The off-center relative axis so they extend forwardly, towards user location, considerably greater distance than rearwardly. resilient, foam plastic sleeve placed upon substantially covers each upper, opposite extension portions. ring-like collar, higher surfaces, positioned generally flat may be rested covered laterally restrained between end collars. An adjustable length brace interconnects angularity can adjusted by selectively adjusting for raising lowering order locate pre-selected standing sitting positions.
