Mechanic support device

A mechanic support device comprising:

• a) a rigid, parallel pair of base legs having horizontal lower portions and upwardly inclined upper portions,
• b) a pair of upper arms telescopically mounted in upper ends of said upper portions of said pair of base legs,
• c) a rigid step slidably mounted to, so as to extend between for substantially vertical sliding over said upper portions of said pair of base legs,
• d) a rigid tray having a resilient pad mounted thereon and slidably mounted on said pair of upper arms, wherein said pair of upper arms include lower sliding sections in said telescopic mounting in said upper ends of said upper portions of said pair of base legs, and upper cantilevered sections extending cantilevered over, substantially vertically aligned with, said lower portions of said pair of base legs,
• wherein said tray is slidably mounted, so as to slide cantilevered outwardly on, said upper cantilevered sections of said pair of upper arms,
• first releasable locking means for releasably locking said step in an elevated position along said upper portions, and second releasable locking means for releasably locking said pair of upper arms in a telescoped position out of said pair of base legs.
