The Smart Bed features an automatic system that is activated three seconds after the last person gets out of the bed.
Mechanical arms extend on each of the sides to grab the edges of the duvet, while a set of rollers slowly smooth down the bed. At the same time levers then lift and straighten the pillows.
The entire process takes less than a minute. According to the company, it is impossible for the bed to start functioning on accident while a person is sleeping.
