FIELD OF THE INVENTION 
       [0001]    The invention relates generally to articles of furniture. More specifically, the invention relates to modular furniture comprising basic elements combinable together to form different types of furniture. 
       BACKGROUND OF THE INVENTION 
       [0002]    Traditional furniture is generally provided as single-piece furniture which is widely used in every aspect of our lives. Different pieces of furniture are usually provided to create a matching set in different environment such as: an office or at home. Generally, an important consideration when buying furniture is to get a piece of furniture that is aesthetically pleasant to a particular decorating taste. However, the functionality and mobility of traditional furniture are limited not only by its aesthetic configuration but also by its size, weight and, in addition to the price which depending on several factors can be expensive. Thus, there would be occasions where one would be discouraged to change or replace a traditional furniture set should the need arises such as when moving to a new house or when redecorating an existing place. Another constraint related to the usage of traditional furniture is the lack of options when it comes to storage and transportation from one placed to another. A large storage area would be needed to accommodate large pieces of furniture and/or an expensive cargo truck would also be needed to transport the furniture from one place to another. 
         [0003]    One inherent problem with traditional single-piece furniture is the inability to convert a piece of furniture into a different piece of furniture. For example, if one has a sofa and desires to have a chair, one would have to get additional pieces of furniture creating a situation where one ends up with at least two complete pieces of furniture and little to none storage space. 
         [0004]    Thus, there is a need for an inexpensive and customizable modular furniture system that provides individuals the opportunity to have a complete set of furniture while allowing to easily convert one piece of furniture to another piece of furniture without the need of acquiring additional pieces of furniture. 
       SUMMARY OF THE INVENTION 
       [0005]    According to one aspect of the invention, a modular furniture system provides a plurality or elements that when selectively combined create a virtually infinite number of possibilities allowing for the customization of every piece of furniture. The size, shape, materials and aesthetic configuration can be selectively chosen to any desired purpose and/or decorating individual taste. 
         [0006]    In another aspect of the invention, when the modular furniture system is unassembled, all the parts are flat, which allows to easily stack all the parts for convenient storage.

       DETAILED DESCRIPTION OF THE INVENTION 
       [0032]    The basic concept of the modular furniture system of the present invention will be explained in detail in conjunction with  FIGS. 1-4 . The system basically comprises of supporting elements  1 , base element  2  and horizontally-extending element  3  which are selectively interchanged and/or interconnected to form a variety of furniture pieces. 
         [0033]      FIG. 1  shows the supporting elements  1  according to the invention. Each supporting element  1  comprises at least one vertically extending slot  1   c  selectively positioned in relation to a top surface portion  1   a . A recessed portion  1   b  is defined on top of said at least one vertically extending slot  1   c  and below the top surface portion  1   a  and is designed to receive the base element  2  as will be explained in detail later. An inclined vertically extending slot  1   c ′ may be diagonally provided when certain inclination is desired on a piece of furniture as will also be explained in detail later. As can be seen on  FIG. 1 , the periphery of each supporting element  1  can be selectively shaped to provide any desired structural and/or aesthetic configuration. It is important to point out that an odd number of slots must be used to preserve the symmetry of the piece of furniture in relation to the base element  2  and horizontally-extending element  3 . 
         [0034]      FIG. 3  shows the base element  2  according to the invention. Each base element  2  has an upper surface  2   b  and a lower surface  2   c . A base slot  2   a  may be provided when certain pieces of furniture are desired. As seen on  FIG. 3 , depending on the particular piece of furniture or application, the base slot  2   a  can be provided on a front portion, a rear portion, a middle portion or any portion of said base element. 
         [0035]      FIGS. 2   a - 2   g  show a plurality of horizontally-extending elements  3  according to the invention. Each horizontally-extending element  3  comprises at least one vertically extending slot  3   a  selectively configured to mate in a sliding relationship with at least one vertically extending slot  1   c  of said supporting element  1 . Depending on the particular piece of furniture or application, the horizontally-extending elements  3  may be provided with additional features or components.  FIG. 2   a  shows an exemplary embodiment having the horizontally-extending element  3  provided with an open portion  3   b . The horizontally-extending element  3  is selectively interconnected with the supporting elements  1  and the base element  2  to form a booth. In another exemplary embodiment, the horizontally-extending element  3  shown in  FIG. 2   c  can be selectively interconnected with supporting elements  1  and base element  2  to form a display/rack arrangement as shown in  FIG. 4 .
