Background

With the development of society, office occupational diseases are on the rise. Conventional desks are either of a constant height or can be custom made in height, but are difficult to change once delivered for use; office staff can work on the desk top at the same height for a long time, and occupational diseases of the waist, the back, the neck or the legs are easy to occur. Many workers are plagued by these occupational illnesses caused by sedentary sitting, and most of all, the popularity of standing office or standing-seat interactive office work has begun abroad. The office has a plurality of advantages, particularly can solve the occurrence of lumbar cervical spondylosis, has the efficacy of losing weight, and can improve the working efficiency by 10-30% through research reports.

Due to the fact that the height of the desktop is not proper due to the fact that two office modes of standing and sitting are required to be switched, a related product for lifting the desktop appears in the market; at present, office staff work with desktop computers, and the office habit of the desktop computers is that a display and a mouse key are placed on different planes, and the height of the display is higher than that of the mouse key, so that the user can be prevented from looking down at the display. The lifting office table adopting the double-layer table platform has the advantages that the table platform cannot be adjusted, so that the storage space and the transportation cost of the lifting office table are increased, and improvement is urgently needed.
