       wherein the leg support provides support for a user's legs when coupled to a seat and the upper leg supports and lower leg supports are extended. 
     
     
         2 . The portable leg support of  claim 1 , wherein the lower body further comprises a retractable base, the retractable base extending into a position perpendicular to both the longitudinal axis of the lower body and the lower leg supports, the retractable base supporting the portable leg support when extended. 
     
     
         3 . The portable leg support of  claim 1 , further comprising an adjustment mechanism connecting the upper body and the lower body, the adjustment mechanism permitting movement of the lower body relative to the upper body to adjust an overall length of the portable leg support. 
     
     
         4 . The portable leg support of  claim 2 , wherein the retractable base further comprises a height adjustment mechanism, the height adjustment mechanism permitting adjustment of the height of the retractable base when extended. 
     
     
         5 . The portable leg support of  claim 3 , wherein the adjustment mechanism is a telescoping mechanism. 
     
     
         6 . The portable leg support of  claim 4 , wherein the height adjustment mechanism is a telescoping mechanism. 
     
     
         7 . The portable leg support of  claim 1 , wherein the detachable seat coupling comprises a pair of opposing arms, with an arm adjustment mechanism connected to each arm to adjust the distance between the arms. 
     
     
         8 . The portable leg support of  claim 7 , wherein the arm adjustment mechanism is a spring-loaded mechanism. 
     
     
         9 . The portable leg support of  claim 1 , wherein the detachable seat coupling comprises a single arm, the single arm movable between an extended position and a retracted position via a hinge. 
     
     
         10 . The portable leg support of  claim 1 , wherein the upper body and lower body are of similar cross-section, the cross-section being one of: a circle, a square, a rectangle and a semi-circle. 
     
     
         11 . The portable leg support of  claim 1 , wherein the upper leg supports and lower leg supports are of similar cross-section, the cross-section being one of: a square, a rectangle and a semi-circle. 
     
     
         12 . The portable leg support of  claim 1 , wherein the lower body at least partially retractable into the upper body. 
     
     
         13 . A method of securing a portable leg support to a seat, comprising:
 securing the portable leg support to the seat via a detachable seat coupling, the detachable seat coupling having an engagement member to secure the detachable seat coupling to a seat, with the portable leg support comprising:
 an upper body connected to the detachable seat coupling, the upper body having a pair of retractable upper leg supports, the upper legs supports each extending into a position perpendicular to a longitudinal axis of the upper body and being diametrically opposed to each other when extended; and 
 a lower body connected to the upper body, the lower body having a pair of retractable lower leg supports, the lower legs supports each extending into a position perpendicular to a longitudinal axis of the lower body and being diametrically opposed to each other when extended, and 
   extending the upper leg supports and the lower leg supports;   
       wherein the leg support provides support for a user's legs when coupled to the seat and the upper leg supports and lower leg supports are extended. 
     
     
         14 . The method of  claim 13 , wherein lower body of the portable leg support further comprises a retractable base, the retractable base extending into a position perpendicular to both the longitudinal axis of the lower body and the lower leg supports, the retractable base supporting the portable leg support when extended extension arms and the support arms are of similar length. 
     
     
         15 . The method of  claim 13 , further comprising adjusting the portable leg support using an adjustment mechanism connecting the upper body and the lower body, the adjustment mechanism permitting movement of the lower body relative to the upper body to adjust an overall length of the portable leg support. 
     
     
         16 . The method of  claim 14 , further comprising adjusting the portable leg support by adjusting the retractable base using a height adjustment mechanism, the height adjustment mechanism permitting adjustment of the height of the retractable base when extended. 
     
     
         17 . The method of  claim 13 , wherein the lower body is at least partially retractable into the upper body and further comprising a step of extending the lower body from the upper body. 
     
     
         18 . The method of  claim 13 , wherein the upper body and lower body are of similar cross-section, the cross-section being one of: a circle, a square, a rectangle and a semi-circle. 
     
     
         19 . The method of  claim 13 , wherein the upper leg supports and lower leg supports are of similar cross-section, the cross-section being one of: a square, a rectangle and a semi-circle. 
     
     
         20 . The method of  claim 13 , wherein the lower body at least partially retractable into the upper body and further including a step of extending the lower body from the upper body.
