A height-adjustable desk with a force-load adjustment device that allows the table top to be raised and lowered with a force largely independent of the load on the table. The adjustment device includes a mechanical energy storage device like a gas spring, hydraulic cylinder, or pneumatic piston. This energy storage device can be connected to a load sensor like a short-stroke hydraulic cylinder or piezo sensor. The load sensor detects the force on the table and transmits a signal to the adjustment device. The adjustment device moves the energy storage device piston to compensate for the load changes and maintain consistent lifting force. This enables easy height adjustment regardless of table weight.

A desktop lifting platform with enhanced safety features, incorporating sensors to detect obstacles and tilting. The platform uses sensors such as tilt switches, mechanical switches, or strain gauges to identify if it hits an object or tilts. When an anomaly is detected, the controller is signaled to stop lifting, preventing damage to the platform and items on it. Lifting can resume once the obstacle is removed or the tilt is corrected. These sensors can be located on the column, desktop, or base.
