace flexibility and ergonomic comfort. The trolley features a modular top assembly with multiple surfaces, including a tilt-able primary work surface, dedicated surfaces for devices and personal items, and integrated storage options. It includes a vertically adjustable axle mechanism for height adjustments, an integrated power management system, and retractable anti-tip stabilizers. The adjustable axle device, available in both gas-spring and electric lift configurations, enables smooth height adjustments and secure locking at user-selected positions, with rotational coupling for customizable orientation. The trolley and axle device are intended for seamless integration into various office environments, offering enhanced usability, stability, and organization. This innovative design addresses the limitations of traditional workstations by providing a compact, mobile solution that supports seated and standing work positions while maintaining a clutter-free workspace.
