What kind of feature is the 'Anti-Collision Stop' mentioned in the description?

Translating the name literally, it roughly means collision-prevention stop. With an electric height-adjustable desk, it is difficult for a person to keep track of everything placed above or below the tabletop while it is moving up and down. The Anti-Collision Stop on the LEFF motion desk is a feature designed to automatically Roll-Back, in other words, reverse direction, if it collides with something during operation^[1]. This means that instead of merely stopping at the point of impact, it backs away in the opposite direction from which it was moving, creating space to pull out trapped objects or hands.

There are two ways to adjust the height. You can finely raise and lower it in 1mm increments using the control switch, and you can save up to 3 frequently used height levels^[2]. The memory function is typically used by saving separate heights for sitting work and standing work, alternating between them with a single button press.

hmmm, it is easier to understand these two features by looking at them as a pair rather than separately. The more a desk can automatically raise its tabletop to a target height with a single button press, the more likely a person is to take their hands off and look elsewhere, and that is precisely when there is room for it to make contact with a drawer unit under the desk or an armrest of a chair.
