       [0001]    This application claims priority to U.S. Provisional Application Ser. No. 61/141,700 filed on Dec. 31, 2008. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention generally relates to seating furniture, and, more particularly, to a modular chair adapted to be utilized on both sloped and/or uneven surfaces. 
       BACKGROUND OF THE INVENTION 
       [0003]    Seating furniture, such as a chair, a tool, a settee, a couch, a sofa, and the like, has been known since time immemorial. The seating furniture ranges from expensive and elaborate fixtures to inexpensive and portable fixtures. Portable seating furniture, such as the chair, finds its utility at multitude of places, indoor as well as outdoors. A wide range of portable, foldable, and compact outdoor chairs is known in the art for providing comfort to a user at outdoor locations. Spectators of outdoor events, such as golf, baseball, and soccer events, firework displays, parades, and the like; and participants in outdoor activities, such as fishing, camping, trekking, and the like, often carry their own outdoor chairs. Such a conventional outdoor chair is beneficial, as the user may place the conventional outdoor chair at any location of his/her choice. 
         [0004]    However, the structural configuration of the conventional outdoor chair is optimized for a leveled or a horizontal surface, and as such, lacks ability to support the user on a sloping or an uneven surface. Sitting on a conventional outdoor chair placed on the sloping or the uneven surface may be uncomfortable for the user, as the user has to constantly make efforts to remain seated on the conventional outdoor chair and to prevent the conventional outdoor chair from toppling. 
         [0005]    Further, the conventional outdoor chair lacks storage capabilities, and as such become burdensome for a user at an outdoor location, as the user also needs to carry other articles, such as a fishing tackle kit, a pack, and the like, along with the conventional outdoor chair. Furthermore, the conventional outdoor chair lacks ability to hold items, such as a can or a bottle of a cold drink, water, and the like, when the user is engrossed in watching an outdoor event, such as a golf or soccer match, a baseball game, firework displays, parades, and the like. 
         [0006]    Accordingly, there exists a need for a modular chair configured to maintain balance and to provide comfortable seating facility to a user in all types of topographical surfaces such as a leveled or a horizontal surface, and a sloping or an uneven surface. Further, there exists a need for a modular chair with storage capabilities. Also, there exists a need for a modular chair, which is capable of holding items, such as a can or a bottle of a cold drink, water, and the like. 
         [0007]    Therefore, it is an object of the present invention to obviate above and other disadvantages from existing art and to provide a modular chair which is configured to maintain balance and to provide comfortable seating facility to a user in all types of topographical surfaces such as a leveled or a horizontal surface, and a sloping or an uneven surface. 
         [0008]    It is further an object of the present invention to provide a modular chair with storage capabilities. 
         [0009]    It is further an object of the present invention to provide a modular chair configured to hold items.
