I've built quite a few rockers. Make sure your front legs are the
same length and make sure the back legs are the same length.... the
front doesn't have to be the same length as the back. Make sure the
right side legs and rockers are a mirror image of the left side, i.e.,
front toe-out / back heel-in angles, relative to the center line of
the seat, are the same, or the rocker may creep sideways across the
floor, as you rock.

Three things that make a rocker creep: 1) One leg is too long,
rockers not coplanor, 2) Rocker (front toe-out/back heel-in) angles
not the same, 3) If the chair is correct, the floor (unlevel, carpet
pile, etc.) influences the creep.
