This electric bed is configured to adjust the angle of the back, thigh and leg plates of the mattress-table that installs the mattress. Angle adjustment is achieved by an actuator coupled to the outer frame of the bed, which is configured separately from the mattress, and the mattress is structured to rest on the top of the mattress-table.

In the electric bed according to the related art, a bed frame outside the mattress is essential to fasten and support an angle adjusting device, etc., and it is required to have a frame larger than the size of the mattress. Such an electric bed has a very inconvenient problem when it needs to carry or store the electric bed because of its large volume. In addition, it is difficult to use a bulky electric bed in a small space such as a one-room due to the increasing number of households, and angle adjustment means such as a backrest such as an actuator are exposed on the outside of the mattress, making it easy to install and move the electric bed. Need help from an expert.

On the other hand, the electric bed is often used by the elderly or patients with mobility impairments. Due to the height difference from the ground to the mattress due to the bed frame and bed legs, there is always a risk of falling when the elderly or patients with mobility difficulties get on or off the bed. exist.
