Description:
BACKGROUND OF THE INVENTION  
         [0001]    1) Field of the Invention  
           [0002]    The invention herein relates to computer furniture, specifically an improved structure multifunction computer chair support apparatus.  
           [0003]    2) Description of the Prior Art  
           [0004]    As modern society becomes computerized, employment that requires being seated for extended periods has resulted in numerous fatigue-induced physical injuries. Modem business offices are equipped with chairs and desks, and office workers sit on chairs to operate desktop computers, wherein a mouse is manually utilized, the repetitive maneuvering of which leads to another type of work-related injury. As users operate computers, they lean directly against the hard desk when tired. If done for a prolonged length of time, hands ache from fatigue, with the continuous posturing of the head in the same position also resulting in similar discomfort from weariness. Due to equipment limitations, businesses only have office-use desk and chairs, with few having physical fitness equipment. As such, when personnel become tired after a period of work, they can only stand up and move about; there is no equipment for exercising and thereby shortening rest periods.  
         SUMMARY OF THE INVENTION  
         [0005]    The objective of the invention herein is to provide the said computer chair support apparatus which consists of foldable chair legs, an elbow cushion situated at the upper extent, a knee cushion disposed medially on one side, and an adjustment structure disposed at the lower extent of the elbow cushion and the knee cushion, wherein utilizing the said adjustment structure enables the free adjustment of the elbow cushion and the angle of the knee cushion; during computer operation, the elbows are straddled on the elbow cushion and the legs are postured against the knee cushion to increase the comfort of the user and, furthermore, the user can also lean on the elbow cushion to rest and, furthermore, utilize the computer chair for physical fitness exercising.
