         2 . The adjustable support apparatus of  claim 1 , wherein the first upright support member includes a first opening in which a first end of a first post is slidably supported, a second end of the first post is pivotally connected to the first support, and a first height of the first post is adjustable via a first adjustment mechanism with respect to the first upright support member. 
     
     
         3 . The adjustable support apparatus of  claim 2 , wherein the first upright support member is pivotally connected to at least one of the horizontal support members. 
     
     
         4 . The adjustable support apparatus of  claim 2 , wherein the first adjustment mechanism includes a first spring-loaded pin, the first upright support member includes a first plurality of holes for the first spring-loaded pin, and the first post includes a first plurality of guide holes. 
     
     
         5 . The adjustable support apparatus of  claim 1 , wherein the second upright support member includes a second opening in which a first end of a second post is slidably supported, a second end of the second post is pivotally connected to the second support, and a second height of the second post is adjustable via a second adjustment mechanism with respect to the second upright support member. 
     
     
         6 . The adjustable support apparatus of  claim 1 , wherein the first upright support member includes a first mounting portion and the third horizontal support member includes a base mounting portion, and
 a third adjustment mechanism including at least one adjustment shaft having a first end connected to the first mounting portion, and a second end connected to the base mounting portion, such that a length of the at least one adjustment shaft is adjustable between the first mounting portion and the base mounting portion.   
     
     
         7 . The adjustable support apparatus of  claim 6 , wherein the third adjustment mechanism includes two adjustment shafts. 
     
     
         8 . The adjustable support apparatus of  claim 1 , wherein the first support and the second support are arranged facing each other. 
     
     
         9 . The adjustable support apparatus of  claim 1 , wherein the first support is configured to support a posterior side of a user. 
     
     
         10 . The adjustable support apparatus of  claim 1 , wherein the second support is configured to support a lower extremity of a user. 
     
     
         11 . The adjustable support apparatus of  claim 1 , further comprising a third upright support member positioned adjacent to the second upright support member, wherein the third upright support member includes a third opening in which a first end of a third post is slidably supported, and a second end of the third post includes a pivoting connection to a support surface. 
     
     
         12 . The adjustable support apparatus of  claim 1 , wherein at least one of the horizontal support members includes wheels.
