     SUMMARY OF THE INVENTION 
     A self-contained chair and sofa seating configuration having a plurality of selectively secured cushion seats therewithin and thereon. Single chairs, sofa embodiment functions can afford multiple deploying useful seating configurations in which cushion seats having folded legs can be set up independently of the storage support chair/sofa unit by emulating a chair/sofa arms and back cushions while being removable for use. 
     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to  FIGS. 1-4  of the drawings, a primary basic chair form  10  of the invention can be seen having a chair  11 , with oppositely disposed cushion side arms  12  and  13  and having an upstanding back cushion  13 A. Each of the cushion side arms  12  and  13  function as independent removable cushion seats  14  having a pair of foldable leg assemblies  15 A and  15 B, best seen in  FIGS. 5 and 6  of the drawings. Each cushion seat  14  has a support frame  16  with a cushion  17  extending thereover. The respective leg assemblies  15 A and  15 B having a pair of leg elements  16 A with an interconnecting cross support at  17 . The leg elements  16 A are pivotally secured by respective pivots  18 A and  18 B shown folded position in  FIG. 5  of the drawings and pivoted open support position in  FIG. 6  of the drawings. The cushion seats  14  are supported on the chair by a support frame  19  secured to the chair along each cushion seat to be fitted thereover in frictional registration and held thereon acting as chair arms as seen in  FIG. 1  of the drawings until removed and unfolded for independent use as seen in  FIGS. 3 and 4  of the drawings. A first alternate form of the chair  10 ′ of the invention can be seen in  FIGS. 7 and 8  of the drawings wherein a cushion seat back  21  is added for use as seen in partial deployment in  FIG. 8  of the drawings. 
     Referring now to composite  FIGS. 9A ,  9 B,  10 A, and  10 B the first of five alternate sofas  22  of the invention can be seen wherein a sofa  23  has oppositely disposed side arms  24 , each with a pair of independent cushion seats  14 , as hereinbefore described, positioned there within. A single cushion seat  14 A in each of said side arms  24  can be seen in  FIGS. 10A and 10B  of the drawings. 
       FIGS. 11-14  illustrate a second alternate form of the sofa configuration, as noted, with the sofa frame  25  having opposing arms  26 , each with a removable cushion seat  14 . Each of the arms  26  has a hinged shelf  28  oriented therewithin that can be hinged into use position as seen in  FIGS. 13 and 14  once the cushion seat  14  have been so removed. 
     Referring to  FIGS. 15-18  of the drawings, a third alternate form sofa configuration  26  can be seen wherein a pair of dual arm supports  27 A and  27 B provide sliding engagement for a pair of seat cushions  14  respectively thereon. 
     Sliding hardware assemblies  28  and  28 A can be seen in composite  FIG. 17  of the drawings allowing for trans-lateral sliding deployment and support for the cushion seats  14  there within as will be well understood by those skilled in the art as indicated by directional placement and removal arrows in  FIG. 16  of the drawings. It is evident that this assembly allows for the respective cushion chairs  14  to be slidably removed from the respective sliding support assemblies in pair configuration thus supplementing and increase the number of cushion seats  14  capable within a single chair configuration by diminished dimensional considerations. 
       FIGS. 19-21  show a fourth alternate form of the sofa configuration  30  in which a seat cushion storage and hinge shelf units  31  have been added to both the back  32  and arms  33  of the basic sofa frame as seen and disclosed in  FIGS. 11-14  of the drawings. 
     Referring now to  FIGS. 22 and 23  of the drawings, a fifth alternate form  34  of the sofa configuration can be seen wherein side arms  35  and  36  and a back  37  have insert openings at  35 A,  35 B,  37 A,  37 B, and  37 C respectively into which cushion seats  14  are selectively and removably positioned. Once removed, the defined side arms  35  and  36  and back  37  have finished interior openings  35 A,  35 B,  37 A,  37 B and  37 C in accordance with the style of the furniture. 
     An alternate cushion seat attachment at  40  can be seen in  FIG. 24  of the drawings and composite perspective  FIG. 25 . It can be seen that a sofa back  41  has multiple retaining elements  42 A,  42 B and  42 C, each of which has a beveled top edge portion  43  slanted inwardly. The respective modified cushion seats  14 B have a corresponding inturned engagement edges at  44 A which will be registerably engaged with the sofa back  41  retaining elements  42 A,  42 B and  42 C thus hanging cushion seats  14 B thereon as seen in  FIG. 24  of the drawings or removed for deployment as illustrated in  FIG. 25  of the drawings. 
     It will be evident from the foregoing descriptions that a variety of interengaging removable and deployable furniture seat configurations can be achieved by the hereinbefore described multiple chair sofa seat configurations  14  and  36  of the invention. Its compact self-contained furniture configurations will maximize the space by allowing user arrangement by providing a number of seating use configurations available to the user by the stored and deployable multiple cushion seat configurations acting as harms and backs to either sofas or chairs. 
     It will thus be seen that a new and novel chair/sofa multiple cushion seat integrated component configuration of unique storage utilization furniture has been illustrated and described and it will be apparent to those skilled in the art that various changes and modifications may be made therein without departing therefrom.
