     BACKGROUND OF THE INVENTION 
     Chair designs have an almost unendingly displayed number of possibilities. Chair designs are typically driven by comfort and aesthetic appeal. The present device provides unique features in both comfort and appeal. 
     FIELD OF THE INVENTION 
     The magnetically suspended chair device relates to chairs and more especially to a chair device that provides an electromagnetically suspended seat for comfort and aesthetic appeal. 
     SUMMARY OF THE INVENTION 
     The general purpose of the magnetically suspended chair device, described subsequently in greater detail, is to provide a magnetically suspended chair device which has many novel features that result in an improved magnetically suspended chair device which is not anticipated, rendered obvious, suggested, or even implied by prior art, either alone or in combination thereof. 
     To attain this, the magnetically suspended chair device provides cushioned seating by electromagnetically suspending the seat above the base. This uniquely designed seating further provides aesthetic appeal. The controls may provide only an on/off for the electromagnets. As proximity of the magnets increases repulsive forces, the second electromagnet of the seat bottom will not contact the first electromagnet of the seat base. Additionally, the controls may adjustably control the electromagnets to allow a user to position the height of the seat. 
     Depending upon the seat bottom and seat back design, and the load imposed by a user thereon, the electromagnets may be either centrally or off-center disposed. The arm assemblies may be parallel. The arm assemblies may also be antiparallel, with the guides of the seat assembly in automatically adjusted contact with the arm assemblies. 
     Thus has been broadly outlined the more important features of the improved magnetically suspended chair device so that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated. 
     An object of the magnetically suspended chair device is to provide comfortable seating. 
     Another object of the magnetically suspended chair device is to provide comfortable seating by means of an electromagnetically suspended seat. 
     A further object of the magnetically suspended chair device is to provide unique aesthetic appeal. 
     An added object of the magnetically suspended chair device is to be easily operated by a user. 
     A further object of the magnetically suspended chair device is to provide for seat height adjustment. 
     These together with additional objects, features and advantages of the improved magnetically suspended chair device will be readily apparent to those of ordinary skill in the art upon reading the following detailed description of presently preferred, but nonetheless illustrative, embodiments of the improved magnetically suspended chair device when taken in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF THE DRAWINGS 
     With reference now to the drawings, and in particular  FIGS. 1 through 6  thereof, the principles and concepts of the magnetically suspended chair device generally designated by the reference number  10  will be described. 
     Referring to  FIG. 1 , the device  10  partially comprises a base  20 . A first electromagnet  22  is centrally and upwardly disposed on the base  20 . 
     Referring to  FIG. 5 , the first electromagnetic  22  has a core  23  surrounded by a coil  24 . 
     Referring to  FIG. 6 , the first electromagnet  22  and the second electromagnet  42  each has a first pole  26  spaced apart from a second pole  27 . A magnet case  25  surrounds the first electromagnet  22  and the second electromagnet  42 . 
     Referring to  FIG. 4 , a power supply  28  is connected to the first electromagnet  22 . 
     Referring to  FIG. 2 , a first arm assembly  30  is positioned upwardly on the base  20 . A second arm assembly  31  is spaced apart from the first arm assembly  30  and positioned upwardly on the base  20 . The second arm assembly  31  is parallel with the first arm assembly  30 . A pad  32  is disposed atop each arm assembly. A controls  33  is disposed on at least one of the arm assemblies. A seat assembly  40  is provided. The seat assembly  40  has a seat bottom  41  and a seat back  43 . An at least one guide  44  is disposed on an each side of the seat assembly  40 . More guides  44  may be used. Each guide  44  is configured to slideably interact with one of the each of the arm assemblies, respectively. 
     Referring to  FIG. 3 , the second electromagnet  42  is disposed downwardly on the seat bottom  41 . 
     Referring to  FIG. 4 , the second electromagnet  42  is positioned by the guides  44  to be directly above the first electromagnet  22 . The second electromagnetic  42  has the core  23  surrounded by the coil  24 . The second electromagnet  42  has the first pole  26  spaced apart from the second pole  27 . 
     Referring to  FIG. 6 , the second pole  27  of the second electromagnetic  42  is configured to face the second pole  27  of the first electromagnet  22 . The second electromagnet  42  is in communication with the power supply  28  and the controls  33 . The controls  33  are configured to adjust a repulsive force of the electromagnet poles in positioning the seat assembly  40  above the base  20 . The controls  33  may also be configured to non-adjustably turn on the repulsive force of the two electromagnets. 
     Directional terms such as “front”, “back”, “in”, “out”, “downward”, “upper”, “lower”, and the like may have been used in the description. These terms are applicable to the embodiments shown and described in conjunction with the drawings. These terms are merely used for the purpose of description in connection with the drawings and do not necessarily apply to the position in which the magnetically suspended chair device may be used.
