Description

Technical Field

[0001] The utility model relates to the technical field of furniture, in particular to a liftable electric bed. Background Art

[0002] The commonly used bed surface is flat. People hope to read books or do other activities in bed. However, the flat bed can only be supported by pillows or other items behind the back, which is extremely inconvenient. To solve the above problem, a lifting bed is designed, in which the head of the bed rises upward to form a slope.

[0003] However, most of the existing electric beds only have the headboard that can be raised and lowered, and the functions are relatively simple, which has certain limitations when used. Therefore, we propose a liftable electric bed to solve the above problems. Utility Model Content
