Stowable exercise chair for standing desks

Abstract

The chair of the present disclosure balances safety, comfort, ergonomics, numerous desk geometries, a variety of floor surfaces, the physics of cantilevered elements, the height of floor obstacles, and a large range of body types/sizes. It can address the recommendations of ergonomic experts and adds the unique forward footrest/exercise bar for stretching, core workouts, and to increase the variety of ergonomic seating positions. The entire product can fold into a compact light weight package for easy transport and stowage.

         10 . The ergonomic chair of  claim 1 , further comprising a locking shaft pivotally connected to the seat post above the first end. 
     
     
         11 . The ergonomic chair of  claim 10 , wherein the lock is configured to retain a portion of the locking shaft in the first configuration to prevent the locking shaft and the seat post from pivoting in any amount. 
     
     
         12 . The ergonomic chair of  claim 10 ,
 wherein the locking shaft is a piston, including a rod and a barrel, the rod being telescopically received in the barrel,   wherein the barrel is pivotally connected to the seat post, and   wherein the lock is configured to retain a portion of the rod in the first configuration to restrict movement of the seat post to a predetermined range of motion about the first pivot point.   
     
     
         13 . The ergonomic chair of  claim 1 , wherein the seat includes a plurality of handles.
