The length of standard dimension metal tubing  2  projects upwards at 90 degrees angle to the parallel front portion of the square front facing section  1 . Located on the vertical section of standard dimension metal tubing  2 , orientated parallel to the parallel front portion of the square front facing section  1  are the interlocking ankle and foot protrusions  3  comprised of two equal lengths of standard dimension round metal tubing advantageously adjoined to the vertical section of standard dimension metal tubing  2 .  
         [0016]     Advantageously form fitting to the outer circumference of the two equal lengths of standard dimension round metal tubing is polyurethane foam padding comprising protrusions  3 .  
         [0017]     The standard dimension metal tubing  2  continues projecting upwards to a point whereto it is advantageously formed to turn towards the rear of the front facing section  1  at a 90 degree angle to the vertical section of standard dimension metal tubing  2 , orientated parallel to the transverse portions of the square front facing section  1 . Advantageously adjoined thereon the top of the section of standard dimension metal tubing  2  which is orientated parallel to the transverse portions of the square front facing section  1 , are the interlocking knee protrusions  4  comprised of a length of standard dimension round metal tubing advantageously adjoined to the standard dimension metal tubing  2  projecting vertically upwards at 90 degrees from the standard dimension metal tubing  2 . Advantageously adjoined to the standard dimension round metal tubing projecting upwards is a corresponding length of standard dimension round metal tubing orientated identically to protrusions  3 . Advantageously form fitting to the outer circumference of the length of standard dimension round metal tubing is polyurethane foam padding comprising protrusions  4 .  
         [0018]     The standard dimension metal tubing  2  continues towards the rear of the square front facing section  1 . The standard dimension metal tubing  2  is then advantageously formed to project downwards at a 45 degree angle towards the metal cross member  11 .  
         [0019]     Whereon it is advantageously adjoined to a section of standard dimension round metal tubing  5  which is advantageously adjoined to the top and middle area of metal cross member  11 . The adjoining section of standard dimension round metal tubing  5  projects upwards at a 90 degree angle to metal cross member  11 . The section of standard dimension round metal tubing  5  continues upwards to a point where the end is advantageously terminated thereby leaving the end open to facilitate within the inside diameter of section  5  the fitting and free rotational movement of a corresponding smaller standard dimension section  17  of round metal tubing.  
         [0020]     Referring now more particularly to  FIGS. 2, 7  and  6 .

The flat contact area of each of the corresponding threaded nuts  12  are thereto advantageously adjoined to the corresponding flat contact area of the standard dimension square metal tubing  14 .  
         [0022]     Advantageously located thereon the S.A.E. standard dimension threaded rod  13  on the correspondingly opposite side of the flat contact area of the S.A.E. standard dimension threaded nuts  12  and the standard dimension square metal tubing  14  is a identical length and S.A.E. standard dimension threaded rod  21 . This is advantageously adjoined at a 90 degree angle forming a+shape to the S.AE. standard dimension threaded rod  13 . Thereto on each end of the S.A.E. standard dimension threaded rod  21  are correspondingly sized S.A.E. standard dimension threaded nuts  8 . The flat contact area of the corresponding S.A.E. standard dimension threaded nuts  8  are advantageously adjoined to the corresponding flat contact area of a length of standard dimension square metal tubing  22  identical to the length of standard dimension square metal tubing  14 . This comprises the multi-directional joint embodiment.  
         [0023]     Referring now more particularly to  FIGS. 3-7   
         [0024]     Advantageously adjoined to the opposite and corresponding flat area of the standard dimension square metal tubing  22  that is adjoined to the S.A.E. standard dimension. threaded nuts  8  is a length of standard thickness and width flat metal  16  orientated parallel to the standard dimension square metal tubing  22 . Advantageously adjoined to the middle area of the standard thickness and width flat metal  16  at 90 degrees angle are two equal length sections of standard thickness and width flat metal  15  which are the same corresponding thickness and width as the standard thickness and width flat metal  16 .  
         [0025]     Advantageously attached to the corresponding flat sides of the standard thickness and width flat metal sections  16  and  15  is the corresponding flat side of a section of standard wood sheeting  18 . Advantageously attached to the standard thickness and width flat metal  15  and the standard wood sheeting  18  is a standard nylon belt  19  with a locking and unlocking buckle attachment  20 . Advantageously attached to the corresponding flat side of the standard wood sheeting  18  opposite the flat corresponding side of the standard wood sheeting thereto attached to the standard thickness and width flat metal sections  16  and  15  is a corresponding section of polyurethane foam padding of the same length and width as the corresponding section of standard wood sheeting  18 . Thereto covering the section of polyurethane foam is a section of polyvinyl sheeting which is therein advantageously attached to the standard wood sheeting  18  to completely and advantageously cover the section of polyurethane foam therein comprising section  9 . This forms an embodiment of a flat seating surface capable of multi-directional movement.
