1. A single arm adjustment mechanism for supporting an object, the single arm adjustment mechanism comprising: a support arm;an upper adjustment assembly coupled to an upper end of said support arm, said upper adjustment assembly capable of being coupled to said object such that said object pivots about a first axis; anda lower adjustment assembly capable of being fixed to a support and pivotally coupled to a lower end of said support arm such that said support arm pivots about a second axis parallel to said first axis in order to maintain said object in a desired angular orientation with respect to said support,wherein said lower adjustment assembly further comprises:a lower adjustment assembly base; anda pivoting member coupled to said support arm such that said support arm pivots about said second axis, said pivoting member having a spindle extending through said lower adjustment assembly base, such that said support arm pivots about said spindle on a third axis,wherein said pivoting member further includes a pair of flanges, said support arm being coupled to said flanges with a pivot pin. 2. The single arm adjustment mechanism of claim 1, wherein said upper adjustment assembly comprises: a housing coupled to said upper end of said support arm;a connecting cylinder having a gear, said connecting cylinder disposed within the housing such that said connecting cylinder is free to rotate within said housing;a base coupled to said connecting cylinder; andan object attaching block slidingly disposed within said base, said object attaching block including a lower portion configured to engage with said gear,wherein said object is coupled to said object attaching block, such that said object may be raised to disengage said lower portion of said object attaching block to allow said object to be rotated about said first axis to a desired position, and said object may be lowered to engage said lower portion of said object attaching block to fix said object in said desired position. 3. The single arm adjustment mechanism of claim 2, wherein said connecting cylinder further comprises: a first roller having a linear slot offset from an axis of said cylinder, said first roller being coupled to one side of said gear;a first slide disposed within said linear slot of said first roller;a second roller having a linear slot offset from an axis of said cylinder, said second roller being coupled to an opposite side of said gear; anda second slide disposed within said linear slot of said second roller,wherein said base is coupled to said first and second slides such that said first and second slides restrict rotational movement of said cylinder to less than 180 degrees. 4. The single arm adjustment mechanism of claim 1, further comprising: a first bushing disposed between each of said flanges and said support arm; anda second bushing disposed between said lower adjustment assembly base and said pivoting member,wherein said first and second bushings provide sufficient friction to hold said support arm in place. 5. The single arm adjustment mechanism of claim 1, wherein said object is a table. 6. The single arm adjustment mechanism of claim 1, wherein said support is an arm of a chair. 7. The single arm adjustment mechanism of claim 1, wherein said support is a backrest of a chair. 8. A single arm adjustment mechanism for supporting an object, the single arm adjustment mechanism comprising: a support arm;an upper adjustment assembly coupled to an upper end of said support arm, said upper adjustment assembly capable of being coupled to said object such that said object pivots about a first axis; anda lower adjustment assembly capable of being fixed to a support and pivotally coupled to a lower end of said support arm such that said support arm pivots about a second axis parallel to said first axis in order to maintain said object in a desired angular orientation with respect to said support,wherein said upper adjustment assembly comprises:a housing coupled to said upper end of said support arm;a connecting cylinder having a gear, said connecting cylinder disposed within the housing such that said connecting cylinder is free to rotate within said housing;a base coupled to said connecting cylinder; andan object attaching block slidingly disposed within said base, said object attaching block including a lower portion configured to engage with said gear,wherein said object is coupled to said object attaching block, such that said object may be raised to disengage said lower portion of said object attaching block to allow said object to be rotated about said first axis to a desired position, and said object may be lowered to engage said lower portion of said object attaching block to fix said object in said desired position. 9. The single arm adjustment mechanism of claim 8, wherein said lower adjustment assembly further comprises: a lower adjustment assembly base; anda pivoting member coupled to said support arm such that said support arm pivots about said second axis, said pivoting member having a spindle extending through said lower adjustment assembly base, such that said support arm pivots about said spindle on a third axis. 10. The single arm adjustment mechanism of claim 9, wherein said pivoting member further includes a pair of flanges, said support arm being coupled to said flanges with a pivot pin.
