         8 . The chair backrest posture apparatus of  claim 7 , wherein the second compressible pad is configured to provide more depth to the chair backrest posture apparatus, and wherein the second compressible pad is narrower in width than the base pad assembly. 
     
     
         9 . The chair backrest posture apparatus of  claim 1 , wherein the base pad assembly comprises an engagement surface that engages the second compressible pad and a second side opposite the engagement surface that engages the back of a chair. 
     
     
         10 . The chair backrest posture apparatus of  claim 9 , wherein the second side of the base pad assembly comprises friction beads that are configured to engage the backrest and keep the base pad assembly in a single location during use. 
     
     
         11 . The chair backrest posture apparatus of  claim 1 , wherein the base pad assembly comprises a plastic sheet sandwiched between two foam base pads. 
     
     
         12 . A chair backrest posture apparatus, the chair backrest posture apparatus comprising:
 a base pad assembly comprising a first compressible pad, wherein the base pad assembly comprises a major length and a minor width, wherein the major length is configured to run vertically on a backrest of a chair and the minor width is configured to run horizontally on the backrest of the chair;   a securing apparatus coupled to the base pad assembly, the securing apparatus configured to secure the chair backrest posture apparatus to the backrest of the chair and position the base pad assembly centrally on the backrest of the chair.   
     
     
         13 . The chair backrest posture apparatus of  claim 12 , further comprising a second compressible pad that is removably coupled to the base pad assembly, wherein the second compressible pad is a different size than the base pad assembly. 
     
     
         14 . The chair backrest posture apparatus of  claim 13 , wherein the second compressible pad is a curved pad with a first flat side that engages with the base pad assembly and a second curved side opposite the first flat side. 
     
     
         15 . The chair backrest posture apparatus of  claim 14 , wherein the curved pad comprises a first flat side that engages with the base pad assembly and a second curved side opposite the first flat side.
