Stand at ease (United States: parade rest) has the soldiers in a more relaxed position. The left foot is moved roughly 10 inches to the left from the position of attention so they are shoulder length apart. Simultaneously, they clasp their hands behind their backs with the left hand resting flat on the small of the back and the right hand resting flat on top of the left. Their fingers are extended and joined, thumbs interlocked and palms are facing out behind them. No movement is permitted.

This is often, but not always, followed by an implicit "relax" ("rest"). This is typically used when being addressed or lectured for a long period of time where the positions of attention or at ease would be too painful or uncomfortable to hold.
Relax (United States: rest): The only parade instruction given in an ordinary voice, rather than the raised, emphatic parade voice. This is the only position that actually offers soldiers freedom of movement. Soldiers are typically allowed to move other than moving their feet, though, when it is given by a high-ranking officer, soldiers typically move a minimal amount after a bit of stretching.
