1. Mechanical failure: The mechanical parts inside the bedstead may fail, resulting in the bed not descending smoothly. For example, components such as slide rails, drive systems or motors may be damaged or stuck.

2. Power supply problem: If the automatic invisibility bed needs power supply to run, then it is necessary to check whether the power supply is normal. It may be that the power cord is loose or the circuit of the bed is faulty, which makes it impossible to descend.

3. Operation error: It is possible that you made a mistake in the operation or the operation method is incorrect. Please make sure that you control the operation according to the correct steps and sequence, and that nothing blocks or prevents the bed from descending.
